* cleanup: DECLARE_CONSOLE_COMMAND only needs 4 argsBill Richardson2016-08-241-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | Since pretty much always, we've declared console commands to take a "longhelp" argument with detailed explanations of what the command does. But since almost as long, we've never actually used that argument for anything - we just silently throw it away in the macro. There's only one command (usbchargemode) that even thinks it defines that argument. We're never going to use this, let's just get rid of it. BUG=none BRANCH=none CQ-DEPEND=CL:*279060 CQ-DEPEND=CL:*279158 CQ-DEPEND=CL:*279037 TEST=make buildall; tested on Cr50 hardware Everything builds. Since we never used this arg anyway, there had better not be any difference in the result.

* usb_mux: Add support for host-controlled 'virtual' USB muxShawn Nematbakhsh2016-06-241-0/+22
| | | | | | | | | | | | | | | | | | | | | | | | For designs where the host SOC is responsible for setting the USB-C SS mux, the EC must track the desired mux state and inform the host when the desired state changes. Then, the host must ask the EC for the new desired state and set the mux accordingly. BUG=chrome-os-partner:52639 BRANCH=None TEST=Manual on gru with subsequent commit.

* usb_mux: Add a callback for board specific initDuncan Laurie2015-11-241-0/+4
| | | | | | | | | | | | | | | This adds a callback for board specific initialization that is called after the driver init function. This will allow a board to apply port-specific tuning (such as USB EQ settings) to the mux chip.

* usb_mux: Add driver interface for USB-C muxesShawn Nematbakhsh2015-06-301-0/+150
In preparation for adding support for additional USB-C mux chips, add a new high-level USB-C mux interface usb_mux.c. usb_mux functions are now called from pd code instead of board-level functions. usb_mux calls down into a mux chip-specific driver (currently pi3usb30532) or board-specific drivers which toggle GPIOs (for legacy boards). BUG=chrome-os-partner:41696 TEST=Manual on Glados in subsequent commit. Verify set() and get() functions set and return consistent values. Verify that USB SS device functions when muxes are set to dock or USB. Also, verify that DP dongle and USB SS device are functional on both PD ports on samus_pd.
