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.
I am even checking the ret value here, so if it can't set it, it will
log an error. I don't that getting logged on my end. Can you share you
entire dmesg output please?
Sure, see below
Also, I have tested this against arm64 kernel, I assume you are using
32-bit?
Correct. This is what i meant with multi_v7_defconfig. It's my prefered
configuration to test BCM2837 for 32 bit ARM.
In the old platform driver code we had something like
pdevinfo.dma_mask = DMA_BIT_MASK(32);
So there is still something missing for our new bus driver.
