Re: [U-Boot] [PATCH v3 1/2] drivers/video/am335x-fb: Add support for 16bpp format

To support 16bpp we just need to change the raster_ctrl register accordingly. Also 32bpp mode should work as well, but was not tested. According to the TRM the uppermost byte will be ignored when LCD_TFT_24BPP_UNPACK is set.

The switch logic is based on the Liunx kernel tilcdc driver: drivers/gpu/drm/tilcdc/tilcdc_crtc.c: lines 407 through 419 (kernel was checked out at commit: bcc981e9ed8)

Changes in v3:

• Moved switch statement before changing any registers
