The goal of this patch series is to use the bcm2711 compatible string in
vchiq_arm for the Raspberry Pi 4.
there was already a patch series to enable VCHIQ on BCM2711, which
wasn't accepted:
https://lore.kernel.org/linux-arm-kernel/20211014223230.451659-1-mguma@xxxxxxxxxx/T/
Could you please explain your approach, especially leaving out 36 bit
DMA support?
This allows using the downstream device
tree with the upstream kernel.
This is a really bad idea and caused a lot of trouble in the past. A lot
of the issues in the Fedora or Arch Linux forums or mailing lists
results from this idea. It wastes the time of the kernel developer since
these DT files has never been reviewed by the devicetree maintainers.
Best regards
