[PATCH 2/2] usb: chipidea: imx: Fix ULPI on imx53

2018-01-24 Thread Sebastian Reichel
Traditionally, PORTSC should be set before initializing ULPI phys. But setting PORTSC before powering on the phy results in a kernel freeze on imx53 based GE PPD. As a workaround this initializes the phy early in the imx platform code and disables phy power management from the core.
