| Synopsys GPIO via CREG (Control REGisters) driver |
| |
| Required properties: |
| - compatible : "snps,creg-gpio-hsdk" or "snps,creg-gpio-axs10x". |
| - reg : Exactly one register range with length 0x4. |
| - #gpio-cells : Since the generic GPIO binding is used, the |
| amount of cells must be specified as 2. The first cell is the |
| pin number, the second cell is used to specify optional parameters: |
| See "gpio-specifier" in .../devicetree/bindings/gpio/gpio.txt. |
| - gpio-controller : Marks the device node as a GPIO controller. |
| - ngpios: Number of GPIO pins. |
| |
| Example: |
| |
| gpio: gpio@f00014b0 { |
| compatible = "snps,creg-gpio-hsdk"; |
| reg = <0xf00014b0 0x4>; |
| gpio-controller; |
| #gpio-cells = <2>; |
| ngpios = <2>; |
| }; |
