Subject: [PATCH v3 0/3] Apple DWI backlight driver

Apple SoCs come with a 2-wire interface named DWI. On some iPhones, iPads
and iPod touches the backlight controller is connected via this interface.
This series adds a backlight driver for backlight controllers connected
this way.

Changes since v2:
- Add missing includes in driver
- Fix file path in MAINTAINERS

v2: https://lore.kernel.org/asahi/20241207130433.30351-1-towinchenmi@gmail.com/T

Changes since v1:
- Fixed dt-bindings $id.
- Make power-domains an optional property in dt-bindings.
- Added missing error checking after devm_ioremap_resource() in
dwi_bl_probe().

v1: https://lore.kernel.org/asahi/20241206172735.4310-1-towinchenmi@gmail.com/T
