| Series | Apple DWI backlight driver | expand |
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 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 Nick Chan --- Nick Chan (3): dt-bindings: leds: backlight: apple,dwi-bl: Add bindings for Apple DWI backlight backlight: dwi_bl: Add Apple DWI backlight driver MAINTAINERS: Add entries for Apple DWI backlight controller .../bindings/leds/backlight/apple,dwi-bl.yaml | 54 ++++++++ MAINTAINERS | 2 + drivers/video/backlight/Kconfig | 12 ++ drivers/video/backlight/Makefile | 1 + drivers/video/backlight/dwi_bl.c | 124 ++++++++++++++++++ 5 files changed, 193 insertions(+) create mode 100644 Documentation/devicetree/bindings/leds/backlight/apple,dwi-bl.yaml create mode 100644 drivers/video/backlight/dwi_bl.c base-commit: 40384c840ea1944d7c5a392e8975ed088ecf0b37
