I think with the new code of yours:
mas->tx = dma_request_slave_channel(mas->dev, "tx");
+ if (IS_ERR_OR_NULL(mas->tx)) {

Hi,
looks like sdm845-cheza also uses the spi0 bus, which as far as I understand is
going to break with the GPI DMA disabled. Perhaps it should also be enabled
over there?
Actually, is there a point in disabling DMA for BLSPs/QUPs in the SoC DTSI? I
don't think any platform/vendor firmware dis
Add dmas property for spi@88 and pinconf setting so that we can use
dma for this spi device. Also, add iommu properties for qup and spi.
