Subject: [PATCH v12 13/17] dmaengine: dw-axi-dmac: Add Intel KeemBay AxiDMA support
Date: Mon, 25 Jan 2021 09:32:51 +0800 [thread overview]
Message-ID: <20210125013255.25799-14-jee.heng.sia@intel.com> (raw)
In-Reply-To: <20210125013255.25799-1-jee.heng.sia@intel.com>
Add support for Intel KeemBay AxiDMA to the .compatible field.
The AxiDMA Apb region will be accessible if the compatible string
matches the "intel,kmb-axi-dma".
