Subject: [PATCH 05/10] dt-bindings: rtc: sun6i: Add the R40 RTC compatible
Date: Mon, 27 May 2019 14:00:37 +0200	[thread overview]
Message-ID: <8be02c659fe4191dbf1d3c8dcb1ded8ff92e2dda.1558958381.git-series.maxime.ripard@bootlin.com> (raw)
In-Reply-To: <290402405a34506997fd2fab2c4c1486dbe6b7e5.1558958381.git-series.maxime.ripard@bootlin.com>

The R40 has a pretty different RTC compared to the other SoCs we've
encountered so far, the most important difference being that it now has
only a single interrupt, compared to the previous SoCs having two.

Let's add a compatible for that.
