2014-01-31backlight: Add GPIO-based backlight driverLaurent Pinchart
The GPIO backlight driver controls the backlight in on/off mode through a single GPIO.

commit 185d91442550110db67a7dc794a32efcea455a36 upstream. The driver supports 16-bit brightness values, but the value returned from get_brightness was truncated to eight bits.

2013-11-20backlight: atmel-pwm-bl: fix deferred probe from __initJohan Hovold
commit 9d3fde86b15303decea632c929fbf1f3ae4501f2 upstream. Move probe out of __init section and don't use platform_driver_probe which cannot be used with deferred probing. Since commit e9354576 ("gpiolib: Defer failed gpio requests by default") this driver might return -EPROBE_DEFER if a gpio_request fails.

2013-04-29backlight: lp855x: remove duplicate platform dataKim, Milo
The 'load_new_rom_data' was used for checking whether new ROM data should be updated or not. However, we can decide it with 'size_program' data. If the size is greater than 0, it means updating ROM area is required. Otherwise, the default ROM data will be used. Therefore, this duplicate platform data can be removed.

2013-04-29backlight: lp855x: move backlight mode platform dataKim, Milo
The brightness of LP855x devices is controlled by I2C register or PWM input . This mode was selected through the platform data, but it can be chosen by the driver internally without platform data configuration. How to decide the control mode: If the PWM period has specific value, the mode is PWM input. On the other hand, the mode is register-based. This mode selection is done on the _probe(). Move 'mode' from a header file to the driver private data structure, 'lp855 x'. And correlated code was replaced.

2013-04-29drivers/video/backlight/platform_lcd.c: introduce probe callbackAndrew Bresticker
Platform LCD devices may need to do some device-specific initialization before they can be used (regulator or GPIO setup, for example), but currently the driver does not support any way of doing this. This patch adds a probe() callback to plat_lcd_data which platform LCD devices can set to indicate that device-specific initialization is needed.

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.
