NXP fsl_esdhc controller supports two reference clocks: platform clock and peripheral clock Peripheral clock can provide higher clock frequency which is required to be used for tuning of SD UHS mode and eMMC HS200/HS400 modes. Peripheral clock is enabled by default by defining config option FSL_ESDHC_USE_PERIPHERAL_CLK if eMMC HS200/HS400 modes are supported.
