This is a 2-patch series adding a new DSI panel driver for the Tianma TA066VVHM03 6.59" AMOLED panel with DSC compression, used in the ASUS ROG Phone 3. The series is clean and follows modern panel driver patterns (uses `devm_drm_panel_alloc`, `mipi_dsi_multi_context`, `drm_connector_helper_get_modes_fixed`, etc.). The DT binding already has a Reviewed-by from Krzysztof Kozlowski.

There are a few issues worth addressing:

1. **Dependency on unmerged `dsc_slice_per_pkt` support** — the cover letter acknowledges this, but it means the driver won't compile on mainline.
2. **Missing cleanup in `prepare()` error paths** — PPS/compression failures leak regulators and GPIOs.
3. **`enable-gpios` mismatch between binding and driver** — optional in binding, mandatory in driver probe.
4. **Questionable LPM handling in `_off()`** — clears LPM before sending DCS commands, which is unusual.
5. **Refresh rate of 160 Hz** looks atypical for a phone panel — may be intentional, but worth confirming.

Overall the series is in reasonable shape. The DT binding patch is fine; the panel driver needs minor fixes to error handling and consistency.
