2026-09-30rtc: mt6397: expose the spare bytes of the alarm registers as nvmemRyan Brue
Each alarm field lives in the low bits of its register and the driver masks its writes accordingly, so the high byte of four of them is storage the RTC never touches. MediaTek names these RTC_NEW_SPARE0 to RTC_NEW_SPARE3 and gives the first to a fuel gauge, which is how its PMIC battery drivers carry a state of charge over a reboot. Offer all four as a battery-backed nvmem provider, so that a consumer does not have to reach into this block behind the driver's back. Doing it here is what makes it safe: a write lands under the same lock the alarm paths take, so it can neither be lost inside mtk_rtc_set_alarm()'s read-modify-write nor fire the write trigger in the middle of one. The nvmem core does not range check a cell against the provider size, so the callbacks check the offset themselves. Tested on an MT6397; MediaTek's spare map for mt6323 matches, and the alarm field masks are common to every compatible this driver binds.

2026-09-24mfd: da9150: Balance IRQ wake on teardownMyeonghun Pak
DA9150 enables IRQ wake after registering its regmap IRQ chip, but does not disable it on a later probe failure or driver removal. This leaves the wake depth elevated after the handler is removed, and repeated bind attempts can accumulate the imbalance. Remember whether enabling IRQ wake succeeded and balance only a successful call. Remove MFD children first so their nested IRQ users are gone, then disable wake before removing the regmap IRQ chip. Preserve the existing non-fatal behavior when IRQ wake cannot be enabled. This issue was identified during our ongoing static-analysis research while reviewing kernel code.

2026-09-10mfd: lm3533: Convert to use OF bindingsSvyatoslav Ryhel
Since there are no users of this driver via platform data, remove the platform data support and switch to using Device Tree bindings. Previously, all cell devices were linked to the parent device. This could cause problems further down the line because the LM3533 has multiple cells of the same type. Using a single phandle to the parent could cause confusion when attempting to reference or call the correct child node. Since this commit adds a dedicated node for every cell, remove linking of the cell to the parent node.

2026-06-29regulator: max14577: fix set_mode clobbering enable on MAX77836 LDOsJad Keskes
So the PWRMD field in CNFG1_LDO is both the enable bit and the mode. You can't change one without stepping on the other. The problem is that enable() from the regulator core just writes enable_mask (which is PWRMD_NORMAL). If you'd called set_mode(LPM) then disabled and re-enabled, the mode gets reset to NORMAL. And set_mode updates the register through the same field, so it can accidentally enable a disabled regulator. Fix it by storing the mode in per-regulator data. A custom enable writes whatever mode was last set. set_mode only touches hardware if the regulator is already on; otherwise it just caches the value. Add of_map_mode while here so the initial mode can be wired from DT.

Support for the Motorola EZX phones based on Intel PXA processors was removed in 2022, but this driver remained present in the tree. As far as I can tell, the support was never quite functional upstream because the board files did not actually instantiate the SPI device for the PCAP. There are still also drivers for the various mfd cells: keys, touchscreen, regulator and rtc, all of which are obviously orphaned as well but can be removed separately as the Kconfig dependency now prevents them from being enabled.

2026-06-17mfd: wm8994: Remove dead legacy-gpio codeArnd Bergmann
The old-style gpio handling in wm8994 came from a commit 7c8844481a1c ("mfd: wm8994: Emulate level triggered interrupts if required") in linux-3.11, but nothing in the kernel ever set the 'irq_gpio' member in the wm8994_pdata structure, so this was always dead code. Remove it now to reduce the dependency on the legacy gpio interfaces.

2026-06-17mfd: cs5535: Add, assign and expose the software node for the GPIO cellBartosz Golaszewski
There are board files in-tree that want to request GPIOs from this chip. They currently rely on the GPIO core's mechanism of matching software nodes' labels against GPIO controller names. We want to remove this behavior from the kernel and to this end, we need to associate the referenced GPIO controller with its target software node. Create a dedicated GPIO software node for cs5535, assign it to the GPIO cell and expose its address in a new header. We only expose a single software node instance but that's alright: all existing hardware only contains a single cs5535 companion and the geode board file for which we expose this is legacy anyway.

2026-06-17mfd: sec: Add support for S2MU005 PMICKaustabh Chakraborty
Samsung's S2MU005 PMIC includes subdevices for a charger, an MUIC (Micro USB Interface Controller), and flash and RGB LED controllers. S2MU005's interrupt registers divided into three domains, each for the charger, flash LEDs, and the MUIC, packed into a single regmap IRQ chip construct. In devices other than S2MPG1X, the revision can be retrieved from the first register of the PMIC regmap. In S2MU005 however, the location is in offset 0x73. Introduce a switch-case block to allow selecting the REG_ID register. S2MU005 also has a field mask for the revision. Apply it using FIELD_GET() and get the extracted value. Add initial support for S2MU005 in the PMIC driver, along with its three interrupt chips, and support for allowing to fetch revision based on the device variant.

Therefore, the driver cannot detect the same PMIC of different revisions. (E1/E2 for MT6328, E1/E3 for MT6331/MT6332) Based on these, the CID of MT6328, MT6331 and MT6332 should be corrected. Additionally, the incorrect MT6331/MT6332 CID overlaps with the MT6320's actual CID: #define PMIC6320_E1_CID_CODE 0x1020 #define PMIC6320_E2_CID_CODE 0x2020 This causes a conflict in the switch-case statement of mt6397-irq.c, this prevents adding support for MT6320.

This converts the Arizona driver to use GPIO descriptors exclusively, deletes the legacy code path an updates the in-tree user of legacy GPIO. The GPIO lines for mic detect polarity and headphone ID detection are made exclusively descriptor-oriented. The headphone ID detection could actually only be used by the legacy GPIO code, but I converted it to use a descriptor if someone would actually need it so we don't just drop useful code. The compatible "wlf,hpdet-id-gpio" is not in the device tree bindings and only intended to be used by software nodes if any. If someone insists I can try to add a binding for it, but I doubt there is any real user so it seems pointless.

2026-03-16gpio: kempld: Implement the interrupt controllerAlban Bedel
Add a GPIO IRQ chip implementation for the kempld GPIO controller. Of note is only how the parent IRQ is obtained. The IRQ for the GPIO controller can be configured in the BIOS, along with the IRQ for the I2C controller. These IRQ are returned by ACPI but this information is only usable if both IRQ are configured. When only one is configured, only one is returned making it impossible to know which one it is. Luckily the BIOS will set the configured IRQ in the PLD registers, so it can be read from there instead, and that also work on platforms without ACPI. The vendor driver allowed to override the IRQ using a module parameters, so there are boards in field which used this parameter instead of properly configuring the BIOS. This implementation provides this as well for compatibility.
