[U-Boot] [PATCH v3 1/2] mx6sabresd: Allow probing HSYNC, VSYNC and DISP_CLK signals

[U-Boot] [PATCH v3 1/2] mx6sabresd: Allow probing HSYNC, VSYNC and DISP_CLK signals

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam@freescale.com>

HSYNC, VSYNC and DISP_CLK are very useful display signals for debugging.

Configure them as active pins.

Changes since v2:
- Fix typo in HSYNC
Changes since v1:
- Add a comment in the code explaining that the purpose of configuring these
pins are for debugging

[U-Boot] [PATCH v3 2/2] mx6sabresd: Fix LVDS width and color format

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam@freescale.com>

mx6sabresd boards have a 18-bit LVDS data width and the correct color format
is RGB666.
