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 v3:
- $ref to common.yaml in bindings
- (and then additionalProperties is changed to unevaluatedProperties)
- Use hex everywhere in bindings example
- Use sizeof(*dwi_bl) instead of the type of the struct when doing
devm_kzalloc()
- Use devm_platform_get_and_ioremap_resource() in driver
- Fix sorting in drivers/video/backlight/Makefile
- In drivers/video/backlight/Kconfig, move config to right after
BACKLIGHT_APPLE
- Explain this driver being completely different from apple_bl
v3: https://lore.kernel.org/asahi/20241209075908.140014-1-tow...
Changes since v2:
- Add missing includes in driver
- Fix file path in MAINTAINERS
v2: https://lore.kernel.org/asahi/20241207130433.30351-1-towi...
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().
