[PATCH v2 2/3] dt-bindings: watchdog: Add missing clocks requirement in Samsung SoC watchdog

From: Krzysztof Kozlowski
Date: Fri Sep 20 2019 - 12:21:49 EST


The Samsung SoC watchdog driver always required providing a clock
(either through platform data or from DT). However when bindings were
added in commit 9487a9cc7140 ("watchdog: s3c2410: Add support for device
tree based probe"), they missed the requirement of clock.

Changes since v1:
1. Indent example with four spaces (more readable),
2. Add also missing required entries for clocks.
