Hi,

Addressed three comments from v8:
1. Fixed the make dt_binding_check that Rob Herring pointed out in
   "dt-bindings: usb: Maxim type-c controller device tree binding
   document"
   https://lkml.org/lkml/2020/9/22/720

2. Moved to string based enums for new-source-frs-typec-current to
   address comments from Rob herring for:
   "dt-bindings: connector: Add property to set initial current cap
   for FRS". As a result, introduced another patch:
   "usb: typec: tcpm: Parse frs type-c current from device tree"
   to refactor tcpm code to read new-source-frs-typec-current from
   device tree. Previously this is was a uint32.
   https://lkml.org/lkml/2020/9/22/729

3. To address Heikki's comment on Auto discharge disconnect threshold
   https://lkml.org/lkml/2020/9/21/1857
   a. Removed the call to tcpm_set_auto_vbus_discharge_threshold
      from source attach path.
   b. Moved logic of setting TCPC_VBUS_SINK_DISCONNECT_THRESH_MAX to
      tcpci.c as the tcpci_maxim was actually setting the default
      values. Removed the get_auto_vbus_discharge_threshold callback
      from tcpci_data for now. Can be added later if needed.

4. Added additional patches to address an isssue where vbus was being
   left post disconnect after Fast Role Swap operation is executed.
   a. usb: typec: tcpm: frs sourcing vbus callback
   b. usb: typec: tcpci: frs sourcing vbus callback
   c. usb: typec: tcpci_max77759: Fix vbus stuck on upon diconnecting sink

Thanks,
Badhri.
