usb: typec: tcpm: Skip sink_cap query only when VDM sm is busy

2021-03-18T08:47:47Z

When port partner responds "Not supported" to the DiscIdentity command, VDM state machine can remain in NVDM_STATE_ERR_TMOUT and this causes querying sink cap to be skipped indefinitely. Hence check for vdm_sm_running instead of checking for VDM_STATE_DONE.

usb: typec: tcpm: Invoke power_supply_changed for tcpm-source-psy-

2021-03-17T20:35:11Z

tcpm-source-psy- does not invoke power_supply_changed API when one of the published power supply properties is changed. power_supply_changed needs to be called to notify userspace clients(uevents) and kernel clients.

usb: typec: Remove vdo[3] part of tps6598x_rx_identity_reg struct

2021-03-17T20:30:47Z

Remove the unused "u32 vdo[3]" part in the tps6598x_rx_identity_reg struct. This helps avoid "failed to register partner" errors which happen when tps6598x_read_partner_identity() fails because the amount of data read is 12 bytes smaller than the struct size. Note that vdo[3] is already in usb_pd_identity and hence shouldn't be added to tps6598x_rx_identity_reg as well.

Commit a079973f462a ("usb: typec: tcpm: Remove tcpc_config configuration mechanism") removed the tcpc_config which includes the Sink VDO and it is not yet added back with fwnode. Add it now.
