SGIs are 0 to 15, PPIs are 16 to 31, and SPIs are 32+ - that's the numbering given to us by the GIC. > The real HW physical number start at 0, and thus this is that value that > should be in the irq binding of the device. That depends whether you're counting SPI number or whether you're counting IRQ number in the GIC interfaces. SPI0 will be reported to us from the GIC as 32, not 0, so to start numbering from 0 (which is already frowned upon for many reasons) we'd have to subtract 32 after checking that the IRQ is not a SGI nor PPI in the assembly code instead. _______________________________________________ devicetree-discuss mailing list devicetree-discuss@lists.ozlabs.org https://lists.ozlabs.org/listinfo/devicetree-discuss
