video: backlight: mt6370: Add MediaTek MT6370 support

2022-09-08T07:50:57Z

MediaTek MT6370 is a SubPMIC consisting of a single cell battery charger with ADC monitoring, RGB LEDs, dual channel flashlight, WLED backlight driver, display bias voltage supply, one general purpose LDO, and the USB Type-C & PD controller complies with the latest USB Type-C and PD standards. Add support for the MediaTek MT6370 backlight driver. It controls 4 channels of 8 series WLEDs in 2048 (only for MT6370/MT6371) / 16384 (only for MT6372) current steps (30 mA) in exponential or linear mapping curves.

backlight: Add Kinetic KTD253 backlight driver

2020-08-28T10:48:04Z

The Kinetic KTD253 backlight driver is controlled with a single GPIO line, but still supports a range of brightness settings by sending fast pulses on the line. This is based off the source code release for the Samsung GT-S7710 mobile phone. Cc: Sam Ravnborg Reviewed-by: Daniel Thompson Signed-off-by: Linus Walleij Signed-off-by: Lee Jones

backlight: generic_bl: Remove this driver as it is unused

2020-07-20T09:26:08Z

The backlight_bl driver required initialization using struct generic_bl_info. As there are no more references to this struct there is no users left. So it is safe to delete the driver. Signed-off-by: Sam Ravnborg Reviewed-by: Daniel Thompson Reviewed-by: Emil Velikov Signed-off-by: Lee Jones

backlight: Delete the OT200 backlight driver

2020-07-01T09:55:56Z

This driver has no in-kernel users. The device can only be populated by board files since it does not support device tree nor ACPI, and nothing in the kernel creates a device named "ot200-backlight". This driver has been in the kernel since 2012. If it is used by out-of-tree code that code should have been upstreamed by now, it's been 8 years. It uses the idiomatic forked GPIO of the CS5535 which combines pin control and GPIO into its private custom interface, which causes me a headache because that is not how we do things these days: we creates separate pin control and GPIO drivers. Delete this unused driver. Cc: Christian Gmeiner Signed-off-by: Linus Walleij Reviewed-by: Daniel Thompson Signed-off-by: Lee Jones

backlight: add led-backlight driver

2020-02-19T21:15:39Z

This patch adds a led-backlight driver (led_bl), which is similar to pwm_bl except the driver uses a LED class driver to adjust the brightness in the HW. Multiple LEDs can be used for a single backlight.
