Hello,
This patch set adds UDC support to the isp1760 driver, to be used with the
ISP1761 dual-role USB controller.
The first 21 patches rework the isp1760 driver to prepare it for UDC support.
In particular they removes the direct HCD dependencies from the glue code
(01/26 to 08/26), creates core initialization code shared by the HCD and UDC
(18/26) and move common initialization code to the core (19/26 to 21/26).
Patch 22/26 adds UDC support, patch 23/26 moves the driver to
drivers/usb/isp1760/, and patches 24/26 to 26/26 make HCD support optional.
The ISP1761 has three USB ports, with port 1 configurable in host or peripheral
mode with OTG support, and ports 2 and 3 supporting host mode only. OTG
support is not implemented yet, port 1 can thus be configured in host or
peripheral mode only.
The UDC driver has been successfully tested with the g_zero and g_mass_storage
gadgets.
Felipe, I've tested compilation with all possible options of CONFIG_USB,
CONFIG_USB_STORAGE, CONFIG_USB_ISP1760 and CONFIG_USB_ISP1760_*_ROLE.
Changes compared to v3:
- Fix compilation breakage due to isp1760 leftovers in
drivers/usb/host/Makefile
- Add patches 01/26 to 04/16 that have been dropped from the USB gadget
master branch
- Add patches 25/26 and 26/26
Global changes compared to v2:
- Rebase on top of Felipe's testing/next branch
- Drop patches that have been merged already
- Add patch 19/20 and 20/20
Global changes compared to v1:
- Replace GPIO request move by patch 01/22
- Split PORT1 configuration to separate patch
- Drop the shutdown implementation patch
- Add patches 02/22, 04/22, 05/22, 13/22, 14/22
See individual patches for details.
