ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/jic23/iio into char-misc-next Pull IIO updaate from Jonathan: IIO: 1st set of new device support, features and cleanup for 6.14 Fairly quiet cycle. Usual mix of new drivers, device support in existing drivers, features and more general rework and cleanup. There are a few late breaking or long standing but complex fixes in here as well. There is one expected merge conflict due to an upstream fix touching neighboring code in ti-ads1119. The trivial resolution is the right one with the result ending up as: struct { s16 sample; aligned_s64 timestamp; } scan; New device support ================== adi,ad4000 - Add support for many Pulsar ADC devices: AD7685, AD7686, AD7687, AD7688, AD7690, AD7691, AD7693, AD7942, AD7946, AD7980, AD7982, AD7983, AD7984, AD7988-1 and AD7988-5 ADCs. Generally similar to the AD4000 series but with lower sampling rates and no configuration registers. Includes addition of timestamp channels. adi,adis16480 - Add support for ADIS16486, ADIS16487 and ADIS16489 IMUs. Required a few tweaks to existing driver and addition of tables. kionix,kx022a - Add support for KX134ACR-LBZ accelerometer that is similar to the KX132ACR-LBZ but with a wider (+-64G) sensor range. - Add support for KX134-1211 accelerometer that is similar to the KX132-1211 but with a wider (+-16G) sensor range. nxp,fxls8962af - Add support for fxls8974cf and fxls8967af accelerometers, Both are compatible with fxls8962af but with different device IDs which are used in presence checks. renesas,rzg2l - Add support for Renesas RZ/GS3 SoC ADCs (various driver refactors precede this to allow for chip differences). rohm,bd79704 - New driver for this 6 channel DAC. st,mpu6050 - Support he IAM20380 which is effectively a cut down IAM20608 IMU with only a gyroscope (no accelerometer). st,stm-timmer-trigger - Add support for ADC trigger use case for the STM32MP25 SOC. Do not support the counter functionality in this driver as that is handled by the counter subsystem. ti,opt4060 - New driver for this RGBW color sensor. Driver drop =========== rohm,bu20008 - Drop as decision was made to not mass produce this light sensor after Matti had done all the work to get a driver upstream. Features ======== adi,ad_sigma_delta library + ad7124 - Allow for GPIO to check interrupt status, enabling this device on more platforms that don't obey prior (non general) assumptions on how the interrupt chips work. - Allow variation in reset sequence length allowing chip specific optimizations rather than always using worst case. adi,ad7124 - Add temperature channel support. adi,ad7173 - Add support calibration modes for this family of ADCs. adi,adxl345 - Binding update to allow specification of which interrupt line is connected (or none). - Support interrupts and FIFO based data capture. bosch,bme680 - Add regulators support. Note this required a new binding doc rather than use of trivial-devices - Runtime PM support. microchip,pac1921 - Add ACPI support including _DSM for shunt value and label. renesas,rzg2l - Enable runtime autosuspend. - Add suspend and resume support. tyhx,hx9023s - Add loading of a firmware file used to set defaults for some configuration registers. vishay,veml6030 - Support triggered buffers allowing efficient data capture at higher speeds. - Add regmap cache to reduce access to device. Cleanup and minor fixes ======================= cross-tree - Another batch of conversions to devm_regulator_get_enable_read_voltage() helper and related conversions to full devm that this enables. - Various patches using guard() to allow early returns and simpler code flow. - Various conversions from s64 timestamp __aligned(8) to aligned_s64 type. Includes a few cleanups where this unsigned and it should have been signed. - Fix up some missing types for drive-open-drain in dt-binding docs. core - Add missing documentation for iio_dmaengine_buffer_setup_ext() - Add check that all buffers passed to iio_read_channel_ext_info() and iio_read_channel_label() are page sized and page aligned. Done this way because the callbacks are almost always only used to fill sysfs attributes. The check covers the tiny percentage of cases where use is made of this data in a consumer driver. - Mark scan_timestamp memory of struct iio_dev private ensuring no drivers change the value which belongs to the IIO core. documentation - Various missing ABI docs added. - ABI docs made to use Y consistently as the wildcard for channel number. - Combine duplicate in_currentY_raw entries in ABI docs. iio-mux - Fix alignment of buffers passed to iio_channel_read_ext_info(). adi,ad_sigma_delta library - Respect keep_cs_asserted flag in read path. - Close a race condition around irq enabling and disabling. - Use explicit unsigned int in place of unsigned. adi,ad6695 - Move dt-binding header under adc sub-directory and fix include path in dt example. adi,ad7124 - Check number of channels in DT doesn't exceed what the driver can handle. - Check input specified in DT are possible. - Improved error reporting during probe. adi,ad7173 - Drop unused structure element. adi,ad7293 - Ensure power is turned on before resetting. adi,adxl345 - Some documentation simplification and parameter renames. - Add a function than unifies handling of power up and power down. - Add defines to have a complete set of registers defined. - Add missing \n to end of error messages. amlogic,meson_saradc - Simplify handling of the REG11 register access. awinic,aw96104 - Constify iio_info structure. bosch,bmp085 - Add to dt-binding to indicate devices support SPI. bosch,bmp280 - Use sizeof() to replace a somewhat magic 2. - Rename sleep related variables so the unit is included and use fsleep() to replace usleep_range() calls. bosch,bno055 - Constify struct bin_attribute capella,cm3232 - Reset device before checking hardware ID inline with suggested flow from datasheet. diolan,dln2 - Simplify zeroing of structure used to gather up data by just clearing the whole thing before writing rather than trying to clear out he padding after write. freescale,vf610 - Use devm_ and dev_error_probe() to simplify code and allow dropping of explicit remove() callback. invensense,timestamp library - Use a cast to remove possibility of integer overflow. kionix,kx022a - Increase reset delay a little. maxim,max1363 - Use a buffer of sufficient size in iio_priv() rather than allocating variable sized buffer at use time. microchip,mcp4725 - Replace of_property_read_bool() with of_property_present() for detecting presence of regulator which is obviously not a bool. nxp,fxls8962af - Add wakeup-source property to the dt binding to allow these sensors to wake the system up from suspend. - Enable finer grained build when not all bus types need to be supported. renesas,rzg2l - Use dev_err_probe(), improving handling of probe errors and simplifying code. - Convert to devm_ based cleanup. - Remove unnecessary runtime PM complexity as clocks are managed through PM domains. - Switch pm_ptr() removing need for __maybe_unused markings. - use read_poll_timeout() to replace open coded equivalent. samsung, ssp_sensors - Simplify code by always providing timestamp whether or not it is enabled. st,lsm6dsx - Avoid need to include linux/i3c/master by using i3cdev_to_dev() to get to the contained struct device. st,stm32-timer-trigger - Check for clk_enable() fails. vishay,veml6030 - Use new gts-helper functions and fix the _scale attribute to take into account changes in gain and integration time.

Add a new "charge_types" property, this is identical to "charge_type" but reading returns a list of supported charge-types with the currently active type surrounded by square brackets, e.g.: Fast [Standard] "Long_Life" This has the advantage over the existing "charge_type" property that this allows userspace to find out which charge-types are supported for writable charge_type properties. Drivers which already support "charge_type" can easily add support for this by setting power_supply_desc.charge_types to a bitmask representing valid charge_type values. The existing "charge_type" get_property() and set_property() code paths can be re-used for "charge_types".

git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci Pull PCI updates from Bjorn Helgaas: "Enumeration: - Make pci_stop_dev() and pci_destroy_dev() safe so concurrent callers can't stop a device multiple times, even as we migrate from the global pci_rescan_remove_lock to finer-grained locking (Keith Busch) - Improve pci_walk_bus() implementation by making it recursive and moving locking up to avoid need for a 'locked' parameter (Keith Busch) - Unexport pci_walk_bus_locked(), which is only used internally by the PCI core (Keith Busch) - Detect some Thunderbolt chips that are built-in and hence 'trustworthy' by a heuristic since the 'ExternalFacingPort' and 'usb4-host-interface' ACPI properties are not quite enough (Esther Shimanovich) Resource management: - Use PCI bus addresses (not CPU addresses) in 'ranges' properties when building dynamic DT nodes so systems where PCI and CPU addresses differ work correctly (Andrea della Porta) - Tidy resource sizing and assignment with helpers to reduce redundancy (Ilpo Järvinen) - Improve pdev_sort_resources() 'bogus alignment' warning to be more specific (Ilpo Järvinen) Driver binding: - Convert driver .remove_new() callbacks to .remove() again to finish the conversion from returning 'int' to being 'void' (Sergio Paracuellos) - Export pcim_request_all_regions(), a managed interface to request all BARs (Philipp Stanner) - Replace pcim_iomap_regions_request_all() with pcim_request_all_regions(), and pcim_iomap_table()[n] with pcim_iomap(n), in the following drivers: ahci, crypto qat, crypto octeontx2, intel_th, iwlwifi, ntb idt, serial rp2, ALSA korg1212 (Philipp Stanner) - Remove the now unused pcim_iomap_regions_request_all() (Philipp Stanner) - Export pcim_iounmap_region(), a managed interface to unmap and release a PCI BAR (Philipp Stanner) - Replace pcim_iomap_regions(mask) with pcim_iomap_region(n), and pcim_iounmap_regions(mask) with pcim_iounmap_region(n), in the following drivers: fpga dfl-pci, block mtip32xx, gpio-merrifield, cavium (Philipp Stanner) Error handling: - Add sysfs 'reset_subordinate' to reset the entire hierarchy below a bridge; previously Secondary Bus Reset could only be used when there was a single device below a bridge (Keith Busch) - Warn if we reset a running device where the driver didn't register pci_error_handlers notification callbacks (Keith Busch) ASPM: - Disable ASPM L1 before touching L1 PM Substates to follow the spec closer and avoid a CPU load timeout on some platforms (Ajay Agarwal) - Set devices below Intel VMD to D0 before enabling ASPM L1 Substates as required per spec for all L1 Substates changes (Jian-Hong Pan) Power management: - Enable starfive controller runtime PM before probing host bridge (Mayank Rana) - Enable runtime power management for host bridges (Krishna chaitanya chundru) Power control: - Use of_platform_device_create() instead of of_platform_populate() to create pwrctl platform devices so we can control it based on the child nodes (Manivannan Sadhasivam) - Create pwrctrl platform devices only if there's a relevant power supply property (Manivannan Sadhasivam) - Add device link from the pwrctl supplier to the PCI dev to ensure pwrctl drivers are probed before the PCI dev driver; this avoids a race where pwrctl could change device power state while the PCI driver was active (Manivannan Sadhasivam) - Find pwrctl device for removal with of_find_device_by_node() instead of searching all children of the parent (Manivannan Sadhasivam) - Rename 'pwrctl' to 'pwrctrl' to match new bandwidth controller ('bwctrl') and hotplug files (Bjorn Helgaas) Bandwidth control: - Add read/modify/write locking for Link Control 2, which is used to manage Link speed (Ilpo Järvinen) - Extract Link Bandwidth Management Status check into pcie_lbms_seen(), where it can be shared between the bandwidth controller and quirks that use it to help retrain failed links (Ilpo Järvinen) - Re-add Link Bandwidth notification support with updates to address the reasons it was previously reverted (Alexandru Gagniuc, Ilpo Järvinen) - Add pcie_set_target_speed() and related functionality so drivers can manage PCIe Link speed based on thermal or other constraints (Ilpo Järvinen) - Add a thermal cooling driver to throttle PCIe Links via the existing thermal management framework (Ilpo Järvinen) - Add a userspace selftest for the PCIe bandwidth controller (Ilpo Järvinen) PCI device hotplug: - Add hotplug controller driver for Marvell OCTEON multi-function device where function 0 has a management console interface to enable/disable and provision various personalities for the other functions (Shijith Thotton) - Retain a reference to the pci_bus for the lifetime of a pci_slot to avoid a use-after-free when the thunderbolt driver resets USB4 host routers on boot, causing hotplug remove/add of downstream docks or other devices (Lukas Wunner) - Remove unused cpcihp struct cpci_hp_controller_ops.hardware_test (Guilherme Giacomo Simoes) - Remove unused cpqphp struct ctrl_dbg.ctrl (Christophe JAILLET) - Use pci_bus_read_dev_vendor_id() instead of hand-coded presence detection in cpqphp (Ilpo Järvinen) - Simplify cpqphp enumeration, which is already simple-minded and doesn't handle devices below hot-added bridges (Ilpo Järvinen) Virtualization: - Add ACS quirk for Wangxun FF5xxx NICs, which don't advertise an ACS capability but do isolate functions as though PCI_ACS_RR and PCI_ACS_CR were set, so the functions can be in independent IOMMU groups (Mengyuan Lou) TLP Processing Hints (TPH): - Add and document TLP Processing Hints (TPH) support so drivers can enable and disable TPH and the kernel can save/restore TPH configuration (Wei Huang) - Add TPH Steering Tag support so drivers can retrieve Steering Tag values associated with specific CPUs via an ACPI _DSM to improve performance by directing DMA writes closer to their consumers (Wei Huang) Data Object Exchange (DOE): - Wait up to 1 second for DOE Busy bit to clear before writing a request to the mailbox to avoid failures if the mailbox is still busy from a previous transfer (Gregory Price) Endpoint framework: - Skip attempts to allocate from endpoint controller memory window if the requested size is larger than the window (Damien Le Moal) - Add and document pci_epc_mem_map() and pci_epc_mem_unmap() to handle controller-specific size and alignment constraints, and add test cases to the endpoint test driver (Damien Le Moal) - Implement dwc pci_epc_ops.align_addr() so pci_epc_mem_map() can observe DWC-specific alignment requirements (Damien Le Moal) - Synchronously cancel command handler work in endpoint test before cleaning up DMA and BARs (Damien Le Moal) - Respect endpoint page size in dw_pcie_ep_align_addr() (Niklas Cassel) - Use dw_pcie_ep_align_addr() in dw_pcie_ep_raise_msi_irq() and dw_pcie_ep_raise_msix_irq() instead of open coding the equivalent (Niklas Cassel) - Avoid NULL dereference if Modem Host Interface Endpoint lacks 'mmio' DT property (Zhongqiu Han) - Release PCI domain ID of Endpoint controller parent (not controller itself) and before unregistering the controller, to avoid use-after-free (Zijun Hu) - Clear secondary (not primary) EPC in pci_epc_remove_epf() when removing the secondary controller associated with an NTB (Zijun Hu) Cadence PCIe controller driver: - Lower severity of 'phy-names' message (Bartosz Wawrzyniak) Freescale i.MX6 PCIe controller driver: - Fix suspend/resume support on i.MX6QDL, which has a hardware erratum that prevents use of L2 (Stefan Eichenberger) Intel VMD host bridge driver: - Add 0xb60b and 0xb06f Device IDs for client SKUs (Nirmal Patel) MediaTek PCIe Gen3 controller driver: - Update mediatek-gen3 DT binding to require the exact number of clocks for each SoC (Fei Shao) - Add support for DT 'max-link-speed' and 'num-lanes' properties to restrict the link speed and width (AngeloGioacchino Del Regno) Microchip PolarFlare PCIe controller driver: - Add DT and driver support for using either of the two PolarFire Root Ports (Conor Dooley) NVIDIA Tegra194 PCIe controller driver: - Move endpoint controller cleanups that depend on refclk from the host to the notifier that tells us the host has deasserted PERST#, when refclk should be valid (Manivannan Sadhasivam) Qualcomm PCIe controller driver: - Add qcom SAR2130P DT binding with an additional clock (Dmitry Baryshkov) - Enable MSI interrupts if 'global' IRQ is supported, since a previous commit unintentionally masked them (Manivannan Sadhasivam) - Move endpoint controller cleanups that depend on refclk from the host to the notifier that tells us the host has deasserted PERST#, when refclk should be valid (Manivannan Sadhasivam) - Add DT binding and driver support for IPQ9574, with Synopsys IP v5.80a and Qcom IP 1.27.0 (devi priya) - Move the OPP "operating-points-v2" table from the qcom,pcie-sm8450.yaml DT binding to qcom,pcie-common.yaml, where it can be used by other Qcom platforms (Qiang Yu) - Add 'global' SPI interrupt for events like link-up, link-down to qcom,pcie-x1e80100 DT binding so we can start enumeration when the link comes up (Qiang Yu) - Disable ASPM L0s for qcom,pcie-x1e80100 since the PHY is not tuned to support this (Qiang Yu) - Add ops_1_21_0 for SC8280X family SoC, which doesn't use the 'iommu-map' DT property and doesn't need BDF-to-SID translation (Qiang Yu) Rockchip PCIe controller driver: - Define ROCKCHIP_PCIE_AT_SIZE_ALIGN to replace magic 256 endpoint .align value (Damien Le Moal) - When unmapping an endpoint window, compute the region index instead of searching for it, and verify that the address was mapped (Damien Le Moal) - When mapping an endpoint window, verify that the address hasn't been mapped already (Damien Le Moal) - Implement pci_epc_ops.align_addr() for rockchip-ep (Damien Le Moal) - Fix MSI IRQ data mapping to observe the alignment constraint, which fixes intermittent page faults in memcpy_toio() and memcpy_fromio() (Damien Le Moal) - Rename rockchip_pcie_parse_ep_dt() to rockchip_pcie_ep_get_resources() for consistency with similar DT interfaces (Damien Le Moal) - Skip the unnecessary link train in rockchip_pcie_ep_probe() and do it only in the endpoint start operation (Damien Le Moal) - Implement pci_epc_ops.stop_link() to disable link training and controller configuration (Damien Le Moal) - Attempt link training at 5 GT/s when both partners support it (Damien Le Moal) - Add a handler for PERST# signal so we can detect host-initiated resets and start link training after PERST# is deasserted (Damien Le Moal) Synopsys DesignWare PCIe controller driver: - Clear outbound address on unmap so dw_pcie_find_index() won't match an ATU index that was already unmapped (Damien Le Moal) - Use of_property_present() instead of of_property_read_bool() when testing for presence of non-boolean DT properties (Rob Herring) - Advertise 1MB size if endpoint supports Resizable BARs, which was inadvertently lost in v6.11 (Niklas Cassel) TI J721E PCIe driver: - Add PCIe support for J722S SoC (Siddharth Vadapalli) - Delay PCIE_T_PVPERL_MS (100 ms), not just PCIE_T_PERST_CLK_US (100 us), before deasserting PERST# to ensure power and refclk are stable (Siddharth Vadapalli) TI Keystone PCIe controller driver: - Set the 'ti,keystone-pcie' mode so v3.65a devices work in Root Complex mode (Kishon Vijay Abraham I) - Try to avoid unrecoverable SError for attempts to issue config transactions when the link is down; this is racy but the best we can do (Kishon Vijay Abraham I) Miscellaneous: -
