CTRL_SLEEP_MOCI# is a signal that is defined for all the SoM implementing the Verdin family specification, this signal is supposed to control the power enable in the carrier board when the system is in deep sleep mode. However this is not possible with Texas Instruments AM62 SoC, IOs output buffer is disabled in deep sleep and IOs are in tri-state mode. Given that we cannot properly control this pin, force it to be always high to minimize potential issues.
