2024-09-22Input: hynitron_cstxxx - drop explicit initialization of struct ↵Uwe Kleine-König
i2c_device_id::driver_data to 0 These drivers don't use the driver_data member of struct i2c_device_id, so don't explicitly initialize this member. This prepares putting driver_data in an anonymous union which requires either no initialization or named designators. But it's also a nice cleanup on its own.

2024-09-20Input: adp5588-keys - fix check on return codeNuno Sa
During adp5588_setup(), we read all the events to clear the event FIFO. However, adp5588_read() just calls i2c_smbus_read_byte_data() which returns the byte read in case everything goes well. Hence, we need to explicitly check for a negative error code instead of checking for something different than 0.

git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull SoC driver updates from Arnd Bergmann: "The driver updates seem larger this time around, with changes is many of the SoC specific drivers, both the custom drivers/soc ones and the closely related subsystems (memory, bus, firmware, reset, ...). The at91 platform gains support for sam9x7 chips in the soc and power management code. This is the latest variant of one of the oldest still supported SoC families, using the ARM9 (ARMv5) core. As usual, the qualcomm snapdragon platform gets a ton of updates in many of their drivers to add more features and additional SoC support. Most of these are somewhat firmware related as the platform has a number of firmware based interfaces to the kernel. A notable addition here is the inclusion of trace events to two of these drivers. Herve Codina and Christophe Leroy are now sending updates for drivers/soc/fsl/ code through the SoC tree, this contains both PowerPC and Arm specific platforms and has previously been problematic to maintain. The first update here contains support for newer PowerPC variants and some cleanups. The turris mox firmware driver has a number of updates, mostly cleanups. The Arm SCMI firmware driver gets a major rework to modularize the existing code into separately loadable drivers for the various transports, the addition of custom NXP i.MX9 interfaces and a number of smaller updates. The Arm FF-A firmware driver gets a feature update to support the v1.2 version of the specification. The reset controller drivers have some smaller cleanups and a newly added driver for the Intel/Mobileye EyeQ5/EyeQ6 MIPS SoCs. The memory controller drivers get some cleanups and refactoring for Tegra, TI, Freescale/NXP and a couple more platforms.

2024-09-16Merge tag 'vfs-6.12.file' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs Pull vfs file updates from Christian Brauner: "This is the work to cleanup and shrink struct file significantly. Right now, (focusing on x86) struct file is 232 bytes. After this series struct file will be 184 bytes aka 3 cacheline and a spare 8 bytes for future extensions at the end of the struct. With struct file being as ubiquitous as it is this should make a difference for file heavy workloads and allow further optimizations in the future. - struct fown_struct was embedded into struct file letting it take up 32 bytes in total when really it shouldn't even be embedded in struct file in the first place. Instead, actual users of struct fown_struct now allocate the struct on demand. This frees up 24 bytes. - Move struct file_ra_state into the union containg the cleanup hooks and move f_iocb_flags out of the union. This closes a 4 byte hole we created earlier and brings struct file to 192 bytes. Which means struct file is 3 cachelines and we managed to shrink it by 40 bytes. - Reorder struct file so that nothing crosses a cacheline. I suspect that in the future we will end up reordering some members to mitigate false sharing issues or just because someone does actually provide really good perf data. - Shrinking struct file to 192 bytes is only part of the work. Files use a slab that is SLAB_TYPESAFE_BY_RCU and when a kmem cache is created with SLAB_TYPESAFE_BY_RCU the free pointer must be located outside of the object because the cache doesn't know what part of the memory can safely be overwritten as it may be needed to prevent object recycling. That has the consequence that SLAB_TYPESAFE_BY_RCU may end up adding a new cacheline. So this also contains work to add a new kmem_cache_create_rcu() function that allows the caller to specify an offset where the freelist pointer is supposed to be placed. Thus avoiding the implicit addition of a fourth cacheline. - And finally this removes the f_version member in struct file. The f_version member isn't particularly well-defined. It is mainly used as a cookie to detect concurrent seeks when iterating directories. But it is also abused by some subsystems for completely unrelated things. It is mostly a directory and filesystem specific thing that doesn't really need to live in struct file and with its wonky semantics it really lacks a specific function. For pipes, f_version is (ab)used to defer poll notifications until a write has happened. And struct pipe_inode_info is used by multiple struct files in their ->private_data so there's no chance of pushing that down into file->private_data without introducing another pointer indirection. But pipes don't rely on f_pos_lock so this adds a union into struct file encompassing f_pos_lock and a pipe specific f_pipe member that pipes can use. This union of course can be extended to other file types and is similar to what we do in struct inode already" * tag 'vfs-6.12.file' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: (26 commits) fs: remove f_version pipe: use f_pipe fs: add f_pipe ubifs: store cookie in private data ufs: store cookie in private data udf: store cookie in private data proc: store cookie in private data ocfs2: store cookie in private data input: remove f_version abuse ext4: store cookie in private data ext2: store cookie in private data affs: store cookie in private data fs: add generic_llseek_cookie() fs: use must_set_pos() fs: add must_set_pos() fs: add vfs_setpos_cookie() s390: remove unused f_version ceph: remove unused f_version adi: remove unused f_version mm: Removed @freeptr_offset to prevent doc warning ...
2024-09-13Input: i8042 - add TUXEDO Stellaris 15 Slim Gen6 AMD to i8042 quirk tableWerner Sembach
The Gen6 devices have the same problem and the same Solution as the Gen5 ones. Some TongFang barebones have touchpad and/or keyboard issues after suspend, fixable with nomux + reset + noloop + nopnp. Luckily, none of them have an external PS/2 port so this can safely be set for all of them. I'm not entirely sure if every device listed really needs all four quirks, but after testing and production use, no negative effects could be observed when setting all four.

of_property_present() There's no need to get the length of an DT array property before parsing the array. of_property_read_variable_u32_array() takes a minimum and maximum length and returns the actual length (or error code).

If devm_add_action() fails we are explicitly calling the cleanup to free the resources allocated. Lets use the helper devm_add_action_or_reset() and return directly in case of error, as we know that the cleanup function has been already called by the helper if there was any error.

Some TongFang barebones have touchpad and/or keyboard issues after suspend, fixable with nomux + reset + noloop + nopnp. Luckily, none of them have an external PS/2 port so this can safely be set for all of them. I'm not entirely sure if every device listed really needs all four quirks, but after testing and production use, no negative effects could be observed when setting all four.

2024-09-02Merge tag 'scmi-updates-6.12' of ↵Arnd Bergmann
https://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/drivers Arm SCMI updates for v6.12 Few main features include: 1. SCMI transport as stand-alone drivers Currently the SCMI transport layer is being built embedded into in the core SCMI stack. Some of these transports, despite being currently part of the main SCMI module, are indeed also registered with different subsystems like optee or virtio, and actively probed also by those. This leads to a few awkward and convoluted tricks to properly handle such interactions at boot time in the SCMI stack. This change adds the new logic to the core SCMI stack so that each existing transport is transitioned to be a standi-alone driver. With that all the probe deferral and awkward retries between the SCMI core stack and the transports has been removed, since no more needed. 2. Support for obtaining transport descriptors from the devicetree SCMI platform firmwares might have different designs depending on the platform. Some of the transport descriptors rely on such design. E.g. the maximum receive channel timeout value might vary depending on the specific underlying hardware and firmware design choices. This change adds support for max-rx-timeout-ms property to describe the transport needs of a specific platform design. It will be extended in the future to obtain other such hardware/firmware dependent transport related descriptors. 3. NXP i.MX95 specific SCMI vendor protocol extensions SCMI specification allows vendor or platform-specific extensions to the interface. NXP i.MX95 System Manager(SM) that implements SCMI extends the interface to implement couple of vendor/platform specific protocol, namely: a. Battery Backed Module(BBM) Protocol This protocol is intended provide access to the battery-backed module. This contains persistent storage (GPR), an RTC, and the ON/OFF button. The protocol can also provide access to similar functions implemented via external board components. b. MISC Protocol for misc settings This includes controls that are misc settings/actions that must be exposed from the SM to agents. They are device specific and are usually define to access bit fields in various mix block control modules, IOMUX_GPR, and other GPR/CSR owned by the SM. 4. SCMI debug/tracking metrics Since SCMI involves interaction with the entity(software, firmware and/or hardware) providing services or features, it is quite useful to track certain metrics(for pure debugging purposes) like how many messages were sent or received, were there any failures, what kind of failures, ..etc. This feature adds support for the same via debugfs. Apart from these main features, there are some miscellaneous updates, fixes and cleanups. * tag 'scmi-updates-6.12' of https://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: (31 commits) rtc: support i.MX95 BBM RTC input: keyboard: support i.MX95 BBM module firmware: imx: Add i.MX95 MISC driver firmware: arm_scmi: Add initial support for i.MX MISC protocol firmware: arm_scmi: Add initial support for i.MX BBM protocol firmware: arm_scmi: Add NXP i.MX95 SCMI documentation dt-bindings: firmware: Add i.MX95 SCMI Extension protocol firmware: arm_scmi: Replace comma with the semicolon firmware: arm_scmi: Replace the use of of_node_put() to __free(device_node) firmware: arm_scmi: Fix trivial whitespace/coding style issues firmware: arm_scmi: Use max-rx-timeout-ms from devicetree dt-bindings: firmware: arm,scmi: Introduce property max-rx-timeout-ms firmware: arm_scmi: Remove const from transport descriptors firmware: arm_scmi: Simplify with scoped for each OF child loop firmware: arm_scmi: Update various protocols versions firmware: arm_scmi: Remove legacy transport-layer code firmware: arm_scmi: Make VirtIO transport a standalone driver firmware: arm_scmi: Make OPTEE transport a standalone driver firmware: arm_scmi: Make SMC transport a standalone driver firmware: arm_scmi: Make MBOX transport a standalone driver ...
