Subject: clk: sunxi-ng: sun5i: Add clk_set_rate_parent to the CPU clock
From: Maxime Ripard <maxime.ripard@xxxxxxxxxxxxxxxxxx>
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.
