From 9ca8dbcc65cfc63d6f5ef3312a33184e1d726e00 Mon Sep 17 00:00:00 2001 From: Yunhong Jiang Date: Tue, 4 Aug 2015 12:17:53 -0700 Subject: Add the rt linux 4.1.3-rt3 as base Import the rt linux 4.1.3-rt3 as OPNFV kvm base. It's from git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git linux-4.1.y-rt and the base is: commit 0917f823c59692d751951bf5ea699a2d1e2f26a2 Author: Sebastian Andrzej Siewior Date: Sat Jul 25 12:13:34 2015 +0200 Prepare v4.1.3-rt3 Signed-off-by: Sebastian Andrzej Siewior We lose all the git history this way and it's not good. We should apply another opnfv project repo in future.

It +is also referred to as "WUGEN-MPU", hence the name of the binding. + +Reguired properties: + +- compatible : should contain at least "ti,omap4-wugen-mpu" or + "ti,omap5-wugen-mpu" +- reg : Specifies base physical address and size of the registers. +- interrupt-controller : Identifies the node as an interrupt controller. +- #interrupt-cells : Specifies the number of cells needed to encode an + interrupt source. The value must be 3. +- interrupt-parent : a phandle to the GIC these interrupts are routed + to. + +Notes: + +- Because this HW ultimately routes interrupts to the GIC, the + interrupt specifier must be that of the GIC. +- Only SPIs can use the WUGEN as an interrupt parent.
