[PATCH 0/5] QEMU: Fix RISC-V virt & spike machines' dtbs

[Conor Dooley <mail@conchuod.ie>]

From: Conor Dooley <conor.dooley@microchip.com>

The device trees produced automatically for the virt and spike machines
fail dt-validate on several grounds. Some of these need to be fixed in
the linux kernel's dt-bindings, but others are caused by bugs in QEMU.
Patch one of this series is lifted from an earlier submission by Palmer
that seems to have got lost by the wayside somewhere along the way,
hence the rather out of date email used for Palmer [0].

I mostly opted for what appeared to be the smallest change that would
fix the warnings, partly due to my inexperience with the QEMU codebase.
A "sister" patchset for the kernel will clear the remaining warnings.

Thanks to Rob for reporting these issues [1],
Conor.

To reproduce the errors:
./build/qemu-system-riscv64 -nographic -machine virt,dumpdtb=qemu.dtb
dt-validate -p /path/to/linux/kernel/Documentation/devicetree/bindings/processed-schema.json qemu.dtb
(The processed schema needs to be generated first)
