SubjectRe: [PATCH v2 0/2] Add support for bcm2711 in vchiq_arm

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@redhat.com/T/

Could you please explain your approach, especially leaving out 36 bit
DMA support?

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
