Replace by more specific (c files)

2026-07-03T05:38:17+00:00

Replace the #include of by the more specific where applicable. For most cases the include can be dropped completely, only a few drivers need one or two headers added.

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: rohm-bd718x7: Use software nodes for gpio-keys

2026-07-01T20:24:28+00:00

Refactor the rohm-bd7182x7 MFD driver to use software nodes for instantiating the gpio-keys child device, replacing the old platform_data mechanism. The power key's properties are now defined using software nodes and property entries. The IRQ is passed as a resource attached to the platform device. This will allow dropping support for using platform data for configuring gpio-keys in the future.

mfd: axp20x: Preserve other control bits when powering off

2026-07-01T20:24:25+00:00

axp20x_power_off() triggers shutdown by writing AXP20X_OFF (BIT(7)) to the power-off control register with regmap_write(), which rewrites the whole register and clears other control bits in it. On the AXP221/AXP223 (and the register-compatible AXP228) - that register also holds the CHGLED auto-control bit. Clearing it during an orderly shutdown disables the hardware charge indicator, so the charge LED stays dark while the board is powered off and charging. Other variants keep unrelated configuration in the same register too. Set only the power-off bit with regmap_set_bits() and leave the rest of the register untouched. The shutdown register is readable on every variant, so the read-modify-write should be safe. Tested on a ClockworkPi uConsole (Raspberry Pi Compute Module 4, AXP228, which enumerates as AXP221): register AXP20X_OFF_CTRL reads 0x08 at runtime, so the old code left it 0x80 whereas setting only BIT(7) leaves 0x88. Writing 0x88 at power-off enables the charge LED while still powering off the PMIC.

mfd: ipaq-micro: Fix out-of-bounds stack read in ipaq_micro_str

2026-07-01T20:24:22+00:00

ipaq_micro_str() decodes a UTF-16LE string into an ASCII string. It copies characters to a stack buffer retstr, but fails to null-terminate it. When kstrdup() is called on retstr, it can read past the buffer into uninitialized stack memory, potentially leaking stack contents. Fix this by initializing retstr to zero.

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.
