Hello,
This patchset adds support for the Freescale/NXP Display
Controller Unit (DCU4) found on the LS1021A and Vybrid
SoC.
Patch series is based on top of latest u-boot master.
First patch in the series renames existing CONFIG_FSL_DCU_FB
to CONFIG_VIDEO_FSL_DCU_FB and then converts it to Kconfig.
All board defconfigs affected by this patch have been compile
tested.
Patch 2-5 introduce incremental changes for supporting DCU
on Vybrid.
Patch 6 in the series adds DCU support to Vybrid and has been
tested on Toradex Colibri VF61 module.
Will appreciate it if the maintainers or users of LS1021 SoC
can test this to check and report regressions if any.
Thanks & Regards,
Sanchayan.

The test mode immediately shows a red screen on a LCD. A moment later, the DCU gets initialized properly. This patch enables the pixel clock after initialization of the DCU control register. This avoids this initial flicker on LCD screens. While at it change the polarity of pixel clock to display samples data on the rising edge.
