[PATCH v2] clk: rockchip: Allow sclk_i2s0 and i2s0_frac to change their parents rate on rk3188

From: Alexander Kochetkov
Date: Fri Jan 29 2016 - 02:58:14 EST


Allow sclk_i2s0 and i2s0_frac to change their parents rate as
that the upstream dividers are purely there to feed sclk_i2s0

Tested on radxarock-lite.

Signed-off-by: Alexander Kochetkov <al.kochet@xxxxxxxxx>

Changes in v2:
Rebased on top of 4.5-rc1 of branch[1]
