Besides each board use a different chip for the hub, on both they're controlled the same way. Such boards come with an integrated 4-port USB hub on it, set on what it seems to be a non-standard way: on both implementations, the USB type-C port is used to detect the USB role. When in host mode, the 3.3V power supply (VDD33 pins) for the hub are disabled. That disables the USB I/O on type-A ports. When USB type-C is on device mode, the OTG is switched via a GPIO pin to device mode, and the hub is powered on. A Type-C power supply line is also controlled depending on the role. - The entire series which contains the remaining patches to support PCI and USB on HiKey970, and USB on HiKey960 is at: https://github.com/mchehab/linux/commits/linux-master The patches needed by the USB on HiKey970 were already merged upstream. So, the above branch applies on the top of Linux master branch. Tested on HiKey 960: $ lsusb Bus 002 Device 002: ID 0424:5734 Standard Microsystems Corp.

TUSB8041 4-Port Hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub v4: - Improved description at the DT schema; - Use just one compatible, as there's no difference between HiKey 960 and 970 with regards to how the hub should be controlled; - parse usb-role-switch property at the driver; - make the properties that depends on usb-role-switch optional. v3: - The examples at the dt-bindings were updated to reflect the actual DTS content and won't produce any warnings; - Added John Stultz SoB to Hikey960 DTS patch; - Added a patch for the mux hub driver for it to work with the newer schema; John Stultz (1): arm64: dts: hisilicon: Add usb mux hub for hikey960 Mauro Carvalho Chehab (2): misc: hisi_hikey_usb: change the DT schema arm64: dts: hisilicon: Add usb mux hub for hikey970 Yu Chen (1): dt-bindings: misc: add schema for USB hub on Kirin devices .../bindings/misc/hisilicon,hikey-usb.yaml | 87 +++++++++++++ .../boot/dts/hisilicon/hi3660-hikey960.dts | 35 +++++- .../boot/dts/hisilicon/hi3670-hikey970.dts | 23 ++++ drivers/misc/hisi_hikey_usb.c | 119 +++++++++--------- 4 files changed, 206 insertions(+), 58 deletions(-) create mode 100644 Documentation/devicetree/bindings/misc/hisilicon,hikey-usb.yaml
