It seems that if L3_INIT clkdomain is kept in HW_AUTO while usb_otg_ss is in use then there are random chances that the usb_otg_ss module will fail to completely idle. i.e. IDLEST = 0x2 instead of 0x3.
Preventing L3_INIT from HW_AUTO while usb_otg_ss module is in use fixes this issue.
We don't know yet if usb_otg_ss instances 3 and 4 are affected by this issue or not so don't add this flag for those instances.

I've dropped the patch that caused this problem now, will push out a -rc2 in a few minutes, thanks.
