The below patch added eSDHC periperhal clock code initially. 2d9ca2c mmc: fsl_esdhc: Add peripheral clock support The purpose was to fix up device tree properties "peripheral-frequency" so that linux could get the periperhal clock by it. However the implementation on both u-boot and linux was only for a Freescale SDK release. The linux part implementation had never been upstreamed. These code should not have been exist on u-boot mainline. Let's remove the powerpc part changes but keep the changes in fsl_esdhc driver. The changes in fsl_esdhc driver could be utilized to support SD UHS and eMMC HS200/HS400 speed modes for current Layerscape ARM platforms. Signed-off-by: Yangbo Lu <yangbo.lu@nxp.com>
