      1Broadcom Northstar2 IOMUX Controller
      2
      3The Northstar2 IOMUX controller supports group based mux configuration. There
      4are some individual pins that support modifying the pinconf parameters.
      5
      6Required properties:
      7
      8- compatible:
      9    Must be "brcm,ns2-pinmux"
     10
     11- reg:
     12    Define the base and range of the I/O address space that contains the
     13    Northstar2 IOMUX and pin configuration registers.
     14
     15Properties in sub nodes:
     16
     17- function:
     18    The mux function to select
     19
     20- groups:
     21    The list of groups to select with a given function
     22
     23- pins:
     24    List of pin names to change configuration
     25
     26The generic properties bias-disable, bias-pull-down, bias-pull-up,
     27drive-strength, slew-rate, input-enable, input-disable are supported
     28for some individual pins listed at the end.

     33For example:

     35	pinctrl: pinctrl@6501d130 {
     36		compatible = "brcm,ns2-pinmux";
     37		reg = <0x6501d130 0x08>,
     38		      <0x660a0028 0x04>,
     39		      <0x660009b0 0x40>;
     40
     41		pinctrl-names = "default";
     42		pinctrl-0 = <&nand_sel>, <&uart3_rx>, <&sdio0_d4>;
     43
     44		/* Select nand function */
     45		nand_sel: nand_sel {
     46			function = "nand";
     47			groups = "nand_grp";
     48		};
     49
     50		/* Pull up the uart3 rx pin */
     51		uart3_rx: uart3_rx {
     52			pins = "uart3_sin";
     53			bias-pull-up;
     54		};
     55
     56		/* Set the drive strength of sdio d4 pin */
     57		sdio0_d4: sdio0_d4 {
     58			pins = "sdio0_data4";
     59			drive-strength = <8>;
     60		};
     61	};
