mfd: 88pm886: Initialize the battery page

2026-07-01T20:24:34+00:00

Initialize the PMIC's battery page. The battery page registers are shared between Vbus regulator, charger, fuelgauge and camera flash blocks, hence the commonization of the page.

mfd: cs42l43: Use new SoundWire enumeration helper

2026-07-01T20:24:32+00:00

Now the new wait for SoundWire enumeration helper no longer depends on unattach_request it is safe to use from probe time. Update the driver to use the new core helper.

mfd: si476x: Modernize GPIO handling

2026-07-01T20:24:21+00:00

The SI476X driver depends on the legacy GPIO API. As it only really use a single GPIO for reset, and this can be easily converted to use a GPIO descriptor, modernize the driver. The "reset" GPIO is obtained from a device property, such as a device tree ("reset-gpios", which is standard, but this hardware has no DT bindings as of now) or a software node for static platforms. Out-of-tree users can easily adopt to providing a GPIO descriptor this way.

regulator: max14577: fix set_mode clobbering enable on MAX77836 LDOs

2026-06-29T17:59:47+00:00

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.

mfd: ezx-pcap: Remove unused driver

2026-06-17T10:32:14+00:00

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.

mfd: max77759: Improve static struct formatting and commentary

2026-06-17T10:32:03+00:00

Improve code style. This includes the following: - Formatting the max77759_chgr_irqs entries to fit in a single line instead of breaking them into multiple lines to improve readability. - Refactoring comments such that they're full sentences and have punctuation marks for a couple of macro definitions to adhere to the documentation style. - Explicitly initializing `MAX77759_CHGR_MODE_OFF`.

mfd: wm8994: Remove dead legacy-gpio code

2026-06-17T10:32:00+00:00

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.

mfd: cs5535: Add, assign and expose the software node for the GPIO cell

2026-06-17T10:31:55+00:00

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.

mfd: bq257xx: Add BQ25792 support

2026-06-17T10:30:35+00:00

Add register definitions and a new 'type' enum to be passed via MFD private data to support the BQ25792, which is a newer variant of the BQ257xx family. BQ25792 shares similar logic of operation with the already supported BQ25703A but has a completely different register map and different electrical constraints.
