Hi, These are the remaining four patches of the series, now rebased on top of the latest usb-next. No other changes.
v5 cover letter: I have to use IS_REACHABLE() instead of IS_ENABLED() also in include/linux/usb.h. Otherwise compilation will fail if the Type-C class is build-in while USB is a module. I'm sorry for re-sending these so fast, immediately after v4. Normally I would wait, but I'll be taking a short vacation starting from right now, and I'm still hoping to get these into v5.13. v4 cover letter: One more version. I used #ifdef when I should have used #if IS_DEFINED(). Thanks Guenter for pointing that out. I'm sending this version right away because of the holidays. I'm not changing anything else except that one fix. v3: cover letter: Third version: ifdefs now in the header files as they should be. v2 cover letter: This is the second version of this series. The "Iterator for ports" patch is now moved to the end of the series (5/6). I'm now using usb_for_each_dev() in usb_for_each_port like Alan suggested, and I'm now using usb_port_peer_mutex to lock the ports while we're dealing with them in __each_hub(). The original cover letter: Adding a simple function typec_link_port() that can be used to create a symlink "connector" that points to the USB Type-C connector of a port. It is used with USB ports initially, but hopefully later also with other things like DisplayPorts. Being able to see which connector is connected to a port is important in general, but it is really important when for example the data or power role of a device needs to swapped. The user probable wants to know which USB device is disconnected if role swap on a USB Type-C connector is executed. Hope these are OK. thanks, Heikki Krogerus (4): usb: typec: Port mapping utility usb: Link the ports to the connectors they are attached to usb: Iterator for ports usb: typec: Link all ports during connector registration Documentation/ABI/testing/sysfs-bus-usb | 9 + drivers/usb/core/port.c | 3 + drivers/usb/core/usb.c | 46 ++++ drivers/usb/typec/Makefile | 2 +- drivers/usb/typec/class.c | 12 +- drivers/usb/typec/class.h | 9 + drivers/usb/typec/port-mapper.c | 277 ++++++++++++++++++++++++ include/linux/usb.h | 9 + include/linux/usb/typec.h | 13 ++ 9 files changed, 377 insertions(+), 3 deletions(-) create mode 100644 drivers/usb/typec/port-mapper.c -- 2.30.2
