Subject: dt-bindings: display: renesas,rzg2l-du: Add support for RZ/V2N SoC
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=e96a7dc6de5f6c2cac8cc919584c95ae52cf1f9a;p=thirdparty%2Fkernel%2Flinux.git

dt-bindings: display: renesas,rzg2l-du: Add support for RZ/V2N SoC

Document support for the DU IP found on the Renesas RZ/V2N (R9A09G056) SoC.
The DU IP is functionally identical to that on the RZ/V2H(P) SoC, so no
driver changes are needed. The existing `renesas,r9a09g057-du` compatible
will be used as a fallback for the RZ/V2N SoC.
