The RISC-V ISA mandantes the presence of a simple, per-hart (hardware thread) interrupt controller availiable to supervisor mode. This patch set adds a driver for this interrupt controller. The patch set itself has been around in various flavors for a while, but as far as I remember it's never been properly cleaned up and submitted before. As it currently stands it's essentially three seperate patches, but as they're all intertwined I'm keeping them together. Sorry if that's the wrong thing to do. The patches are: * A cleanup to arch/riscv to remove a bit of the old initialization mechanism that snuck in to our arch port. This patch is trivial, so unless there's any feedback on it specificly I'll include it in my next pull request. * The addition of device tree bindings to describe "riscv,cpu-intc". * The actual irqchip driver. If this gets merged before the arch/riscv patch then it'll cause our build to fail, but I'm assuming this will be targeted at the next merge window so we should be safe. -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
