From f5a336496e0f9aacb451b3b72eb44f78b3fe604c Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Tue, 28 May 2019 22:30:35 +0200 Subject: [PATCH] dt-bindings: rtc: sun6i: Add the R40 RTC compatible 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.
