Hi All,

This series adds support for the Display Unit (DU) on the RZ/T2H
and RZ/N2H (R9A09G087) SoCs. The DU on these platforms is
functionally similar to the RZ/G2UL DU but includes some SoC
specific differences such as a single output port and explicit
DPI output enable control. The series includes the following
changes:
1. Add device tree bindings for the RZ/T2H and RZ/N2H DU variants,
   including a new compatible string and port property.
2. Make the DU reset control optional to allow probing on RZ/T2H
   where the DU does not have a reset line.
3. Move pixel clock validation logic to per-SoC constraints in
   rzg2l_du_device_info to accommodate different clock limits
   across SoCs.
4. Implement support for the RZ/T2H DU variant in the driver,
   including handling of the DPI output enable signal.

Patches are rebased on next-20260429 and apply on drm-next.

Cheers,
Prabhakar
