Subject: clk: cdce925: Fix limit check
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5785271ef2bb9ca37ba1b40ec56b8d127caf3b2c;p=openwrt%2Fstaging%2Fblogic.git

clk: cdce925: Fix limit check

It is likely that instead of '1>64', 'q>64' was expected.

Moreover, according to datasheet,
   http://www.ti.com/lit/ds/symlink/cdce925.pdf
   SCAS847I - JULY 2007 - REVISED OCTOBER 2016
PLL settings limits are: 16 <= q <= 63
So change the upper limit check from 64 to 63.
