This commit adds the Device Tree binding documentation for the Marvell GICP, an extension to the GIC that allows to trigger GIC SPI interrupts using memory transactions. It is used by the ICU unit in the Marvell CP110 block to turn wired interrupts inside the CP into SPI interrupts at the GIC level in the AP.Sounds like an MSI block?
Almost. It also allows to deal with level interrupts, which a classic MSI controller cannot manage. This looks like it has been lifted from the GICv3 spec, which offers the exact same mechanism for SPIs. Thanks, M. -- Jazz is not dead.
