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.
|
||||
|
||||
|
||||
Required properties:
|
||||
- compatible: google,cros-ec-i2c-tunnel
|
||||
- google,remote-bus: The EC bus we'd like to talk to.
|
||||
|
||||
Optional child nodes:
|
||||
- One node per I2C device connected to the tunnelled I2C bus.
|
||||
|
||||
|
||||
Example:
|
||||
cros-ec@0 {
|
||||
compatible = "google,cros-ec-spi";
|
||||
|
||||
...
|
||||
|
||||
i2c-tunnel {
|
||||
compatible = "google,cros-ec-i2c-tunnel";
|
||||
#address-cells = <1>;
|
||||
#size-cells = <0>;
|
||||
|
||||
