Subject: [PATCH v8 07/11] rtc: sun6i: Add Allwinner H616 support
Date: Fri, 23 Jul 2021 16:38:34 +0100	[thread overview]
Message-ID: <20210723153838.6785-8-andre.przywara@arm.com> (raw)
In-Reply-To: <20210723153838.6785-1-andre.przywara@arm.com>

The H616 RTC changes its day storage to the newly introduced linear day
scheme, so pair the new compatible string with this feature flag.
The clock part is missing an external 32768 Hz oscillator input pin,
for future expansion we must thus ignore any provided clock for now.
