Subject: [PATCH 4.9 115/206] clk: sunxi-ng: sun8i-a23: Set CLK_SET_RATE_PARENT for audio module clocks

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

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

From: Chen-Yu Tsai <wens@...e.org>

commit 937ff9ded8b6ebe8963ade55bdd77a61ded88075 upstream.

The audio module clocks are supposed to be set according to the sample
rate of the audio stream. The audio PLL provides the clock signal for
these module clocks, and only it is freely tunable.

Set CLK_SET_RATE_PARENT for the audio module clocks so their users can
properly tune the clock rate.
