Add the yaml binding for available CPUs in MIPS architecture. Signed-off-by: Sergio Paracuellos <sergio.paracuellos@xxxxxxxxx> --- Changes in v2: - Remove 'bindings/mips/brcm/brcm,bmips.txt' - Include 'mips-hpt-frequency' in cpus YAML schema for bmips CPUS's - Add a BMIPS CPU node sample .../bindings/mips/brcm/brcm,bmips.txt | 8 -- .../devicetree/bindings/mips/cpus.yaml | 100 ++++++++++++++++++ 2 files changed, 100 insertions(+), 8 deletions(-) delete mode 100644 Documentation/devicetree/bindings/mips/brcm/brcm,bmips.txt create mode 100644 Documentation/devicetree/bindings/mips/cpus.yaml diff --git a/Documentation/devicetree/bindings/mips/brcm/brcm,bmips.txt b/Documentation/devicetree/bindings/mips/brcm/brcm,bmips.txt deleted file mode 100644 index 8ef71b4085ca..000000000000 --- a/Documentation/devicetree/bindings/mips/brcm/brcm,bmips.txt +++ /dev/null @@ -1,8 +0,0 @@ -* Broadcom MIPS (BMIPS) CPUs - -Required properties: -- compatible: "brcm,bmips3300", "brcm,bmips4350", "brcm,bmips4380", - "brcm,bmips5000" - -- mips-hpt-frequency: This is common to all CPUs in the system so it lives - under the "cpus" node. diff --git a/Documentation/devicetree/bindings/mips/cpus.yaml b/Documentation/devicetree/bindings/mips/cpus.yaml new file mode 100644 index 000000000000..361afde8ce0a --- /dev/null +++ b/Documentation/devicetree/bindings/mips/cpus.yaml @@ -0,0 +1,100 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/mips/cpus.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: MIPS CPUs bindings + +maintainers: + - Sergio Paracuellos <sergio.paracuellos@xxxxxxxxx> + +description: |+ + The device tree allows to describe the layout of CPUs in a system through + the "cpus" node, which in turn contains a number of subnodes (ie "cpu") + defining properties for every cpu. + +properties: + reg: + maxItems: 1 + + compatible: + enum: + - brcm,bmips3300 + - brcm,bmips4350 + - brcm,bmips4380 + - brcm,bmips5000 + - brcm,bmips5200 + - ingenic,xburst-mxu1.0 + - ingenic,xburst-fpu1.0-mxu1.1 + - ingenic,xburst-fpu2.0-mxu2.0 + - loongson,gs264 + - mips,mips1004Kc + - mips,m14Kc + - mips,mips24KEc + - mips,mips4KEc + - mips,mips74Kc + - mips,mips24Kc + - mti,mips24KEc + - mti,mips14KEc + - mti,mips14Kc + - mti,interaptiv + +if: + properties: + compatible: + enum: + - brcm,bmips3300 + - brcm,bmips4350 + - brcm,bmips4380 + - brcm,bmips5000 + - brcm,bmips5200 +then: + patternProperties: + mips-hpt-frequency: + $ref: /schemas/types.yaml#/definitions/uint32 + +required: + - compatible + +additionalProperties: true + +examples: + - | + cpus { + #size-cells = <0>; + #address-cells = <1>; + + cpu@0 { + device_type = "cpu"; + compatible = "mips,mips1004Kc"; + reg = <0>; + }; + + cpu@1 { + device_type = "cpu"; + compatible = "mips,mips1004Kc"; + reg = <1>; + }; + }; + + - | + // Example 2 (BMIPS CPU) + cpus { + #address-cells = <1>; + #size-cells = <0>; + + mips-hpt-frequency = <150000000>; + + cpu@0 { + compatible = "brcm,bmips4350"; + device_type = "cpu"; + reg = <0>; + }; + + cpu@1 { + compatible = "brcm,bmips4350"; + device_type = "cpu"; + reg = <1>; + }; + }; -- 2.25.1
