Subject: clk: sunxi-ng: Fix missing CLK_SET_RATE_PARENT in ccu-sun4i-a10.c
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3f745fe61ac6c9e9783ec4c247171ac616d66c8b;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

clk: sunxi-ng: Fix missing CLK_SET_RATE_PARENT in ccu-sun4i-a10.c

commit a894990ac994a53bc5a0cc694eb12f3c064c18c5 upstream.

When using cpufreq-dt with default govenor other than "performance"
system freezes while booting.
Adding CLK_SET_RATE_PARENT | CLK_IS_CRITICAL to clk_cpu fixes the
problem.

Tested on Cubietruck (A20).
