Subject: [PATCH 1/2] ARM: dts: vf610-zii: Disable SNVS RTC
Date: Tue, 12 Feb 2019 23:45:48 -0200	[thread overview]
Message-ID: <20190213014549.29283-1-festevam@gmail.com> (raw)

None of these vf610-zii boards have a battery or super-capacitor
holding up power to the SNVS RTC embedded in the Vybrid SoC,
so it is preferable to disable the snvsrtc node.
