    ARM: at91/avr32/atmel_lcdfb: add platform device-id table · bbd44f6b
    Johan Hovold authored
    Add platform device-id table in order to identify the controller and
    determine its configuration.
    
    The currently used configuration parameters are:
    
    have_alt_pixclock
     - SOC uses an alternate pixel-clock calculation formula (at91sam9g45
       non-ES)
    
    have_hozval
     - SOC has a HOZVAL field in LCDFRMCFG which is used to determine the
       linesize for STN displays (at91sam9261, at921sam9g10 and at32ap)
    
    have_intensity_bit
     - SOC uses IBGR:555 rather than BGR:565 16-bit pixel layout
       (at91sam9261, at91sam9263 and at91sam9rl)
    
    This allows us to remove all the remaining uses of cpu_is macros from
    the driver.
    
    Tested on at91sam9263 and at91sam9g45, compile-tested for other
    AT91-SOCs, and untested for AVR32.
