[Aradhya Bhatia <a-bhatia1@ti.com>]

This patch series adds the required support for enabling OLDI display on
boards having SoCs with am625 compatible Display SubSystem.

The 2 OLDI TXes on am625-dss allow a 3 different types of panel
connections with the board.

1. Single Link / Single Mode on OLDI TX 0 OR 1.
2. Single Link / Duplicate Mode on OLDI TX 0 and 1.
3. Dual Link / Single Mode on OLDI TX 0 and 1.

The 3rd combination allows the DSS to be connected to LVDS panels of
resolutions upto 2K.

This patch series further adds support for boards, with HDMI bridges
supporting only 24bit RGB color space, to be able to explicitly output
16bit RGB data when only 16 DPI output pins have been connected from SoC
to bridge.

Note:
These patches require the new compatible "ti,am625-dss" and its support
in tidss driver. Those patches have been previously posted and can be
found on the following link:
