-Broadcom Northstar2 IOMUX Controller
-
-The Northstar2 IOMUX controller supports group based mux configuration. There
-are some individual pins that support modifying the pinconf parameters.
-
-Required properties:
-
-- compatible:
- Must be "brcm,ns2-pinmux"
-
-- reg:
- Define the base and range of the I/O address space that contains the
- Northstar2 IOMUX and pin configuration registers.
-
-Properties in sub nodes:
-
-- function:
- The mux function to select
-
-- groups:
- The list of groups to select with a given function
-
-- pins:
- List of pin names to change configuration
-
-The generic properties bias-disable, bias-pull-down, bias-pull-up,
-drive-strength, slew-rate, input-enable, input-disable are supported
-for some individual pins listed at the end.
-
-For more details, refer to
-Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt
-
-For example:
-
- pinctrl: pinctrl@...1d130 {
- compatible = "brcm,ns2-pinmux";
- reg = <0x6501d130 0x08>,
- <0x660a0028 0x04>,
- <0x660009b0 0x40>;
-
- pinctrl-names = "default";
- pinctrl-0 = <&nand_sel>, <&uart3_rx>, <&sdio0_d4>;
-
- /* Select nand function */
- nand_sel: nand_sel {
- function = "nand";
- groups = "nand_grp";
- };
-
- /* Pull up the uart3 rx pin */
- uart3_rx: uart3_rx {
- pins = "uart3_sin";
- bias-pull-up;
- };
-
- /* Set the drive strength of sdio d4 pin */
- sdio0_d4: sdio0_d4 {
- pins = "sdio0_data4";
- drive-strength = <8>;
- };
- };
