This is a 21-patch series adding DU (Display Unit) and MIPI DSI support for the Renesas RZ/G3E SoC. It spans clock drivers, DT bindings, DRM driver extensions, media bindings, and device tree nodes. The series is well-structured with a logical progression: clock infrastructure first (patches 1-8), then bindings (9-11, 16-17), driver support (12-15), and finally DTS nodes (18-21).

The clock patches are straightforward and mostly have Reviewed-by tags from Geert Uytterhoeven. The DRM patches introduce a novel mechanism for selecting clock paths via duty cycle manipulation, which is clever but somewhat unusual.

There are several issues ranging from a clear indentation/coding bug to architectural concerns about the input port discovery logic in the DSI driver.
