From 826249942679a110353e71a1d92764fcf43e7cf7 Mon Sep 17 00:00:00 2001 From: Conor Dooley Date: Tue, 23 Aug 2022 19:33:17 +0100 Subject: [PATCH] dt-bindings: timer: sifive,clint: add legacy riscv compatible While "real" hardware might not use the compatible string "riscv,clint0" it is present in the driver & QEMU uses it for automatically generated virt machine dtbs. To avoid dt-validate problems with QEMU produced dtbs, such as the following, add it to the binding. riscv-virt.dtb: clint@2000000: compatible:0: 'sifive,clint0' is not one of ['sifive,fu540-c000-clint', 'starfive,jh7100-clint', 'canaan,k210-clint'] Reported-by: Rob Herring Link: https://lore.kernel.org/linux-riscv/20220803170552.GA2250266-robh@kernel.org/ Reviewed-by: Rob Herring Signed-off-by: Conor Dooley Reviewed-by: Heiko Stuebner Link: https://lore.kernel.org/r/20220823183319.3314940-2-mail@conchuod.ie Signed-off-by: Palmer Dabbelt --- .../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 ",-clint" and "sifive,clint". -- 2.34.1
