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 66f5f3f56aed
("ARM: dts: imx7s: add snvs rtc clock")
for a similar fix.
