From 4d1363a46cdfcc00460adf1f0fcb81bb5ba69d94 Mon Sep 17 00:00:00 2001 From: AngeloGioacchino Del Regno Date: Fri, 7 Oct 2022 17:34:34 +0800 Subject: dt-bindings: watchdog: mediatek: Convert mtk-wdt to json-schema MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Convert the MediaTek watchdog bindings to schema. The original binding only had 4 without a fallback but there is a reset controller on the "mediatek,mt7986-wdt", "mediatek,mt8186-wdt", "mediatek,mt8188-wdt" and "mediatek,mt8195-wdt" Since there is no reset controller for the mt6589, we remove "mediatek,mt6589-wdt" as a fallback.
