[PATCH v2 04/20] dt-bindings: watchdog: Document Google gs101 & gs201 watchdog bindings

Subsystem:
open firmware and flattened device tree bindings, the rest, watchdog device drivers · Maintainers:

Add the "google,gs101-wdt" and "google,gs201-wdt" compatibles 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.
