Convert Broadcom Kona family Secure Monitor bounce buffer bindings to DT schema. Changes during conversion: - move from misc to firmware subdirectory - add used, but previously undocumented SoC-specific compatibles - drop deprecated compatibles (they've been deprecated for ~10 years) Reviewed-by: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx> Signed-off-by: Stanislav Jakubek <stano.jakubek@xxxxxxxxx> --- Changes in V4: - collect Krzysztof's R-b - rebase on next-20230616 Changes in V3: - remove unnecessary oneOf (Krzysztof) Changes in V2: - move to firmware subdirectory (Krzysztof) - drop deprecated compatibles (Krzysztof) - adjusted commit message to reflect the above changes .../bindings/firmware/brcm,kona-smc.yaml | 39 +++++++++++++++++++ .../bindings/misc/brcm,kona-smc.txt | 15 ------- 2 files changed, 39 insertions(+), 15 deletions(-) create mode 100644 Documentation/devicetree/bindings/firmware/brcm,kona-smc.yaml delete mode 100644 Documentation/devicetree/bindings/misc/brcm,kona-smc.txt diff --git a/Documentation/devicetree/bindings/firmware/brcm,kona-smc.yaml b/Documentation/devicetree/bindings/firmware/brcm,kona-smc.yaml new file mode 100644 index 000000000000..684b15ba9ad0 --- /dev/null +++ b/Documentation/devicetree/bindings/firmware/brcm,kona-smc.yaml @@ -0,0 +1,39 @@ +# SPDX-License-Identifier: GPL-2.0-only OR BSD-2-Clause +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/firmware/brcm,kona-smc.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Broadcom Kona family Secure Monitor bounce buffer + +description: + A bounce buffer used for non-secure to secure communications. + +maintainers: + - Florian Fainelli <f.fainelli@xxxxxxxxx> + +properties: + compatible: + items: + - enum: + - brcm,bcm11351-smc + - brcm,bcm21664-smc + - brcm,bcm23550-smc + - const: brcm,kona-smc + + reg: + maxItems: 1 + +required: + - compatible + - reg + +additionalProperties: false + +examples: + - | + smc@3404c000 { + compatible = "brcm,bcm11351-smc", "brcm,kona-smc"; + reg = <0x3404c000 0x400>; /* 1 KiB in SRAM */ + }; +... diff --git a/Documentation/devicetree/bindings/misc/brcm,kona-smc.txt b/Documentation/devicetree/bindings/misc/brcm,kona-smc.txt deleted file mode 100644 index 05b47232ed9e..000000000000 --- a/Documentation/devicetree/bindings/misc/brcm,kona-smc.txt +++ /dev/null @@ -1,15 +0,0 @@ -Broadcom Secure Monitor Bounce buffer ------------------------------------------------------ -This binding defines the location of the bounce buffer -used for non-secure to secure communications. - -Required properties: -- compatible : "brcm,kona-smc" -- DEPRECATED: compatible : "bcm,kona-smc" -- reg : Location and size of bounce buffer - -Example: - smc@3404c000 { - compatible = "brcm,bcm11351-smc", "brcm,kona-smc"; - reg = <0x3404c000 0x400>; //1 KiB in SRAM - }; -- 2.25.1
