| 2 | ----------------------- |
| 3 | |
| 4 | GICP is a Marvell extension of the GIC that allows to trigger GIC SPI |
| 5 | interrupts by doing a memory transaction. It is used by the ICU |
| 6 | located in the Marvell CP110 to turn wired interrupts inside the CP |
| 7 | into GIC SPI interrupts. |
| 8 | |
| 9 | Required properties: |
| 10 | |
| 11 | - compatible: Must be "marvell,ap806-gicp" |
| 12 | |
| 13 | - reg: Must be the address and size of the GICP SPI registers |
| 14 | |
| 15 | - marvell,spi-ranges: tuples of GIC SPI interrupts ranges available |
| 16 | for this GICP |
| 17 | |
| 18 | - msi-controller: indicates that this is an MSI controller |
| 19 | |
| 20 | Example: |
| 21 | |
| 22 | gicp_spi: gicp-spi@3f0040 { |
| 23 | compatible = "marvell,ap806-gicp"; |
| 24 | reg = <0x3f0040 0x10>; |
| 25 | marvell,spi-ranges = <64 64>, <288 64>; |
| 26 | msi-controller; |
| 27 | }; |
