Merge branch 'i2c/for-4.12' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux

Pull i2c updates from Wilfram Sang:
 "I2C has the following updates for you:

   - an immutable cross-subsystem branch fixing PMIC access on Intel
     Baytrail

   - bigger driver updates to the designware, meson, exynos5 drivers

   - new i2c_acpi_new_device() function to create devices from ACPI

   - struct i2c_driver has now a flag 'disable_i2c_core_irq_mapping' to
     allow custom IRQ mapping in case the default does not fit

   - mux subsystem centralized error messages in its core

   - new driver for ltc4306 i2c mux

   - usual set of small updates"

+* Linear Technology / Analog Devices I2C bus switch
+
+Required Properties:
+
+  - compatible: Must contain one of the following.
+    "lltc,ltc4305", "lltc,ltc4306"
+  - 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:
+
+  - enable-gpios: Reference to the GPIO connected to the enable input.
+  - i2c-mux-idle-disconnect: Boolean; if defined, forces mux to disconnect all
+    children in idle state. This is necessary for example, if there are several
+    multiplexers on the bus and the devices behind them use same I2C addresses.
+  - gpio-controller: Marks the device node as a GPIO Controller.
+  - #gpio-cells: Should be two.  The first cell is the pin number and
+	the second cell is used to specify flags.
+	See ../gpio/gpio.txt for more information.
+  - ltc,downstream-accelerators-enable: Enables the rise time accelerators
+	on the downstream port.
+  - ltc,upstream-accelerators-enable: Enables the rise time accelerators
+	on the upstream port.
+
+Example:
+
+	ltc4306: i2c-mux@4a {
+		compatible = "lltc,ltc4306";
+		#address-cells = <1>;
+		#size-cells = <0>;
