ddeb8d5c1f dt-bindings: display: bridge: renesas,dsi: Document RZ/V2H(P) and RZ/V2N
Add the compatible string "renesas,r9a09g057-mipi-dsi" for the Renesas
RZ/V2H(P) (R9A09G057) SoC. While the MIPI DSI LINK registers are shared
with the RZ/G2L SoC, the D-PHY register layout differs. Additionally, the
RZ/V2H(P) uses only two resets compared to three on RZ/G2L, and requires
five clocks instead of six.

To reflect these hardware differences, update the binding schema to
support the reduced clock and reset requirements for RZ/V2H(P).

Since the RZ/V2N (R9A09G056) SoC integrates an identical DSI IP to
RZ/V2H(P), the same "renesas,r9a09g057-mipi-dsi" compatible string is
reused for RZ/V2N.

3e3169e64e dt-bindings: display: bridge: renesas,dsi: allow properties from dsi-controller
Allow to inherit valid properties from the dsi-controller. This fixes the
following warning when adding a panel property:

rzg2lc.dtb: dsi@10850000: '#address-cells', '#size-cells', 'panel@0' do not
    match any of the regexes: 'pinctrl-[0-9]+'
    from schema $id:
        http://devicetree.org/schemas/display/bridge/renesas,dsi.yaml#

Also add a panel property to the example.

ae5a8dce3c dt-bindings: display: bridge: renesas,rzg2l-mipi-dsi: Document RZ/V2L support
Document RZ/V2L DSI bindings. RZ/V2L MIPI DSI is identical to one found on
the RZ/G2L SoC. No driver changes are required as generic compatible
string "renesas,rzg2l-mipi-dsi" will be used as a fallback.
