From bf3ca248714b663455d0894557efd3a268797739 Mon Sep 17 00:00:00 2001 From: Stanislav Jakubek Date: Sun, 18 Jun 2023 17:13:08 +0200 Subject: [PATCH] dt-bindings: firmware: brcm,kona-smc: convert to YAML 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 Signed-off-by: Stanislav Jakubek Link: https://lore.kernel.org/r/20230618151308.GA23586@standask-GA-A55M-S2HP Signed-off-by: Florian Fainelli --- .../bindings/firmware/brcm,kona-smc.yaml | 39 ++++++++++++++++++++++ .../devicetree/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 0000000..684b15b --- /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 + +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 05b4723..0000000 --- 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 - }; -- 2.7.4
