Subject: [PATCH] spi: dt-bindings: samsung: make dma properties not required
Date: Fri, 1 Mar 2024 11:55:46 +0000 [thread overview]
Message-ID: <20240301115546.2266676-1-tudor.ambarus@linaro.org> (raw)
Since the addition of the driver in 2009, the driver selects between DMA
and polling mode depending on the transfer length - DMA mode for
transfers bigger than the FIFO depth, polling mode otherwise. All
versions of the IP support polling mode, make the dma properties not
required.
