From a5032991e108f88ac8a69452b24fa9c8b4621352 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Tue, 8 Feb 2022 18:18:21 +0100 Subject: [PATCH] dt-bindings: display: samsung,exynos-hdmi: convert to dtschema Convert the Exynos HDMI bindings to DT schema format. The conversion includes also updates to the bindings, matching the current DTS and Linux driver: 1. Add required properties: VDD supplies, power-domains. 2. Add optional properties: HDMI-EN supply, ports.
