Subject: [PATCH 2/3] ARM: dts: meson8b: ec100: enable the RTC
Date: Sat, 13 Apr 2019 18:34:22 +0200 [thread overview]
Message-ID: <20190413163423.15149-3-martin.blumenstingl@googlemail.com> (raw)
In-Reply-To: <20190413163423.15149-1-martin.blumenstingl@googlemail.com>
The RTC is always enabled on this board since the battery is already
connected in the factory.
According to the schematics the VCC_RTC regulator (which is either
powered by the internal 3.3V or a battery) is connected to the 0.9V
RTC_VDD input of the SoCs.
