title: I2C bus that tunnels through the ChromeOS EC (cros-ec)

On some ChromeOS board designs we've got a connection to the EC
|
|
(embedded controller) but no direct connection to some devices on the
|
|
other side of the EC (like a battery and PMIC). To get access to
|
|
those devices we need to tunnel our i2c commands through the EC.
|
|
|
|
The node for this device should be under a cros-ec node like
|
|
google,cros-ec-spi or google,cros-ec-i2c.
