Hi Felipe, Ajay, Kishon
In order to add generic USB PHY layer, from my point, below
steps are needed to be done
1. Move generic PHY things from otg/ to phy/
- Split include/linux/usb/otg.h to include/linux/usb/phy.h
and include/linux/usb/otg.h
- Split drivers/usb/otg/otg.c to drivers/usb/otg/otg.c
and drivers/usb/phy/phy.c
- Change CONFIG_USB_OTG_UTILS to CONFIG_USB_PHY_UTILS
- obj-$(CONFIG_USB_OTG) += otg.o
- obj-$(CONFIG_USB_PHY) += phy/
2. Eliminate the relationship between struct usb_otg and struct usb_phy
3. Add generic USB PHY layer support to drivers/usb/phy/phy.c
- generic USB PHY layer is implemented at phy.c
- Related driver's change for adopting this PHY layer
The step 2 is optional, and will take much time.
Any comments are welcome, I will begin step 1 from next week.
Best regards,
Peter Chen
