Subject: [PATCH v5 4/6] ARM: tegra: update DTs to expose legacy interrupt controller
Date: Mon, 23 Feb 2015 17:43:40 +0000 [thread overview]
Message-ID: <1424713422-6688-5-git-send-email-marc.zyngier@arm.com> (raw)
In-Reply-To: <1424713422-6688-1-git-send-email-marc.zyngier@arm.com>
Describe the legacy interrupt controller in every tegra DTSI files,
and make it the parent of most interrupts.
