Subject: [PATCH 2/2] ARM: dts: imx6q-cubox-i: Disable the internal RTC
Date: Tue, 28 Apr 2015 23:59:27 -0300 [thread overview]
Message-ID: <1430276367-18068-2-git-send-email-festevam@gmail.com> (raw)
In-Reply-To: <1430276367-18068-1-git-send-email-festevam@gmail.com>
From: Fabio Estevam <fabio.estevam@freescale.com>
The internal SNVS RTC on imx6q-cubox-i is not battery backed and there
is a PCF8523 that is battery backed on CuBox-i2eX and CuBox-i4Pro models.
Disable the internal RTC in favour of the battery backed one, so that
we can have a valid clock setting right after boot.
