[PATCH v4 0/3] Add Display support for AM62P SoC

[Swamil Jain <s-jain1@ti.com>]

Display Controller Overview:
TI's AM62P[1] SoC has two instances of TI's Display Subsystem (DSS).
Each instance contains two video ports. Combined, both instances support
up to three independent video streams: OLDI, DPI, and DSI.

This series:
  1. Updates bindings (PATCH 1/3)
    - Adds "ti,am62p-dss" compatible string
    - Modifies power-domain requirements
  2. Updates driver (PATCH 2/3 and 3/3)
    - Adds power management for attached PM domains
    - Enables AM62P DSS support by adding compatible to the driver

Note:
  - Device-tree changes will be submitted after this series is merged.  
  - The device-tree patches are available here[2]
