Subject: mx25 clocks: Fix MXC_FEC_CLK
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=17c7cf71b44a4fe23a34de1f9d572623d2ed19f7;p=project%2Fbcm63xx%2Fu-boot.git

mx25 clocks: Fix MXC_FEC_CLK

mxc_get_clock(MXC_FEC_CLK) should return the IPG clock, not the AHB clock.

Also, imx_get_fecclk() was correct but reimplemented the calculation of the IPG
clock, so remove the duplicated code.
