| 3 | |
| 4 | Required properties: |
| 5 | - compatible : "st,comms-ssc4-spi" |
| 6 | - reg : Offset and length of the device's register set |
| 7 | - interrupts : The interrupt specifier |
| 8 | - clock-names : Must contain "ssc" |
| 9 | - clocks : Must contain an entry for each name in clock-names |
| 10 | See ../clk/* |
| 11 | - pinctrl-names : Uses "default", can use "sleep" if provided |
