Subject: [PATCH v2 0/9] media: cros-ec-cec: Add support for multiple ports


The Google Dibbi chromebox will have two HDMI ports with CEC enabled via
its EC. Currently, the cros-ec-cec driver and the host command interface
to the EC assume there is only one port. E.g. the commands have no
parameter to indicated which port to operate on.

This series adds support for multiple ports. The driver is modified to
manage an array of ports, each with their own CEC adapter and notifier.
The host command interface is modified to support multiple ports. All
changes to interface are backwards compatible.

Changes in v2:
- Make port_num unsigned in handle_cec_event
- Use NULL-terminated arrays for the conns field of cec_dmi_match
- Use a NULL-terminated conns array for the Dibbi match table entry
