[U-Boot] [PATCH v3 0/6] Introduce DCU support for Vybrid

[Sanchayan Maity <maitysanchayan@gmail.com>]

Hello,

This patchset adds support for the Freescale/NXP Display Controller Unit (DCU4)
for Vybrid which is 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.

Changes since v2:
1. Rebase on top of latest u-boot master
2. Drop the fourth patch in earlier series and replace it with a fix for
DCU_MODE_BLEND_ITER and use the existing DCU_LAYER_MAX_NUM instead of
introducing DCU_TOTAL_LAYER_NUM as earlier incoporating Stefan's feedback.

Changes since v1:
1. Rebase of top of latest u-boot master
2. Fix a bug present in v1 patch series which resulted in noisy screen when
switching from u-boot to Linux. Patch fixed is second in this series.

v1:

v2:

Thanks & Regards,
Sanchayan.
