From: Gwendal Grignou <gwendal@chromium.org>
Chromebooks can have more than one Embedded Controller with different functinality. For example there may be a EC that handles Power Delivery (PD) or another one that is a Sensor Hub (SH). So there should be a way to specify the function so that is reflected in the character device name and the sysfs entries.
Add a "google,cros-ec-name" DT property to the ChromeOS EC binding document to change the EC name based on its function.
