-Required properties:
-- compatible: i2c-mux-pinctrl
-- i2c-parent: The phandle of the I2C bus that this multiplexer's master-side
-  port is connected to.
-
-Also required are:
-
-* Standard pinctrl properties that specify the pin mux state for each child
-  bus. See ../pinctrl/pinctrl-bindings.txt.
-
-* Standard I2C mux properties. See i2c-mux.yaml in this directory.
-
-* I2C child bus nodes. See i2c-mux.yaml in this directory.
-
-For each named state defined in the pinctrl-names property, an I2C child bus
-will be created. I2C child bus numbers are assigned based on the index into
-the pinctrl-names property.
-
-The only exception is that no bus will be created for a state named "idle". If
-such a state is defined, it must be the last entry in pinctrl-names. For
-example:
-
-	pinctrl-names = "ddc", "pta", "idle"  ->  ddc = bus 0, pta = bus 1
-	pinctrl-names = "ddc", "idle", "pta"  ->  Invalid ("idle" not last)
-	pinctrl-names = "idle", "ddc", "pta"  ->  Invalid ("idle" not last)
-
-Whenever an access is made to a device on a child bus, the relevant pinctrl
-state will be programmed into hardware.
-
-If an idle state is defined, whenever an access is not being made to a device
-on a child bus, the idle pinctrl state will be programmed into hardware.
-
-If an idle state is not defined, the most recently used pinctrl state will be
-left programmed into hardware whenever no access is being made of a device on
-a child bus.
-
-Example:
-
-	i2cmux {
-		compatible = "i2c-mux-pinctrl";
-		#address-cells = <1>;
-		#size-cells = <0>;
-
-		i2c-parent = <&i2c1>;

-NVIDIA Tegra20/Tegra30/Tegra114 I2C controller driver.
-
-Required properties:
-- compatible : For Tegra20, must be one of "nvidia,tegra20-i2c-dvc" or
-  "nvidia,tegra20-i2c".  For Tegra30, must be "nvidia,tegra30-i2c".
-  For Tegra114, must be "nvidia,tegra114-i2c".  Otherwise, must be
-  "nvidia,<chip>-i2c", plus at least one of the above, where <chip> is
-  tegra124, tegra132, or tegra210.
-  Details of compatible are as follows:
-  nvidia,tegra20-i2c-dvc: Tegra20 has specific I2C controller called as DVC I2C
-	controller. This only support master mode of I2C communication. Register
-	interface/offset and interrupts handling are different than generic I2C
-	controller. Driver of DVC I2C controller is only compatible with
-	"nvidia,tegra20-i2c-dvc".
-  nvidia,tegra20-i2c: Tegra20 has 4 generic I2C controller. This can support
-	master and slave mode of I2C communication. The i2c-tegra driver only
-	support master mode of I2C communication. Driver of I2C controller is
-	only compatible with "nvidia,tegra20-i2c".
-  nvidia,tegra30-i2c: Tegra30 has 5 generic I2C controller. This controller is
-	very much similar to Tegra20 I2C controller with additional feature:
-	Continue Transfer Support. This feature helps to implement M_NO_START
-	as per I2C core API transfer flags. Driver of I2C controller is
-	compatible with "nvidia,tegra30-i2c" to enable the continue transfer
-	support. This is also compatible with "nvidia,tegra20-i2c" without
-	continue transfer support.
-  nvidia,tegra114-i2c: Tegra114 has 5 generic I2C controller. This controller is
-	very much similar to Tegra30 I2C controller with some hardware
-	modification:
-	 - Tegra30/Tegra20 I2C controller has 2 clock source called div-clk and
-	   fast-clk. Tegra114 has only one clock source called as div-clk and
-	   hence clock mechanism is changed in I2C controller.
-	 - Tegra30/Tegra20 I2C controller has enabled per packet transfer by
-	   default and there is no way to disable it. Tegra114 has this
-	   interrupt disable by default and SW need to enable explicitly.
-	Due to above changes, Tegra114 I2C driver makes incompatible with
-	previous hardware driver. Hence, tegra114 I2C controller is compatible
-	with "nvidia,tegra114-i2c".
-  nvidia,tegra210-i2c-vi: Tegra210 has one I2C controller that is on host1x bus
-	and is part of VE power domain and typically used for camera use-cases.
-	This VI I2C controller is mostly compatible with the programming model
-	of the regular I2C controllers with a few exceptions. The I2C registers
-	start at an offset of 0xc00 (instead of 0), registers are 16 bytes
-	apart (rather than 4) and the controller does not support slave mode.
-- reg: Should contain I2C controller registers physical address and length.
-- interrupts: Should contain I2C controller interrupts.
-- address-cells: Address cells for I2C device address.
-- size-cells: Size of the I2C device address.
-- clocks: Must contain an entry for each entry in clock-names.
-  See ../clocks/clock-bindings.txt for details.
-- clock-names: Must include the following entries:
-  Tegra20/Tegra30:
-  - div-clk
-  - fast-clk
-  Tegra114:
-  - div-clk
-  Tegra210:
-  - div-clk
-  - slow (only for nvidia,tegra210-i2c-vi compatible node)
-- resets: Must contain an entry for each entry in reset-names.
-  See ../reset/reset.txt for details.
-- reset-names: Must include the following entries:
-  - i2c
-- power-domains: Only for nvidia,tegra210-i2c-vi compatible node and must
-  include venc powergate node as vi i2c is part of VE power domain.
-  tegra210-i2c-vi:
-  - pd_venc
-- dmas: Must contain an entry for each entry in clock-names.
-  See ../dma/dma.txt for details.
-- dma-names: Must include the following entries:
-  - rx
-  - tx

-Example:
-

+          Tegra210 has one I2C controller that is on host1x bus and is part of
+          the VE power domain and typically used for camera use-cases. This VI
+          I2C controller is mostly compatible with the programming model of
+          the regular I2C controllers with a few exceptions. The I2C registers
+          start at an offset of 0xc00 (instead of 0), registers are 16 bytes
+          apart (rather than 4) and the controller does not support slave
+          mode.

+          support for 64 KiB transactions whereas earlier chips supported no
+          more than 4 KiB per transactions.
