1 I2C bus that tunnels through the ChromeOS EC (cros-ec)
2 ======================================================
3 On some ChromeOS board designs we've got a connection to the EC (embedded
4 controller) but no direct connection to some devices on the other side of
5 the EC (like a battery and PMIC). To get access to those devices we need
6 to tunnel our i2c commands through the EC.
8 The node for this device should be under a cros-ec node like google,cros-ec-spi
13 - compatible: google,cros-ec-i2c-tunnel
14 - google,remote-bus: The EC bus we'd like to talk to.
17 - One node per I2C device connected to the tunnelled I2C bus.
