pxafb: Add support for other palette formats
This patch adds support for the other three palette formats possible with the PXA LCD controller. This is required on boards where an LCD is connected with all its 18 bits. With this patch, it's possible to use an 8-bit mode with 18-bit palette entries. This used to be possible in 2.4 kernels but disappeared in 2.6. With current kernels, you can only get wrong colours out of an LCD connected this way. Users can choose the palette format by doing something like this in their board definition: static struct pxafb_mach_info my_fb_info = { [...] .lccr3 = LCCR3_OutEnH | LCCR3_PixFlEdg | LCCR3_PDFOR_3, .lccr4 = LCCR4_PAL_FOR_2, [...] }; Signed-off-by: Hans J.
