ENGR00218771 mx6 USB:USB disconnect issue verification on MX6QTO1.2/MX6DLTO1.1
- for Rigel1.1/Arik1.2, bit 17 of HW_USBPHY_IP will be set, it will fix the
issue that no wakeup between SUSP/PHCD. And the usb_platform_rh_suspend/
usb_platform_rh_resume do not need do complex software workaround, only
need set/clear the workaround bit.
- for Megrez , bit 17 and bit 18 of HW_USBPHY_IP will be set, it will fix the
issue that no wakeup between SUSP/PHCD and disconnect after resume. No need
do any software workaround.
