From mboxrd@z Thu Jan 1 00:00:00 1970 From: mperttunen@nvidia.com (Mikko Perttunen) Date: Mon, 2 Jul 2018 14:40:26 +0300 Subject: [PATCH v3 1/8] dt-bindings: tegra186-hsp: Add shared interrupts In-Reply-To: <20180702114033.15654-1-mperttunen@nvidia.com> References: <20180702114033.15654-1-mperttunen@nvidia.com> Message-ID: <20180702114033.15654-2-mperttunen@nvidia.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.
