From 2581588a55cfbd17088e6fdc7fedd535d0a1a0e4 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Andr=C3=A9=20Draszik?= Date: Tue, 25 Feb 2020 16:11:57 +0000 Subject: [PATCH] ARM: dts: imx7s: add snvs clock to pwrkey MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit On i.MX7, the SNVS requires a clock. This is similar to the clock bound to the SNVS RTC node, but if the SNVS RTC driver isn't enabled, then SNVS doesn't work, and as such the pwrkey driver doesn't work (i.e. hangs the kernel, as the clock isn't enabled). Also see commit 7af05bb4f832 ("ARM: dts: imx7s: add snvs rtc clock") for a similar fix.
