Subject: [PATCH v12 7/8] dt-bindings: PCI: qcom: Support additional MSI interrupts
Date: Mon, 23 May 2022 21:18:35 +0300	[thread overview]
Message-ID: <20220523181836.2019180-8-dmitry.baryshkov@linaro.org> (raw)
In-Reply-To: <20220523181836.2019180-1-dmitry.baryshkov@linaro.org>

On Qualcomm platforms each group of 32 MSI vectors is routed to the
separate GIC interrupt. Document mapping of additional interrupts.
