    Hi,

    The VDDSHV_SD_IO node is sourced by the AM64x CAP_VDDSHV_MMC1 pin, and is the output of an internal dual-voltage (3.3V/ 1.8V) LDO.  The voltage level of the LDO is set based on the MMCSD0_POWER_CONTROL register.  The MMCSD0_POWER_CONTROL register is managed by the MMC/SD Linux or RTOS drivers.
