pinctrl: imx27: imx27 pincontrol driver 



imx27 pincontrol driver using the imx1 core driver. The DT bindings are
similar to other imx pincontrol drivers.

* Freescale IMX27 IOMUX Controller



Required properties:

- compatible: "fsl,imx27-iomuxc"



The iomuxc driver node should define subnodes containing of pinctrl configuration subnodes.



Required properties for pin configuration node:

- fsl,pins: three integers array, represents a group of pins mux and config

  setting. The format is fsl,pins = <PIN MUX_ID CONFIG>.



  PIN is an integer between 0 and 0xbf. imx27 has 6 ports with 32 configurable

  configurable pins each. PIN is PORT * 32 + PORT_PIN, PORT_PIN is the pin

  number on the specific port (between 0 and 31).



  MUX_ID is

    function + (direction << 2) + (gpio_oconf << 4) + (gpio_iconfa << 8) + (gpio_iconfb << 10)



      function value is used to select the pin function.

      Possible values:

          0 - Primary function

          1 - Alternate function

          2 - GPIO

      Registers: GIUS (GPIO In Use), GPR (General Purpose Register)



      direction defines the data direction of the pin.

      Possible values:

          0 - Input

          1 - Output

      Register: DDIR



      gpio_oconf configures the gpio submodule output signal. This does not

      have any effect unless GPIO function is selected. A/B/C_IN are output

      signals of function blocks A,B and C. Specific function blocks are

      described in the reference manual.

      Possible values:

          0 - A_IN

          1 - B_IN

          2 - C_IN

          3 - Data Register

      Registers: OCR1, OCR2



      gpio_iconfa/b configures the gpio submodule input to functionblocks A and

      B. GPIO function should be selected if this is configured.

      Possible values:

          0 - GPIO_IN

          1 - Interrupt Status Register

          2 - Pulldown

          3 - Pullup

      Registers ICONFA1, ICONFA2, ICONFB1 and ICONFB2



  CONFIG can be 0 or 1, meaning Pullup disable/enable.







Example:



iomuxc: iomuxc@10015000 {

	compatible = "fsl,imx27-iomuxc";

	reg = <0x10015000 0x600>;



	uart {

		pinctrl_uart1: uart-1 {

			fsl,pins = <

				0x8c 0x004 0x0 /* UART1_TXD__UART1_TXD */

				0x8d 0x000 0x0 /* UART1_RXD__UART1_RXD */

				0x8e 0x004 0x0 /* UART1_CTS__UART1_CTS */

				0x8f 0x000 0x0 /* UART1_RTS__UART1_RTS */

			>;

		};



		...

	};

};





For convenience there are macros defined in imx27-pinfunc.h which provide PIN

and MUX_ID. They are structured as MX27_PAD_<Pad name>__<Signal name>. The names

are defined in the i.MX27 reference manual.



The above example using macros:



iomuxc: iomuxc@10015000 {

	compatible = "fsl,imx27-iomuxc";

	reg = <0x10015000 0x600>;



	uart {

		pinctrl_uart1: uart-1 {

			fsl,pins = <

				MX27_PAD_UART1_TXD__UART1_TXD 0x0

				MX27_PAD_UART1_RXD__UART1_RXD 0x0

				MX27_PAD_UART1_CTS__UART1_CTS 0x0

				MX27_PAD_UART1_RTS__UART1_RTS 0x0

			>;

		};



		...

	};

};
