Add ATMEL LCD driver
This patch adds support for the ATMEL LCDC driver which is used on some AT91 and AVR platforms. Is has been tested with the AT91CAP9ADK, AT91SAM9261EK, AT91SAM9263EK and AT91SAM9RLEK boards. Adaptation for AVR32 should probably be easy. Signed-off-by: Stelian Pop <stelian@popies.net> Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>
