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.[akpm@linux-foundation.org: coding-style fixes]

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.Signed-off-by: Eric Miao

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.Signed-off-by: Ben Dooks

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

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

Convert internal semaphore to a mutex
Signed-off-by: Richard 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.

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

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!
