From ed6a6d63513ee5199841c0a0dc2772ad944e63ee Mon Sep 17 00:00:00 2001 From: Lad Prabhakar Date: Mon, 12 May 2025 19:23:19 +0100 Subject: [PATCH] dt-bindings: display: renesas,rzg2l-du: Add support for RZ/V2H(P) SoC The DU block on the RZ/V2H(P) SoC is identical to the one found on the RZ/G2L SoC. However, it only supports the DSI interface, whereas the RZ/G2L supports both DSI and DPI interfaces. Due to this difference, a SoC-specific compatible string 'renesas,r9a09g057-du' is added for the RZ/V2H(P) SoC.
