Unfortunately the call of of_dma_configure() generates warnings likes
this (Raspberry Pi 3A+ with multi_v7_defconfig + VCHIQ):
[ 9.206802] vchiq-bus bcm2835-audio: DMA mask not set
[ 9.206892] vchiq-bus bcm2835-camera: DMA mask not set
huh, really weird, as on my RPi-3-b I get these set correctly and I
don't any such warning.
This warning comes from this line [1]. Did you test with the mainline
devicetree from [2] which must be specified in the config.txt? Be
aware the arm dts files has moved into a sub directory just like
arm64. I don't use U-Boot, just the vendor bootloader from Raspberry
Pi OS. Please look at [3] for the details.
please look at [4], which is possible a solution. AFAIK the dwc2 also
had the same problem.
