I have been trying to figure out what is the vector number used for external
IRQ4 and IRQ5 in P4080ds.
According to board document xpedite5470-p4080
IRQ4: VPX GP Input 0 (GPI0)
IRQ5 VPX GP Input 1 (GPI1)
In p4080 user guide OpenPIC interrupt connection its mentioned as
IRQ4_B: SLOT4 Sideband connector (SGMII riser does not connect, XAUI riser
can use or inband)
IRQ5_B: MIC2076 USB Power FLAG for over current at USB connector
But in code i am unable to find any info related to IRQ4 and IRQ5.
How can i find??
Thanks
Lakshmi

Are you asking what to put in the device tree for these interrupts? External
IRQ4 is <4 ls 0 0> and IRQ5 is <5 ls 0 0>, with ls being the level/sense info.
See Documentation/devicetree/bindings/powerpc/fsl/mpic.txt for details.
