>Subject: [PATCH 3/4] arm: drop eSDHC clock getting in mxc_get_clock() for
>layerscape
>
>Although layerscape platforms reuse mxc_get_clock() of i.MX platforms,
>eSDHC clock getting do not have to use it. It uses global data
>gd->arch.sdhc_clk directly in fsl_esdhc driver. Even there are more
>than one eSDHC controllers on SoC, they use same reference clock.
