Hello,
The purpose of this patch set is to switch from driver xhci-fsl to dwc3-generic for DWC3 IP on Layerscape platforms. Whith this change, now user can enable USB device mode by merely updating property 'dr_mode' accordingly.
I also port some DWC3's errata workaorunds from driver xhci-fsl (by referring to Linux kernel mainline version implemenattion).
Besides that, I fixed a PHY init problem which observed on Lyerscape platforms (such as LS1088ardb).
Regards, Ran
Change in v2: - Remove [2/7] usb: dwc3: add disable receiver detection in P3 quirk, because I found it causes Linux kenrel fail to detect USB device, need further check.
