Subject: [PATCH v1 1/3] dt-bindings: Add cros-ec-ucsi to cros-ec-typec device
 tree documentation

Add documentation for the cros-ec-ucsi device tree definition. Defining
this node will load the cros_ec_ucsi driver which is used for USB-C port
control on PDC based ChromeOS systems. Additionally, update mantainers
list to reflect changes to the ChromeOS USB owners.

 description:
   Chrome OS devices have an Embedded Controller(EC) which has access to
   Type C port state. This node is intended to allow the host to read and
   control the Type C ports. The node for this device should be under a
-  cros-ec node like google,cros-ec-spi.
+  cros-ec node like google,cros-ec-spi. On TCPC systems, ChromeOS should
+  use cros-ec-typec. On PDC systems, ChromeOS should use cros-ec-ucsi.
