2023-03-16backlight: apple_bl: Use acpi_video_get_backlight_type()Hans de Goede1-0/+1
On some MacBooks both the apple_bl and the apple-gmux backlight drivers may be able to export a /sys/class/backlight device. To avoid having 2 backlight devices for one LCD panel until now the apple-gmux driver has been calling apple_bl_unregister() to move the apple_bl backlight device out of the way when it loads. Similar problems exist on other x86 laptops and all backlight drivers which may be used on x86 laptops have moved to using acpi_video_get_backlight_type() to determine whether they should load or not. Switch apple_bl to this model too, so that it is consistent with all the other x86 backlight drivers. Besides code-simplification and consistency this has 2 other benefits: 1) It removes a race during boot where userspace will briefly see an apple_bl backlight and then have it disappear again, leading to e.g.: https://bbs.archlinux.org/viewtopic.php?id=269920 2) This allows user to switch between the drivers by passing acpi_backlight=apple_gmux or acpi_backlight=vendor on the kernel commandline.

2020-07-01backlight: Delete the OT200 backlight driverLinus Walleij1-7/+0
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.

2013-04-29drivers/video/backlight/Kconfig: fix typo "MACH_SAM9...EK" three timesPaul Bolle1-1/+1
Fix three typos (originally) introduced by commit a9a84c37d1ee ("atmel_lcdfb: backlight control"). Two of these typos were introduced in v2.6.25. (The third was introduced in 915190f7d4f0 ("[ARM] 5614/1: at91: atmel_lcdfb: add at91sam9g10 support to atmel LCD driver")). Checking these commits reveals that the default value of 'y' has never been set automatically in all releases since v2.6.25! Perhaps this line might as well be dropped.

2013-04-16Convert selectors of GENERIC_GPIO to GPIOLIBAlexandre Courbot1-2/+2
GENERIC_GPIO is now equivalent to GPIOLIB and features that depended on GENERIC_GPIO can now depend on GPIOLIB to allow removal of this option. Signed-off-by: Alexandre Courbot <[email protected]> Acked-by: Linus Walleij <[email protected]> Acked-by: Grant Likely <[email protected]>
2013-02-27backlight: add new lp8788 backlight driverKim, Milo1-0/+6
TI LP8788 PMU supports regulators, battery charger, RTC, ADC, backlight dri= ver and current sinks. This patch enables LP8788 backlight module. (Brightness mode) The brightness is controlled by PWM input or I2C register. All modes are supported in the driver. (Platform data) Configurable data can be defined in the platform side. name : backlight driver name. (default: "lcd-backlight") initial_brightness : initial value of backlight brightness bl_mode : brightness control by PWM or lp8788 register dim_mode : dimming mode selection full_scale : full scale current setting rise_time : brightness ramp up step time fall_time : brightness ramp down step time pwm_pol : PWM polarity setting when bl_mode is PWM based period_ns : platform specific PWM period value. unit is nano. The default values are set in case no platform data is defined.
