Pull RTC updates from Alexandre Belloni:
 "We see a net reduction of the number of lines of code thanks to the
  removal of a now unused driver and a testing tool that is not used
  anymore. Apart from this, the max31335 driver gets support for a new
  part number and pm8xxx gets UEFI support.

  Core:

   - setdate is removed as it has better replacements

   - skip alarms with a second resolution when we know the RTC doesn't
     support those.

  Subsystem:

   - remove unnecessary private struct members

   - use devm_pm_set_wake_irq were relevant

  Drivers:

   - ds1307: stop disabling alarms on probe for DS1337, DS1339, DS1341
     and DS3231

   - max31335: add max31331 support

   - pcf50633 is removed as support for the related SoC has been removed

   - pcf85063: properly handle POR failures"

Pull backlight updates from Lee Jones:

 - Apple DWI Backlight:
    - Added devicetree bindings for backlight controllers on Apple's DWI
      interface.
    - Added a new driver (apple_dwi_bl) for these controllers found on
      some Apple mobile devices.
    - Added MAINTAINERS entries for the new driver.

 - led_bl: Fixed a locking issue by holding the led_access lock when
   calling led_sysfs_disable() during device removal to prevent
   potential warnings.

 - Removed unnecessary  includes from a bunch of drivers.

 - tdo24m: Removed redundant whitespace in Kconfig description.

 - pcf50633-backlight: Removed the driver as the underlying pcf50633 MFD
   and s3c24xx platform support were removed.

mfd: pcf50633: Remove remaining PCF50633 support

2025-03-14T11:42:51+00:00

Remove the remaining parts of the 50633, the core, headers and glue.

The pcf50633 was used as part of the OpenMoko devices but
the support for its main chip was recently removed in:
commit 61b7f8920b17 ("ARM: s3c: remove all s3c24xx support")

See https://lore.kernel.org/all/Z8z236h4B5A6Ki3D@gallifrey/

Remove it.
