Subject: [PATCH v2 3/3] ARM: dts: imx6ul/ull: suspend i.MX6UL watchdog in wait mode
Date: Tue, 25 Oct 2022 09:25:33 +0200 [thread overview]
Message-ID: <20221025072533.2980154-4-andrej.picej@norik.com> (raw)
In-Reply-To: <20221025072533.2980154-1-andrej.picej@norik.com>
It was discovered that the watchdog triggers when the device is put into
"Suspend-To-Idle"/"freeze" low-power mode. Setting WDW bit disables
watchdog when the device is put into WAIT mode.
