video, da8xx-fb: changes for am335x usage
to use this driver also on am335x based boards, the following changes are made: - struct lcd_ctrl_config lcd_cfg is now configurable through board code - controller base is configurable through define DA8XX_LCD_CNTL_BASE. To be compatible with older da8xx based boards: If this define is missing, the DAVINCI_LCD_CNTL_BASE is used - Determine LCD IP Version, and make the driver working on lcd revision register values: Version 1: 0x4C100102 Version 2: 0x4F200800 0x4F201000 Signed-off-by: Heiko Schocher <hs@denx.de> Cc: Stefano Babic <sbabic@denx.de> Cc: Anatolij Gustschin <agust@denx.de> Cc: Tom Rini <trini@ti.com> Acked-by: Tom Rini <trini@ti.com>
