Hi, since v5.11-rc6 my Pinephone display shows some moiré pattern. I did a bisect between v5.11-rc5 and v5.11-rc6 and it told me that the commit mentioned in the subject is the reason.
Reverting it makes the display work again and re-reverting fail again. IMHO it seems as if the display DMA of the pinephone (allwinner suni-a54) got influenced and stopped to scan the framebuffer. The only dma-ranges I could find are defined here: arch/arm64/boot/dts/allwinner/sun50i-a64.dtsi dma-ranges = <0x00000000 0x40000000 0xc0000000>; but I can't tell if they are "valid" or not. Any insights are welcome. And please direct to the right people/mailing lists if they are missing. BR and thanks, Nikolaus Schaller
