Convert Broadcom Kona family I2C bindings to DT schema. Changes during conversion: - add used, but previously undocumented SoC-specific compatibles - drop references to SoCs that are not upstream - add supported clock frequencies according to the Linux driver [1] [1] https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/tree/drivers/i2c/busses/i2c-bcm-kona.c#n731 Signed-off-by: Stanislav Jakubek <stano.jakubek@xxxxxxxxx> --- Changes in v2: - add missing arm-gic.h include - fix indentation to 4 spaces .../devicetree/bindings/i2c/brcm,kona-i2c.txt | 35 ----------- .../bindings/i2c/brcm,kona-i2c.yaml | 59 +++++++++++++++++++ 2 files changed, 59 insertions(+), 35 deletions(-) delete mode 100644 Documentation/devicetree/bindings/i2c/brcm,kona-i2c.txt create mode 100644 Documentation/devicetree/bindings/i2c/brcm,kona-i2c.yaml diff --git a/Documentation/devicetree/bindings/i2c/brcm,kona-i2c.txt b/Documentation/devicetree/bindings/i2c/brcm,kona-i2c.txt deleted file mode 100644 index 1b87b741fa8e..000000000000 --- a/Documentation/devicetree/bindings/i2c/brcm,kona-i2c.txt +++ /dev/null @@ -1,35 +0,0 @@ -Broadcom Kona Family I2C -========================= - -This I2C controller is used in the following Broadcom SoCs: - - BCM11130 - BCM11140 - BCM11351 - BCM28145 - BCM28155 - -Required Properties -------------------- -- compatible: "brcm,bcm11351-i2c", "brcm,kona-i2c" -- reg: Physical base address and length of controller registers -- interrupts: The interrupt number used by the controller -- clocks: clock specifier for the kona i2c external clock -- clock-frequency: The I2C bus frequency in Hz -- #address-cells: Should be <1> -- #size-cells: Should be <0> - -Refer to clocks/clock-bindings.txt for generic clock consumer -properties. - -Example: - -i2c@3e016000 { - compatible = "brcm,bcm11351-i2c","brcm,kona-i2c"; - reg = <0x3e016000 0x80>; - interrupts = <GIC_SPI 103 IRQ_TYPE_LEVEL_HIGH>; - clocks = <&bsc1_clk>; - clock-frequency = <400000>; - #address-cells = <1>; - #size-cells = <0>; -}; diff --git a/Documentation/devicetree/bindings/i2c/brcm,kona-i2c.yaml b/Documentation/devicetree/bindings/i2c/brcm,kona-i2c.yaml new file mode 100644 index 000000000000..7a694af90fc6 --- /dev/null +++ b/Documentation/devicetree/bindings/i2c/brcm,kona-i2c.yaml @@ -0,0 +1,59 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/i2c/brcm,kona-i2c.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Broadcom Kona family I2C controller + +maintainers: + - Florian Fainelli <f.fainelli@xxxxxxxxx> + +allOf: + - $ref: /schemas/i2c/i2c-controller.yaml# + +properties: + compatible: + items: + - enum: + - brcm,bcm11351-i2c + - brcm,bcm21664-i2c + - brcm,bcm23550-i2c + - const: brcm,kona-i2c + + reg: + maxItems: 1 + + interrupts: + maxItems: 1 + + clocks: + maxItems: 1 + + clock-frequency: + enum: [ 100000, 400000, 1000000, 3400000 ] + +required: + - compatible + - reg + - interrupts + - clocks + - clock-frequency + +unevaluatedProperties: false + +examples: + - | + #include <dt-bindings/interrupt-controller/arm-gic.h> + #include <dt-bindings/interrupt-controller/irq.h> + + i2c@3e016000 { + compatible = "brcm,bcm11351-i2c", "brcm,kona-i2c"; + reg = <0x3e016000 0x80>; + interrupts = <GIC_SPI 103 IRQ_TYPE_LEVEL_HIGH>; + clocks = <&bsc1_clk>; + clock-frequency = <400000>; + #address-cells = <1>; + #size-cells = <0>; + }; +... -- 2.25.1
