From 81306efd22fff7eecf4e62919283dd27111f0173 Mon Sep 17 00:00:00 2001 From: Peter Griffin Date: Mon, 11 Dec 2023 16:23:16 +0000 Subject: dt-bindings: watchdog: Document Google gs101 watchdog bindings Add the "google,gs101-wdt" compatible to the dt-schema documentation. gs101 SoC has two CPU clusters and each cluster has its own dedicated watchdog timer (similar to exynos850 and exynosautov9 SoCs). These WDT instances are controlled using different bits in PMU registers.
