[PATCH 0/3] usb: typec: tcpm: sink (ufp) accessory mode support

[Michael Grzeschik]

This series is adding support to reach the DEBUG_ACC_ATTACHED state
when configured as sink. It also extends the tcpm_acc_attach function
to handle sink and src cases and sets the proper modal state when
calling tcpm_set_role.

[PATCH 1/3] usb: typec: tcpm: allow to use sink in accessory mode

[Michael Grzeschik]

Since the function tcpm_acc_attach is not setting the data and role for
for the sink case we extend it to check for it first.

[PATCH 2/3] usb: typec: tcpm: allow sink (ufp) to toggle into accessory mode debug

[Michael Grzeschik]

This patch extends the is_debug macro to cover the sink case (ufp). It
also handles the transition to access the DEBUG_ACC_ATTACHED state in
the sink case. It also handles the debounce case in which the cc
pins are not immediately valid after the plug event.

[PATCH 3/3] usb: typec: tcpm: allow switching to mode accessory to mux properly

[Michael Grzeschik]

The funciton tcpm_acc_attach is not setting the proper state when
calling tcpm_set_role. The function tcpm_set_role is currently only
handling TYPEC_STATE_USB. For the tcpm_acc_attach to switch into other
modal states tcpm_set_role needs to be extended by an extra state
parameter. This patch is handling the proper state change when calling
tcpm_acc_attach.
