To avoid dt-validate problems with QEMU produced dtbs, such as the following, add it to the binding. riscv-virt.dtb: clint@...0000: compatible:0: 'sifive,clint0' is not one of ['sifive,fu540-c000-clint', 'starfive,jh7100-clint', 'canaan,k210-clint'] Reported-by: Rob Herring <robh@...nel.org> Link: https://lore.kernel.org/linux-riscv/20220803170552.GA2250266-robh@kernel.org/ Signed-off-by: Conor Dooley <conor.dooley@...rochip.com> --- .../bindings/timer/sifive,clint.yaml | 18 ++++++++++++------ 1 file changed, 12 insertions(+), 6 deletions(-) diff --git a/Documentation/devicetree/bindings/timer/sifive,clint.yaml b/Documentation/devicetree/bindings/timer/sifive,clint.yaml index e64f46339079..bbad24165837 100644 --- a/Documentation/devicetree/bindings/timer/sifive,clint.yaml +++ b/Documentation/devicetree/bindings/timer/sifive,clint.yaml @@ -22,12 +22,18 @@ description: properties: compatible: - items: - - enum: - - sifive,fu540-c000-clint - - starfive,jh7100-clint - - canaan,k210-clint - - const: sifive,clint0 + oneOf: + - items: + - enum: + - sifive,fu540-c000-clint + - starfive,jh7100-clint + - canaan,k210-clint + - const: sifive,clint0 + - items: + - const: sifive,clint0 + - const: riscv,clint0 + deprecated: true + description: For the QEMU virt machine only description: Should be "<vendor>,<chip>-clint" and "sifive,clint<version>". -- 2.37.1
