Subject: [PATCH 3/9] dt-bindings: tegra186-hsp: Add shared interrupts
Date: Fri, 26 Oct 2018 13:16:32 +0200	[thread overview]
Message-ID: <20181026111638.10759-4-thierry.reding@gmail.com> (raw)
In-Reply-To: <20181026111638.10759-1-thierry.reding@gmail.com>

From: Mikko Perttunen <mperttunen@nvidia.com>

HSP interrupts can be routed through exposed "shared interrupts". These
interrupts can be mapped to various internal interrupt lines. Add
interrupt properties for shared interrupts to the tegra186-hsp device
tree bindings.
