Subject: dmaengine: zx: set DMA_CYCLIC cap_mask bit
From: Shawn Guo <[email protected]>
[ Upstream commit fc318d64f3d91e15babac00e08354b1beb650b57 ]
The zx_dma driver supports cyclic transfer mode. Let's set DMA_CYCLIC cap_mask bit to make that clear, and avoid unnecessary failure when clients request channel via dma_request_chan_by_mask() with DMA_CYCLIC bit set in mask.
