| 4 | Required properties: |
| 5 | - compatible : Should be "cdns,i2c-r1p10" or "xlnx,zynq-spi-r1p10". |
| 6 | - reg : Physical base address and size of I2C registers map. |
| 7 | - interrupts : Property with a value describing the interrupt |
| 8 | number. |
| 9 | - interrupt-parent : Must be core interrupt controller |
| 10 | - clocks : Clock phandles (see clock bindings for details). |
