Convert to json-schema for the FSI-attached I2C controller. Signed-off-by: Eddie James <eajames@xxxxxxxxxxxxx> --- This patch was previously included in https://lore.kernel.org/all/20240429210131.373487-1-eajames@xxxxxxxxxxxxx/ Changes since v4: - Add patternProperties for the busses that will reference the i2c-controller schema, since the root node provides multiple i2c busses. Changes since v3: - Update MAINTAINERS - Change commit message to match similar commits .../devicetree/bindings/i2c/i2c-fsi.txt | 40 ---------- .../devicetree/bindings/i2c/ibm,i2c-fsi.yaml | 76 +++++++++++++++++++ MAINTAINERS | 2 +- 3 files changed, 77 insertions(+), 41 deletions(-) delete mode 100644 Documentation/devicetree/bindings/i2c/i2c-fsi.txt create mode 100644 Documentation/devicetree/bindings/i2c/ibm,i2c-fsi.yaml diff --git a/Documentation/devicetree/bindings/i2c/i2c-fsi.txt b/Documentation/devicetree/bindings/i2c/i2c-fsi.txt deleted file mode 100644 index b1be2ceb7e696..0000000000000 --- a/Documentation/devicetree/bindings/i2c/i2c-fsi.txt +++ /dev/null @@ -1,40 +0,0 @@ -Device-tree bindings for FSI-attached I2C master and busses ------------------------------------------------------------ - -Required properties: - - compatible = "ibm,i2c-fsi"; - - reg = < address size >; : The FSI CFAM address and address - space size. - - #address-cells = <1>; : Number of address cells in child - nodes. - - #size-cells = <0>; : Number of size cells in child nodes. - - child nodes : Nodes to describe busses off the I2C - master. - -Child node required properties: - - reg = < port number > : The port number on the I2C master. - -Child node optional properties: - - child nodes : Nodes to describe devices on the I2C - bus. - -Examples: - - i2c@1800 { - compatible = "ibm,i2c-fsi"; - reg = < 0x1800 0x400 >; - #address-cells = <1>; - #size-cells = <0>; - - i2c-bus@0 { - reg = <0>; - }; - - i2c-bus@1 { - reg = <1>; - - eeprom@50 { - compatible = "vendor,dev-name"; - }; - }; - }; diff --git a/Documentation/devicetree/bindings/i2c/ibm,i2c-fsi.yaml b/Documentation/devicetree/bindings/i2c/ibm,i2c-fsi.yaml new file mode 100644 index 0000000000000..62e70aaea9d56 --- /dev/null +++ b/Documentation/devicetree/bindings/i2c/ibm,i2c-fsi.yaml @@ -0,0 +1,76 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/i2c/ibm,i2c-fsi.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: IBM FSI-attached I2C controller + +maintainers: + - Eddie James <eajames@xxxxxxxxxxxxx> + +description: + This I2C controller is an FSI CFAM engine, providing access to a number of + I2C busses.
