Convert old text based binding to json schema. Changes during conversion: Add a missing fallback `atmel,at91sam9x5-matrix` for `microchip,sam9x60-matrix` which is not defined in the text binding. Signed-off-by: Charan Pedumuru <charan.pedumuru@xxxxxxxxxxxxx> --- Changes in v2: - Modified the commit messsage. - Replaced `anyOf` with `oneOf` in compatible under properties. - Removed additional items group and added both `microchip,sam9x60-matrix` and `microchip,sam9x7-matrix` as an enum under one items group - Replaced `matrix@` with `syscon@` in examples. - Link to v1: https://lore.kernel.org/r/20241211-matrix-v1-1-5ef0104a3af4@xxxxxxxxxxxxx --- .../bindings/mfd/atmel,at91sam9260-matrix.yaml | 52 ++++++++++++++++++++++ .../devicetree/bindings/mfd/atmel-matrix.txt | 26 ----------- 2 files changed, 52 insertions(+), 26 deletions(-) diff --git a/Documentation/devicetree/bindings/mfd/atmel,at91sam9260-matrix.yaml b/Documentation/devicetree/bindings/mfd/atmel,at91sam9260-matrix.yaml new file mode 100644 index 000000000000..447b3a3edbfc --- /dev/null +++ b/Documentation/devicetree/bindings/mfd/atmel,at91sam9260-matrix.yaml @@ -0,0 +1,52 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/mfd/atmel,at91sam9260-matrix.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Microchip AT91 Bus Matrix + +maintainers: + - Nicolas Ferre <nicolas.ferre@xxxxxxxxxxxxx> + +description: + The Bus Matrix (MATRIX) implements a multi-layer AHB, based on the + AHB-Lite protocol, that enables parallel access paths between multiple + masters and slaves in a system, thus increasing the overall bandwidth. + +properties: + compatible: + oneOf: + - items: + - enum: + - atmel,at91sam9260-matrix + - atmel,at91sam9261-matrix + - atmel,at91sam9263-matrix + - atmel,at91sam9rl-matrix + - atmel,at91sam9g45-matrix + - atmel,at91sam9n12-matrix + - atmel,at91sam9x5-matrix + - atmel,sama5d3-matrix + - const: syscon + - items: + - enum: + - microchip,sam9x60-matrix + - microchip,sam9x7-matrix + - const: atmel,at91sam9x5-matrix + - const: syscon + + reg: + maxItems: 1 + +required: + - compatible + - reg + +additionalProperties: false + +examples: + - | + syscon@ffffec00 { + compatible = "atmel,sama5d3-matrix", "syscon"; + reg = <0xffffec00 0x200>; + }; diff --git a/Documentation/devicetree/bindings/mfd/atmel-matrix.txt b/Documentation/devicetree/bindings/mfd/atmel-matrix.txt deleted file mode 100644 index 6e5f83614e83..000000000000 --- a/Documentation/devicetree/bindings/mfd/atmel-matrix.txt +++ /dev/null @@ -1,26 +0,0 @@ -* Device tree bindings for Atmel Bus Matrix - -The Bus Matrix registers are used to configure Atmel SoCs internal bus -behavior (master/slave priorities, undefined burst length type, ...) - -Required properties: -- compatible: Should be one of the following - "atmel,at91sam9260-matrix", "syscon" - "atmel,at91sam9261-matrix", "syscon" - "atmel,at91sam9263-matrix", "syscon" - "atmel,at91sam9rl-matrix", "syscon" - "atmel,at91sam9g45-matrix", "syscon" - "atmel,at91sam9n12-matrix", "syscon" - "atmel,at91sam9x5-matrix", "syscon" - "atmel,sama5d3-matrix", "syscon" - "microchip,sam9x60-matrix", "syscon" - "microchip,sam9x7-matrix", "atmel,at91sam9x5-matrix", "syscon" -- reg: Contains offset/length value of the Bus Matrix - memory region. - -Example: - -matrix: matrix@ffffec00 { - compatible = "atmel,sama5d3-matrix", "syscon"; - reg = <0xffffec00 0x200>; -}; --- base-commit: 1b2ab8149928c1cea2d7eca30cd35bb7fe014053 change-id: 20241210-matrix-30021676fb6f Best regards, -- Charan Pedumuru <charan.pedumuru@xxxxxxxxxxxxx>
