1Marvell GICP Controller
2-----------------------
3
4GICP is a Marvell extension of the GIC that allows to trigger GIC SPI
5interrupts by doing a memory transaction. It is used by the ICU
6located in the Marvell CP110 to turn wired interrupts inside the CP
7into GIC SPI interrupts.
8
9Required 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
20Example:
21
22gicp_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};
