Subject: [PATCH 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.


Reka Norman (9):
  media: cros-ec-cec: Use cros_ec_cmd to send host commands
  media: cros-ec-cec: Manage an array of ports
  media: cros-ec-cec: Support multiple ports in set/get host commands
  media: cros-ec-cec: Support multiple ports in write command
  media: cros-ec-cec: Support multiple ports in MKBP cec_events
  media: cros-ec-cec: Support receiving messages from multiple ports
  media: cros-ec-cec: Allow specifying multiple HDMI connectors
  media: cros-ec-cec: Get number of CEC ports from EC
  media: cros-ec-cec: Add Dibbi to the match table
