[PATCH v13 2/4] dt-bindings: display: renesas,rzg2l-du: Document RZ/V2L DU bindings

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Document DU found in RZ/V2L SoC. The DU block is identical to RZ/G2L
SoC and therefore use RZ/G2L fallback to avoid any driver changes.
