It does not add the full support, some USB PHY specific functions not being available currently in the generic PHY subsystem (e.g. usb_phy_set_power()). But it allows to use the generic PHY framework in other cases, and might help others to convert their USB PHY drivers. A little background: I submitted a series to support USB on Berlin SoCs[1]. One patch added a new PHY driver in drivers/usb/phy and Felipe asked it to be in the generic PHY framework instead[2]. This PHY being used by a ChipIdea driver, changes were needed in ChipIdea, OTG and HCD. This is done in 3 steps: 1. moving the OTG state from the USB PHY structure to the OTG one 2. renaming the field 'phy' to 'usb_phy' 3. adding a field for the generic framework PHY and dissociating its use from the USB PHY one Step 1 is in the first patch. Steps 2 and 3 are done in OTG, HCD and CHipIdea subsystems in patches 2 to 4 (one per subsystem). I tested it by using the ChipIdea driver I introduced, both with an USB PHY and a PHY driver successfully. I also compiled a multi_v7 kernel, with every driver I could enable in the USB section. I'd like more people to test and your inputs and suggestions on these changes. Feel free to add Ccs if others might be interested in this. If needed patches can be squashed or divided, I tried there to group modifications by USB framework parts (OTG, HCD, ChipIdea). Patches can also be found at: git://git.free-electrons.com:users/antoine-tenart/linux.git usb-phy Thanks a lot!
