Subject[PATCH] clk: sunxi-ng: ccu-sun6i-rtc: set rtc-32k to critical
Date
RTC itself is the one and only consumer of rtc-32k clock. As the rtc
should be always running, set rtc-32k clock to critical, to prevent it
from being gated by the kernel.

Fixes: d91612d7f01a ("clk: sunxi-ng: Add support for the sun6i RTC clocks")
