Subject: [PATCH v2 1/2] ARM: dts: vf610-zii: Disable SNVS RTC
Date: Wed, 13 Feb 2019 16:24:38 -0200 [thread overview]
Message-ID: <20190213182439.6184-1-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.
