1 | * Freescale MSI interrupt controller | ||
2 | |||
3 | Required properties: | ||
4 | - compatible : compatible list, contains 2 entries, | ||
5 | first is "fsl,CHIP-msi", where CHIP is the processor(mpc8610, mpc8572, | ||
6 | etc.) and the second is "fsl,mpic-msi" or "fsl,ipic-msi" depending on | ||
7 | the parent type. | ||
8 | - reg : should contain the address and the length of the shared message | ||
9 | interrupt register set. | ||
10 | - msi-available-ranges: use <start count> style section to define which | ||
11 | msi interrupt can be used in the 256 msi interrupts. This property is | ||
12 | optional, without this, all the 256 MSI interrupts can be used. | ||
13 | - interrupts : each one of the interrupts here is one entry per 32 MSIs, | ||
14 | and routed to the host interrupt controller. the interrupts should | ||
15 | be set as edge sensitive. | ||
16 | - interrupt-parent: the phandle for the interrupt controller | ||
17 | that services interrupts for this device. for 83xx cpu, the interrupts | ||
18 | are routed to IPIC, and for 85xx/86xx cpu the interrupts are routed | ||
19 | to MPIC. | ||
20 | |||

22 | msi@41600 { | ||
23 | compatible = "fsl,mpc8610-msi", "fsl,mpic-msi"; | ||
