Subject: [PATCH] dt-bindings: convert i2c-cros-ec-tunnel.txt to yaml
Convert the binding file i2c-cros-ec-tunnel.txt to yaml format.
This was tested and verified on ARM and ARM64 with:
make dt_binding_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/i2c/i2c-cros-ec-tunnel.yaml
make dtbs_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/i2c/i2c-cros-ec-tunnel.yaml

-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>;
-
- google,remote-bus = <0>;
-
- battery: sbs-battery@b {
- compatible = "sbs,sbs-battery";
- reg = <0xb>;
- sbs,poll-retry-count = <1>;
- };
- };
- }
