Subject: mx51evk: Use GPIO API for configuring the IOMUX
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=d736ebea1cc335e89643656c3db33f5df55ffb16;p=project%2Fbcm63xx%2Fu-boot.git

mx51evk: Use GPIO API for configuring the IOMUX

GPIO API provides mxc_request_iomux function for setting the IOMUX mode.

Use this function instead of directly writing to the IOMUX register.
