* chocodile_vpdmcu: Firmware for chocodile mcuSam Hurst2019-04-081-0/+2
| | | | | | | | | | | | | | | | | | Implement Chocodile Charge-Through Vconn Powered firmware for mcu using new Type-C/PD State machine stack. BUG=b:115626873 BRANCH=none TEST=manual Charge-Through was tested on an Atlas running a DRP USB-C/PD state machine with CTUnattached.SNK and CTAttached.SNK states.

* cleanup: fix all the header guardsBill Richardson2015-06-181-3/+3
| | | | | | | | | | | | | | | This unifies all the EC header files to use __CROS_EC_FILENAME_H as the include guard. Well, except for test/ util/ and extra/ which use __TEST_ __UTIL_ and __EXTRA_ prefixes respectively.

* pd: check for collisions before transmittingAlec Berg2014-12-171-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Added check for collision just before transmitting on CC line. To check for collision, RX monitoring is left on all the time (except when in the act of receiving or transmitting, or in between receiving and sending a goodCRC), and a simple check for RX transmission started is used to see if the CC line is idle or not. RX monitoring is also changed to only trigger on 3 edges within 20us, as per the PD spec. When a collision is detected by seeing that CC is not idle, the transmitting packet is dropped. BUG=chrome-os-partner:30135 BRANCH=samus TEST=load onto samus and zinger. make sure we negotiate and make sure custom VDMs succeed. enabled pings and made sure we stay alive with pings for a few min. Also added code to pd_rx_handler to toggle a test point on EVT board to verify the timing of when we get RX interrupts: Change-Id: I22d172163319437d3d901e019eda79d4d592f6b8 Signed-off-by: Alec Berg <alecaberg@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/226118 Reviewed-by: Vincent Palatin <vpalatin@chromium.org>
* Add back unit test for usb_pd"Vic Yang2014-10-041-0/+31
| | | | | | | | | | | | | | | | | | This is mostly the same as previous commits, but with increased delay. Previously, we have short delays (e.g. 3ms) which is too short and may cause instability. Now that we have slowed down the time when running unit tests and increased the delay, this shouldn't cause problems anymore. BUG=chrome-os-partner:31200 TEST=Repeatedly run multiple unit tests in parallel.
