Hi All,

This patch series adds support for the Display Unit (DU) and MIPI DSI
interface on the Renesas RZ/V2H(P) SoC. The inital patches add PLLDSI
clocks and reset entries for the DSI and LCDC and the later patches add
support for the DU and DSI drivers. The DU block is similar to the
RZ/G2L SoC, but the DSI interface is slightly different. The patches
include updates to the device tree bindings, clock and reset
controllers, and the DU driver to accommodate these changes.

Note, my initail intention was to split the clock patches and the DU/DSI
driver patches into two separate series. However, I found that sending
them together will make it easier for the reviewers to understand clock
related changes.

Note, the clock patches aplly on top of the following patch series:

Cheers,
Prabhakar
