Subject: [PATCH v3 05/11] dmaengine: dw-axi-dmac: delay irq getting until request_irq
Date: Sun, 21 May 2023 18:12:10 +0800	[thread overview]
Message-ID: <20230521101216.4084-6-jszhang@kernel.org> (raw)
In-Reply-To: <20230521101216.4084-1-jszhang@kernel.org>

This is to prepare for per-channel irq support in next patch. In
per-channel irq case, we need to parse dt firstly to know whether
the platform is per-channel irq or not.
