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.

Why are you answering questions here in the changelog instead of the
thread where they were originally asked?

Changelog should really only list the things that were change.

Thanks,
