davinci: fb: Frame Buffer driver for TI DA8xx/OMAP-L1xx
Add LCD controller (LCDC) driver for TI's DA8xx/OMAP-L1xx architecture. LCDC specifications can be found at http://www.ti.com/litv/pdf/sprufm0a. LCDC on DA8xx consists of two independent controllers, the Raster Controller and the LCD Interface Display Driver (LIDD) controller. LIDD further supports character and graphic displays. This patch adds support for the graphic display (Sharp LQ035Q3DG01) found on the DA830 based EVM. The EVM details can be found at: http://support.spectrumdigital.com/boards/dskda830/revc/.
