Subject: [PATCH v3 3/4] arm64: dts: imx8mq-librem5-devkit: Disable snvs_rtc
Date: Fri,  8 Jan 2021 13:57:09 +0100	[thread overview]
Message-ID: <2a07bf798ee8b7914b127841ac6f4e9b5949fce5.1610110514.git.agx@sigxcpu.org> (raw)
In-Reply-To: <cover.1610110514.git.agx@sigxcpu.org>

The board has it's own RTC chip which is backed by the (optional)
battery and hence preserves data/time on poweroff when that is inserted.
