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 disables entire hosts..
