Acked-by: Conor Dooley Reviewed-by: Rob Herring (Arm) Signed-off-by: Ryan Chen --- Changes in v29: - remove aspeed,enable-dma properties. Changes in v28: - update commit message correspond with aspeed,enable-dma. - remove aspeed,transfer-mode and add aspeed,enable-dma property and description. - Fix aspeed,enable-dma description to reflect hardware capability rather than software behavior Changes in v27: - change aspeed,transfer-mode to aspeed,enable-dma. --- Documentation/devicetree/bindings/i2c/aspeed,ast2600-i2c.yaml | 7 +++++++ 1 file changed, 7 insertions(+) diff --git a/Documentation/devicetree/bindings/i2c/aspeed,ast2600-i2c.yaml b/Documentation/devicetree/bindings/i2c/aspeed,ast2600-i2c.yaml index abc614315dff..21469715d845 100644 --- a/Documentation/devicetree/bindings/i2c/aspeed,ast2600-i2c.yaml +++ b/Documentation/devicetree/bindings/i2c/aspeed,ast2600-i2c.yaml @@ -48,6 +48,12 @@ properties: resets: maxItems: 1 + aspeed,global-regs: + $ref: /schemas/types.yaml#/definitions/phandle + description: + Phandle reference to the i2c global syscon node, containing the + SoC-common i2c register set. + required: - reg - compatible @@ -70,4 +76,5 @@ examples: resets = <&syscon ASPEED_RESET_I2C>; clock-frequency = <100000>; interrupts = ; + aspeed,global-regs = <&i2c_global>; }; -- 2.34.1
