-* Freescale i.MX7 Dual IOMUX Controller
-
-iMX7D supports two iomuxc controllers, fsl,imx7d-iomuxc controller is similar
-as previous iMX SoC generation and fsl,imx7d-iomuxc-lpsr which provides low
-power state retention capabilities on gpios that are part of iomuxc-lpsr
-(GPIO1_IO7..GPIO1_IO0). While iomuxc-lpsr provides its own set of registers for
-mux and pad control settings, it shares the input select register from main
-iomuxc controller for daisy chain settings, the fsl,input-sel property extends
-fsl,imx-pinctrl driver to support iomuxc-lpsr controller.
-
-iomuxc_lpsr: iomuxc-lpsr@302c0000 {
-	compatible = "fsl,imx7d-iomuxc-lpsr";
-	reg = <0x302c0000 0x10000>;
-	fsl,input-sel = <&iomuxc>;
-};
-
-iomuxc: iomuxc@30330000 {
-	compatible = "fsl,imx7d-iomuxc";
-	reg = <0x30330000 0x10000>;
-};
-
-Peripherals using pads from iomuxc-lpsr support low state retention power
-state, under LPSR mode GPIO's state of pads are retain.
-
-Please refer to fsl,imx-pinctrl.txt in this directory for common binding part
-and usage.
-
-Required properties:
-- compatible: "fsl,imx7d-iomuxc" for main IOMUXC controller, or
-  "fsl,imx7d-iomuxc-lpsr" for Low Power State Retention IOMUXC controller.
-- fsl,pins: each entry consists of 6 integers and represents the mux and config
-  setting for one pin.  The first 5 integers <mux_reg conf_reg input_reg mux_val
-  input_val> are specified using a PIN_FUNC_ID macro, which can be found in
-  imx7d-pinfunc.h under device tree source folder.  The last integer CONFIG is
-  the pad setting value like pull-up on this pin.  Please refer to i.MX7 Dual
-  Reference Manual for detailed CONFIG settings.
-- fsl,input-sel: required property for iomuxc-lpsr controller, this property is
-  a phandle for main iomuxc controller which shares the input select register for
-  daisy chain settings.

-Examples:
-While iomuxc-lpsr is intended to be used by dedicated peripherals to take
-advantages of LPSR power mode, is also possible that an IP to use pads from
-any of the iomux controllers. For example the I2C1 IP can use SCL pad from
-iomuxc-lpsr controller and SDA pad from iomuxc controller as:
-
-i2c1: i2c@30a20000 {
-	pinctrl-names = "default";
-	pinctrl-0 = <&pinctrl_i2c1_1>, <&pinctrl_i2c1_2>;
-};
-
-iomuxc-lpsr@302c0000 {
-	compatible = "fsl,imx7d-iomuxc-lpsr";
-	reg = <0x302c0000 0x10000>;
-	fsl,input-sel = <&iomuxc>;
-
-	pinctrl_i2c1_1: i2c1grp-1 {
-		fsl,pins = <
-			MX7D_PAD_GPIO1_IO04__I2C1_SCL 0x4000007f
-		>;
-	};
-};
-
-iomuxc@30330000 {
-	compatible = "fsl,imx7d-iomuxc";
-	reg = <0x30330000 0x10000>;
-
