From: Conor Dooley <conor.dooley@microchip.com>
The QEMU virt and spike machines currently export a riscv,isa string of "rv64imafdcsuh", but this obviously has illegal extensions in it. The presense of "su" is a QEMU bug, so add an entry for the valid portion of the isa string.
Reported-by: Rob Herring <robh@kernel.org> Link: https://lore.kernel.org/linux-riscv/20220803170552.GA2250266-robh@kernel.org/ Signed-off-by: Conor Dooley <conor.dooley@microchip.com> --- Although the commit message says "a" string, I have added more than one isa string. My patched version of QEMU emits the full string with the multi letter extensions and I am not sure what the policy is for including them in the binding. Obviously I am more than willing to change the patch text if needed. --- Documentation/devicetree/bindings/riscv/cpus.yaml | 2 ++ 1 file changed, 2 insertions(+)
