Subject: [PATCH 11/11] arm: dts: vexpress: describe all PMUs in TC2 dts
Date: Fri,  7 Nov 2014 16:25:36 +0000	[thread overview]
Message-ID: <1415377536-12841-12-git-send-email-mark.rutland@arm.com> (raw)
In-Reply-To: <1415377536-12841-1-git-send-email-mark.rutland@arm.com>

The dts for the CoreTile Express A15x2 A7x3 (TC2) only describes the
PMUs of the Cortex-A15 CPUs, and not the Cortex-A7 CPUs.

Now that we have a mechanism for describing disparate PMUs and their
interrupts in device tree, this patch makes use of these to describe the
PMUs for all CPUs in the system.
