2010-05-26backlight: add S6E63M0 AMOLED LCD Panel driverInKi Dae
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.

2008-09-23lcd: allow lcd device to handle mode change eventsEric Miao
Some LCD panels are capable of different resolutions, and is allowed to change at run-time, so to make "struct lcd_device" to be able to handle mode change events here.

2008-07-24lcd: add lcd_device to check_fb() entry in lcd_opsBen Dooks
Add the lcd_device being checked to the check_fb entry of lcd_ops. This ensures that any driver using this to check against it's own state can do so, and also makes all the calls in lcd_ops more orthogonal in their arguments.

2007-07-16backlight: Convert from struct class_device to struct deviceRichard Purdie
Convert the backlight and LCD classes from struct class_device to struct device since class_device is scheduled for removal. One nasty API break is the backlight power attribute has had to be renamed to bl_power and the LCD power attribute has had to be renamed to lcd_power since the original names clash with the core. I can't see a way around this. Signed-off-by: Richard Purdie <rpurdie@rpsys.net> Acked-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-02-20backlight: Separate backlight properties from backlight ops pointersRichard Purdie
Per device data such as brightness belongs to the indivdual device and should therefore be separate from the the backlight operation function pointers. This patch splits the two types of data and allows simplifcation of some code. Signed-off-by: Richard Purdie <rpurdie@rpsys.net>

2007-02-20backlight: Fix external uses of backlight internal semaphoreRichard Purdie
backlight_device->sem has a very specific use as documented in the header file. The external users of this are using it for a different reason, to serialise access to the update_status() method. backlight users were supposed to implement their own internal serialisation of update_status() if needed but everyone is doing things differently and incorrectly. Therefore add a global mutex to take care of serialisation for everyone, once and for all. Locking for get_brightness remains optional since most users don't need it. Also update the lcd class in a similar way. Signed-off-by: Richard Purdie <rpurdie@rpsys.net>
2007-02-20backlight: Remove unneeded owner fieldRichard Purdie
Remove uneeded owner field from backlight_properties structure. Nothing uses it and it is unlikely that it will ever be used. The backlight class uses other means to ensure that nothing references unloaded code. Based on a patch from Dmitry Torokhov <dtor@insightbb.com> Signed-off-by: Richard Purdie <rpurdie@rpsys.net>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
