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]
