I want to initialize USB HSIC port on our i.MX7D custom board. I managed to enable the LDO_1P2 power by setting bit 0 of the Anadig 1.2V HSIC Regulator Control Register.
However, I cannot find a way to enable the SW_HSIC_1P0 power switch for the USB HSOC 1.0V power supply as stated in 126.96.36.199.4 of the reference manual.
Which registers will I have to control to enable that power switch?
Trying to set the PP bit in the Port Status and Control register to enable port power causes u-boot to hang.
