1 | * Microchip WILC wireless SDIO device |
| 2 | ||
| 3 | The wilc1000 chips can be connected via SDIO. The node is used to specifiy | |
| 4 | child node to the SDIO controller that connects the device to the system. | |
| 5 | ||
| 6 | Required properties: | |
| 7 | - compatible : Should be "microchip,wilc1000-spi" | |
| 8 | - irq-gpios : Connect to a host IRQ | |
| 9 | - reg : Slot ID used in the controller | |
| 10 | ||
| 11 | Optional: | |
| 12 | - bus-width : Number of data lines wired up the slot. Default 1 bit. | |

13 | - rtc_clk : Clock connected on the rtc clock line. Must be assigned |
| 14 | a frequency with assigned-clocks property, and must be | |
