>Subject: [PATCH 1/4] mmc: fsl_esdhc: get clock directly from global data
>
>This patch is to get clock directly from global data.
>
>- Remove uclass clk api method. This was what i.MX platforms were
> using, while QorIQ platforms weren't.
>- Get clock only from global data, dropping mxc_get_clock().
> QorIQ eSDHC controllers on one silicon use same reference clock.
