[PATCH] clk: qcom: Fix sdc 144kHz frequency entry

From: Mike Turquette <hidden>
Date: 2014-09-02 21:44:02
Also in: linux-arm-msm

Quoting Stephen Boyd (2014-08-29 12:49:26)
The pre-divider for the sdc clocks only has 2 bits in it, so we
can't possibly divide by anything larger than 4 here.
Furthermore, we program the value of ~(n - m) and the n value is
larger than 8 bits (max of 256). Replace this entry with 200kHz
which is close enough to 144kHz to be usable.

Fixes: 24d8fba44af3 "clk: qcom: Add support for IPQ8064's global clock controller (GCC)"
Signed-off-by: Stephen Boyd <redacted>
Do you need this pulled into a 3.17-rc?

Regards,
Mike
