| Nordic nRF GPIO pad group. |
| |
| The GPIO pad group describes the pads (package |
| pins of the SoC) the GPIO controller manages. |
| |
| The pads may be in a different power domain than |
| the GPIO controller, and may require enabling |
| retention to preserve the GPIO configuration if |
| the power domain is suspended. |
| |
| The GPIO pad group is a child node of the GPIO |
| controller which manages the pad group, named |
| pad-group. The pad group's nodelabel is named |
| gpio_pad_group<GPIO number>. |
| |
| Example layout: |
| |
| gpio0: gpio@938000 { |
| compatible = "nordic,nrf-gpio"; |
| |
| ... |
| |
| gpio_pad_group0: pad-group { |
| compatible = "nordic,nrf-gpio-pad-group"; |
| power-domains = <&gdpwr_slow_main>; |
| retain-mask = <0xFFF>; |
| }; |
| }; |
| |
| compatible: "nordic,nrf-gpio-pad-group" |

| Mask of pins which shall be retained if pad |
| group's power domain is powered off. |
