The eSDHC_PRSSTAT[SDSTB] bit indicates whether the internal card clock is stable. This bit is for the host driver to poll clock status when changing the clock frequency. It is recommended to clear eSDHC_SYSCTL[SDCLKEN] to remove glitch on the card clock when the frequency is changing. This patch is to disable SDCLKEN bit before changing frequency and enable it after SDSTB bit is set. Signed-off-by:
