Please ignore this series, I accidentally had too much in the folder.

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. Patches been sent that fix the QEMU issues [0], but a couple of them need to be fixed in the kernel's dt-bindings. The first patches add compatibles for "riscv,{clint,plic}0" which are present in drivers and the auto generated QEMU dtbs. The final patch should be ignored for all serious purposes unless you want to wash your eyes out afterwards, but JIC the versioned extensions ever come up, it's there. Thanks to Rob Herring for reporting these issues [1], Conor.
