Subject: [PATCH v3 1/8] watchdog: JZ4740: Disable clock after stopping counter
Date: Thu, 10 May 2018 20:47:44 +0200	[thread overview]
Message-ID: <20180510184751.13416-1-paul@crapouillou.net> (raw)

Previously, the clock was disabled first, which makes the watchdog
component insensitive to register writes.
