Subject: [PATCH v5 01/23] dmaengine: ste_dma40: Fix physical cyclic capability
Date: Wed, 23 Sep 2026 01:30:46 +0200 [thread overview]
Message-ID: <20260923-dma40-fixes-v5-1-709d160cde76@kernel.org> (raw)
In-Reply-To: <20260923-dma40-fixes-v5-0-709d160cde76@kernel.org>
d40_dmaengine_init() configures dma_both for physical channels that can
handle both slave and memcpy transfers. Physical DMA40 channel setup has
supported cyclic LLIs since cyclic transfer support was added, but the
DMA_CYCLIC capability is set on dma_slave a second time instead of
dma_both.
Set DMA_CYCLIC on dma_both so d40_ops_init() installs
device_prep_dma_cyclic and physical channels advertise cyclic support.
Fixes: 0c842b551063 ("dma40: cyclic xfer support")
