From 243b040c3517093309a41877e3c1c6e8a7540071 Mon Sep 17 00:00:00 2001 From: Jack Zhu Date: Tue, 23 May 2023 16:56:22 +0800 Subject: [PATCH 076/122] media: dt-bindings: cadence-csi2rx: Convert to DT schema Convert DT bindings document for Cadence MIPI-CSI2 RX controller to DT schema format. For compatible, new compatibles should not be messed with conversion, but the original binding did not specify any SoC-specific compatible string, so add the StarFive compatible string.
