Configure below LCDC configurations to optimal values, also have an option configure these optional parameters for platform. 1) AC bias configuration: Required only for passive panels 2) Dma_burst_size: 3) FIFO_DMA_DELAY: 4) FIFO threshold: Does not apply for da830 LCDC. Patch is verified for 16bpp and 24bpp configurations on da830, da850 and am335x EVMs. Signed-off-by: Manjunathappa, Prakash <prakash.pm@ti.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
