Merge branch 'i2c/for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang: "For 3.14, the I2C subsystem has the following to offer: - new drivers for Renesas RIIC and RobotFuzz OSIF - driver cleanups & improvements & bugfixes Pretty standard stuff this time, I'd say. There is more complex stuff coming up, but I didn't have the bandwidth between the years to pull it in for this release.

+* NXP PCA954x I2C bus switch
+
+Required Properties:
+
+ - compatible: Must contain one of the following.
+ "nxp,pca9540", "nxp,pca9542", "nxp,pca9543", "nxp,pca9544",
+ "nxp,pca9545", "nxp,pca9546", "nxp,pca9547", "nxp,pca9548"
+
+ - reg: The I2C address of the device.
+
+ The following required properties are defined externally:
+
+ - Standard I2C mux properties. See i2c-mux.txt in this directory.
+ - I2C child bus nodes. See i2c-mux.txt in this directory.
+
+Optional Properties:
+
+ - reset-gpios: Reference to the GPIO connected to the reset input.
+
+
+Example:
+
+ i2c-switch@74 {
+ compatible = "nxp,pca9548";
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <0x74>;
+
+ i2c@2 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <2>;
+
+ eeprom@54 {
+ compatible = "at,24c08";
+ reg = <0x54>;
+ };
+ };
+
+ i2c@4 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <4>;
+
+ rtc@51 {
+ compatible = "nxp,pcf8563";
+ reg = <0x51>;
+ };
+ };
+ };
