* mbp_nvidia_bl: remove DMI dependencyMatthew Garrett2011-03-22
| | | | | | | | | | | | | | | | This driver only has to deal with two different classes of hardware, but right now it needs new DMI entries for every new machine. It turns out that there's an ACPI device that uniquely identifies Apples with backlights, so this patch reworks the driver into an ACPI one, identifies the hardware by checking the PCI vendor of the root bridge and strips out all the DMI code. It also changes the config text to clarify that it works on devices other than Macbook Pros and GPUs other than nvidia.

* backlight: add S6E63M0 AMOLED LCD Panel driverInKi Dae2010-05-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is S6E63M0 AMOLED LCD Panel(480x800) driver using 3-wired SPI interface also almost features for lcd panel driver has been implemented in here. and I added new structure common for all the lcd panel drivers to include/linux/lcd.h file. LCD Panel driver needs interfaces for controlling device power such as power on/off and reset. these interfaces are device specific so it should be implemented to machine code at this time, we should create new structure for registering these functions as callbacks and also a header file for that structure and finally registered callback functions would be called by lcd panel driver. such header file(including new structure for lcd panel) would be added for all the lcd panel drivers. If anyone provides common structure for registering such callback functions then we could reduce unnecessary header files for lcd panel. I thought that suitable anyone could be include/linux/lcd.h so a new lcd_platform_data structure was added there.

Unfortunately Datasheet for this device are not available and all the control sequences sent to the display were copied from the freescale driver that in the i.MX31 Linux BSP.

Expose this functionality via the backlight API. Since when used in this configuration the current sink and boost convertor are very tightly coupled with a multi-stage startup for the current sink which overlaps with the boost convertor startup this driver bypasses the regulator API. Machine inititialisation is responsible for ensuring that the regulators are not accessed via both APIs.

This patch lets boards declare that they have that kind of backlight control. The driver can then export this control, letting screenblank and other operations actually take effect ... reducing the typically substantial power drain from the backlight. Note that it's not fully cooked - doesn't force backlight off during system suspend - the "power" and "blank" events may not be done right This should be easily added in the future.

* [PATCH] backlight: corgi_bl: Generalise to support other Sharp SL hardwareRichard Purdie2006-03-31
| | | | | | | | | | | | | | Generalise the Corgi backlight driver by moving the default intensity and limit mask settings into the platform specific data structure. This enables the driver to support other Zaurus hardware, specifically the SL-6000x (Tosa) model. Also change the spinlock to a mutex (the spinlock is overkill).
