There is a case where the user reaches the maximum number of CS in-flight. In that case, the driver rejects the new CS of the user with EAGAIN.

2020-09-22habanalabs: replace armcp with the generic cpucpOded Gabbay13-313/+331
ArmCP mandates that the device CPU is always an ARM processor, which might be wrong in the future. Most of this change is an internal renaming of variables, functions and defines but there are two entries in sysfs which have armcp in their names. Add identical cpucp entries but don't remove yet the armcp entries. Those will be deprecated next year. Add the documentation about it in sysfs documentation.

2020-09-10misc: hisi_hikey_usb: Driver to support onboard USB gpio hub on Hikey960Yu Chen3-0/+215
The HiKey960 has a fairly complex USB configuration due to it needing to support a USB-C port for host/device mode and multiple USB-A ports in host mode, all using a single USB controller. See schematics here: https://github.com/96boards/documentation/raw/master/consumer/hikey/hikey960/hardware-docs/HiKey960_Schematics.pdf This driver acts as a usb-role-switch intermediary, intercepting the role switch notifications from the tcpm code, and passing them on to the dwc3 core. In doing so, it also controls the onboard hub and power gpios in order to properly route the data lines between the USB-C port and the onboard hub to the USB-A ports.
