Subject: [PATCH v3 10/12] dmaengine: at_xdmac: Fix at_xdmac_lld struct definition
Date: Wed, 15 Dec 2021 13:01:13 +0200 [thread overview]
Message-ID: <20211215110115.191749-11-tudor.ambarus@microchip.com> (raw)
In-Reply-To: <20211215110115.191749-1-tudor.ambarus@microchip.com>
The hardware channel next descriptor view structure contains just
fields of 32 bits, while dma_addr_t can be of type u64 or u32
depending on CONFIG_ARCH_DMA_ADDR_T_64BIT. Force u32 to comply with
what the hardware expects.
Fixes: e1f7c9eee707 ("dmaengine: at_xdmac: creation of the atmel eXtended DMA Controller driver")
