[PATCH 4.12 041/106] clk: sunxi-ng: sun5i: Add clk_set_rate_parent to the CPU clock

[Greg Kroah-Hartman]

4.12-stable review patch.  If anyone has any objections, please let me know.

------------------

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.
