Subject: [PATCH] clk: sunxi-ng: sun5i: Add clk_set_rate_parent to the CPU
clock
References: bnc#1060662
Patch-mainline: 4.12.6
Git-commit: 9735ee9e3cc3ba113ac96b0368ef3f1a73092a23
commit 9735ee9e3cc3ba113ac96b0368ef3f1a73092a23 upstream.
The current CPU clock is missing the option to change the rate of its
parents, leading to improper rates calculated by cpufreq, and eventually
crashes.
Fixes: 5e73761786d6 ("clk: sunxi-ng: Add sun5i CCU driver")
