* servo_v4p1: Add mechanism to enable/disable USB3 to DUTŁukasz Hajec2023-03-091-0/+2
| | | | | | | | | | | | | | | | | | This CL disables USB3 to DUT by default. It overwrites TUSB1064 usb_mux set method to always prevent or allow using USB3 mode in this mux/switch. This CL also adds console command (and needed backed) that can be used to enable/disable USB3 to DUT.

* usb_mux: add TUSB546 driverTing Shen2022-05-101-1/+1
| | | | | | | | | | | | | | | | | | | Reuse the code from existing TUSB1064/TUSB1044 driver and add TUSB546 specific logic to it. Currently the only change is that we will enable IN_HPD when mux enters dock mode, instead of using hpd_update.

* usb_mux: tusb1064: Add method to set DP Rx EQ gainScott Collyer2021-11-231-0/+9
| | | | | | | | | | | | | | | | | | | | | | This CL adds a method to set DP Rx EQ gain. The previous version of the driver was enabling a 10 dB gain by default in the init function. This CL removes setting both gain and EQ_OVERRIDE by default. A separate CL in the stack moves the 10dB gain setting to the board.c file for the only other board that currently is using the TUSB1064. BUG=b:206059703 BRANCH=quiche TEST=Verified on gingerbread that both EQ_OVERRIDE is set and the gain is set in both registers as expected.
