[PATCH 11/25] dt-bindings: spi: andestech,ae350-spi: make DMA and interrupts optional
From: Benoît Monin
Date: Fri Nov 06 2026 - 04:37:34 EST
The ATCSPI200 controller can be used in PIO mode, without DMA, and PIO
transfers can optionally use the controller's interrupt. Make dmas,
dma-names and interrupts optional, and require dma-names if dmas is
specified.
