[ARM] 4352/1: AT91: Platform data for LCD and AC97.
Browse files Browse the repository at this point in the history 
Define resources, platform_device and device registration functions for
the LCD and AC97 controllers on the AT91SAM9263.
Also update the AT91SAM9261 to use the common atmel_lcdfb driver.
