backlight: pandora-backlight: Use backlight power constants

2024-07-04T15:45:25Z

Replace FB_BLANK_ constants with their counterparts from the backlight subsystem. The values are identical, so there's no change in functionality.

backlight: pandora: Stop using BL_CORE_DRIVER1

2018-04-30T12:25:14Z

Leaking driver internal tracking into the already massively confusing backlight power tracking is really confusing. Stop that by allocating a tiny driver private data structure instead. Signed-off-by: Daniel Vetter Acked-by: Daniel Thompson Reviewed-by: Jani Nikula Signed-off-by: Lee Jones

backlight: Remove .owner field for drivers using module_platform_driver

2014-08-28T13:09:48Z

This patch removes the superflous .owner field for drivers which use the module_platform_driver or platform_driver_register api, as this is overriden in __platform_driver_register. Signed-off-by: Peter Griffin Signed-off-by: Lee Jones

backlight: Remove trivial get_brightness implementations

2014-06-23T12:24:22Z

Since backlight core returns props.brightness in case get_brightness is not implemented trivial implementations are not needed anymore. Acked-by: Jingoo Han Signed-off-by: Andrzej Hajda Signed-off-by: Lee Jones

backlight: add support for Pandora backlight

2012-03-23T23:58:33Z

Add support for pandora (openpandora.org) backlight. It might look like all this could be done using pwm_bl.c instead, but there is a need of special programming sequence when turning on the LED driver chip or else it will misbehave. Doing this using pwm_bl.c would require to use some register programming and pwm functions from platform code, and ARM maintainers are allergic to driver-like code in /arch/arm nowadays. The PMIC PWM driver is currently missing too, so pwm_bl.c can't be used anyway. Signed-off-by: Grazvydas Ignotas Cc: Richard Purdie Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
