Hi, The Intel PMC (Power Management Controller) microcontroller, which is available on most SOCs from Intel, has a function called mux-agent. The mux-agent, when visible to the operating system, makes it possible to control the various USB muxes on the system. In practice the mux-agent is a device that controls multiple muxes. Unfortunately both the USB Type-C Class and the USB Role Class don't have proper support for that kind of devices that handle multiple muxes, which is why I had to tweak the APIs a bit. On top of the API changes, and the driver of course, I'm adding a header for the Thunderbolt 3 alt mode since the "mux-agent" supports it. thanks, Heikki Krogerus (9): usb: typec: mux: Allow the muxes to be named usb: typec: mux: Add helpers for setting the mux state usb: typec: mux: Allow the mux handles to be requested with fwnode usb: roles: Leave the private driver data pointer to the drivers usb: roles: Provide the switch drivers handle to the switch in the API usb: roles: Allow the role switches to be named device property: Export fwnode_get_name() usb: typec: Add definitions for Thunderbolt 3 Alternate Mode usb: typec: driver for Intel PMC mux control drivers/base/property.c | 1 + drivers/usb/cdns3/core.c | 10 +- drivers/usb/chipidea/core.c | 10 +- drivers/usb/dwc3/dwc3-meson-g12a.c | 10 +- drivers/usb/gadget/udc/renesas_usb3.c | 26 +- drivers/usb/gadget/udc/tegra-xudc.c | 8 +- drivers/usb/mtu3/mtu3_dr.c | 9 +- drivers/usb/musb/mediatek.c | 9 +- drivers/usb/roles/class.c | 29 +- .../usb/roles/intel-xhci-usb-role-switch.c | 26 +- drivers/usb/typec/class.c | 10 +- drivers/usb/typec/mux.c | 47 +- drivers/usb/typec/mux/Kconfig | 9 + drivers/usb/typec/mux/Makefile | 1 + drivers/usb/typec/mux/intel_pmc_mux.c | 434 ++++++++++++++++++ include/linux/usb/role.h | 23 +- include/linux/usb/typec_mux.h | 25 +- include/linux/usb/typec_tbt.h | 53 +++ 18 files changed, 667 insertions(+), 73 deletions(-) create mode 100644 drivers/usb/typec/mux/intel_pmc_mux.c create mode 100644 include/linux/usb/typec_tbt.h -- 2.25.0
