[PATCH v7 0/2] usb: typec: ucsi: Add ITE IT8851/IT8853 support

[Amber Kao]

This series adds Device Tree bindings and minimal UCSI driver support 
for the ITE IT8851/IT8853 USB Type-C Power Delivery controller over I2C.

Changes in v7:
- dt-bindings: define 'reg' for the connector@[01] nodes, since a
  unit-address requires a 'reg' property.
- dt-bindings: dropped Krzysztof's Reviewed-by tag due to the above
  change.
- ucsi_itepd: use guard(mutex) in itepd_process_event(),
  ucsi_itepd_read_cci() and ucsi_itepd_read_message_in().
- ucsi_itepd: kept request_threaded_irq() instead of
  devm_request_threaded_irq(). ucsi_destroy() is not devres-managed and
  runs inside remove(), while a devm IRQ is only released after remove()
  has returned; an interrupt in that window would call
  ucsi_notify_common() on an already destroyed ucsi instance.
