| WUCs are mapped to the pins of GPIO. |
| The WUC groups internal and external inputs, and asserts |
| a wake-up signal to the INTC, allowing the CPU to exit |
| Doze/Deep Doze/Sleep modes. |

| type: boolean |
| description: | |
| When set, this GPIO controller has pins associated with the |
| keyboard controller. In this case the reg_gpcr property is |
| overloaded and used to write the keyboard GCTRL register. |
| This setting will be found in the gpio_ite_configure function |
| when the judgment of gpio_config->ksb_ctrl is true. |
| The GPIO control register that will be set for these three |
| nodes is as follows: |
| gpioksi: 0xf01d40-0xf01d47 |
| gpioksol: 0xf01d48-0xf01d4f |
| gpioksoh: 0xf01d50-0xf01d57 |

| gpio-cells: |
| - pin |
| - flags |
