3 iMX7D supports two iomuxc controllers, fsl,imx7d-iomuxc controller is similar
4 as previous iMX SoC generation and fsl,imx7d-iomuxc-lpsr which provides low
5 power state retention capabilities on gpios that are part of iomuxc-lpsr
6 (GPIO1_IO7..GPIO1_IO0). While iomuxc-lpsr provides its own set of registers for
8 iomuxc controller for daisy chain settings, the fsl,input-sel property extends
9 fsl,imx-pinctrl driver to support iomuxc-lpsr controller.
11 iomuxc_lpsr: iomuxc-lpsr@302c0000 {
12 	compatible = "fsl,imx7d-iomuxc-lpsr";
14 	fsl,input-sel = <&iomuxc>;
17 iomuxc: iomuxc@30330000 {
18 	compatible = "fsl,imx7d-iomuxc";
22 Peripherals using pads from iomuxc-lpsr support low state retention power
29 - compatible: "fsl,imx7d-iomuxc" for main IOMUXC controller, or
30   "fsl,imx7d-iomuxc-lpsr" for Low Power State Retention IOMUXC controller.
37 - fsl,input-sel: required property for iomuxc-lpsr controller, this property is
38   a phandle for main iomuxc controller which shares the input select register for
56 While iomuxc-lpsr is intended to be used by dedicated peripherals to take
59 iomuxc-lpsr controller and SDA pad from iomuxc controller as:
66 iomuxc-lpsr@302c0000 {
67 	compatible = "fsl,imx7d-iomuxc-lpsr";
69 	fsl,input-sel = <&iomuxc>;
78 iomuxc@30330000 {
79 	compatible = "fsl,imx7d-iomuxc";
