platform/chrome: cros_ec_typec: Flush pending work

2021-02-11T21:18:46Z

When a PD notifier event arrives, a new work event won't be enqueued if the current one hasn't completed. This could lead to dropped events. So, flush any pending work before scheduling the new instance. Signed-off-by: Prashant Malani Link: https://lore.kernel.org/r/20210211193221.610867-1-pmalani@chromium.org Signed-off-by: Benson Leung

platform/chrome: cros_ec_types: Support disconnect events without partners

2021-02-06T00:43:09Z

There are certain scenarios, where a disconnect event might occur on a Type-C port with no port partners. This is required to enable communication to Burnside Bridge USB4 retimers.

platform/chrome: cros_ec_typec: Skip port partner check in configure_mux()

2021-02-06T00:41:00Z

For certain needs like updating the USB4 retimer firmware when no device are connected, the Type-C ports require mux configuration, to be able to communicate with the retimer. So removed the above check to allow for mux configuration of Type-C ports, to enable retimer communication.

platform/chrome: cros_ec_typec: Decouple partner removal

2021-02-02T23:00:45Z

Currently, we return if there is no partner present when !PD_CTRL_RESP_ENABLED_CONNECTED, without proceeding further. This ties partner removal to cable removal, whereas the two should be independent. Update the check to remove a partner if one was registered, but continue after that instead of returning.

platform/chrome: cros_ec_typec: Set opmode to PD on SOP connected

2021-02-02T07:49:54Z

When SOP Discovery is done, set the opmode to PD if status indicates SOP is connected. SOP connected indicates a PD contract is in place, and is a solid indication we have transitioned to PD power negotiation, either as source or sink.
