H A Dsdhci-esdhc.hdiff 19c3a0ef65adf090cb592dfe3e575f40322c88d8 Thu Apr 20 03:14:40 CDT 2017 yangbo lu <yangbo.lu@nxp.com> mmc: sdhci-of-esdhc: add peripheral clock support

eSDHC could select peripheral clock or platform clock as clock source by
the PCS bit of eSDHC Control Register, and this bit couldn't be reset by
software reset for all. In default, the platform clock is used. But we have
to use peripheral clock since it has a higher frequency to support eMMC
HS200 mode and SD UHS-I mode. This patch is to add peripheral clock support
and use it instead of platform clock if it's declared in eSDHC dts node.
