    backlight: add S6E63M0 AMOLED LCD Panel driver · ee378a5c
    InKi Dae authored
    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.
