From b5acc262278f679bfb7479f817423180096acb8b Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Wed, 8 Nov 2023 11:43:43 +0100 Subject: arm64: dts: exynosautov9: add specific compatibles to several blocks ExynosAutov9 reuses several devices from older designs, thus historically we kept the old (block's) compatible only. This works fine and there is no bug here, however guidelines expressed in Documentation/devicetree/bindings/writing-bindings.rst state that: 1. Compatibles should be specific. 2. We should add new compatibles in case of bugs or features. Add compatibles specific to ExynosAutov9 in front of all old-SoC-like compatibles. This will also help reviews of new code using existing DTS as template. No functional impact on Linux drivers behavior.
