This is a 5-patch series adding GPU device tree nodes for TI K3 SoCs (J721E, J784S4, J722S/AM62P) to enable the Imagination/PowerVR GPU driver, plus a clock framework fix. The series is authored by Antonios Christidis (TI) and includes two patches originally from Michael Walle.

**Overall assessment: Needs minor revisions.** The patches are straightforward DTS additions with reasonable content, but there are ordering issues, a missing blank line in the binding patch, inconsistencies between the DTS nodes across patches, and a vague subject line.

**Key concerns:**
1. **Patch ordering**: The DT binding (patch 2) should come *before* the DTS that uses the new compatible (patch 1), per kernel convention.
2. **Inconsistencies** across DTS nodes: patch 4 is missing `assigned-clocks`/`assigned-clock-rates` and `dma-coherent` compared to patches 1 and 3. This may be intentional but needs clarification.
3. **Patch 5 (clock fix)** is a functional fix that other patches depend on and arguably belongs at the start of the series or in a separate submission.
4. Missing `status = "disabled"` on all GPU nodes -- if the convention for this platform is to leave nodes disabled and enable per-board, this should be added.
