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
