From 20fd17ff35106d60f278c78bb783994c6747866b Mon Sep 17 00:00:00 2001 From: Robin Murphy Date: Wed, 7 Feb 2018 14:32:55 +0000 Subject: arm64: dts: juno: Describe the full GICv2m region Juno's GICv2m implementation consists of four frames providing 32 interrupts each. Since it is possible to plug in enough PCIe endpoints to consume more than 32 MSIs, and the driver already has a bodge to handle multiple frames, let's expose the other three as well.
