Subject: [PATCH 0/3] platform/chrome: Add Type C connector class driver

The following series introduces a Type C port driver for Chrome OS devices
that have an EC (Embedded Controller). It derives port information from
ACPI or DT entries. This patch series adds basic support, including
registering ports, and setting certain basic attributes.

I thought I’d send it out as an RFC to get some comments on whether the
general approach is right. Subsequent iterations of the series will
include adding port partner information as well as integration with mux
agents. This might tie in with Heikki’s work here:

https://github.com/krohei/linux/commit/976378fbfe4a29b892d39ade07efce042640ff4c

Based on feedback, I can incorporate comments or adopt another approach altogether.
