This is a well-structured 16-patch series from Tomi Valkeinen adding display support for the BeagleY-AI board (TI AM62P/J722S SoCs). The series covers DT bindings, driver changes, and board DTS. The main highlights:

1. **DT binding refactoring** (patches 1-5): Splits AM62L into its own binding file, simplifies the AM65x binding, adds OLDI power-domain, adds `ti,dpi-io-ctrl` for signal edge config, and adds AM62P DSS compatible.

2. **Driver cleanups** (patches 6-7): Removes redundant `pm_runtime_mark_last_busy` and unused OLDI register define.

3. **DPI detection and signal edge support** (patches 8-10): Adds mechanism to detect DPI output, configures external DPI0_CLK_CTRL register via syscon, and adds DPIENABLE bit support for power savings.

4. **OLDI fixes and aux driver conversion** (patches 11-12): Fixes signal polarity handling, then converts OLDI to auxiliary device/driver for proper power-domain management.

5. **AM62P support and board DTS** (patches 13-16): Adds AM62P compatible, makes main_conf a syscon, adds DSS/OLDI/DSI/DPHY nodes, enables HDMI on BeagleY-AI.

Overall the series is solid work with good commit messages explaining the "why". Most DT binding patches already have Rob's Reviewed-by. A few issues worth addressing are noted below.
