Convert the existing text-based DT bindings for Marvell 8897/8997 (sd8897/sd8997) bluetooth devices controller to a YAML schema.
While here, bindings for "usb1286,204e" (USB interface) are dropped from the YAML definition as these are currently documented in file: - Documentation/devicetree/bindings/net/btusb.txt Signed-off-by: Ariel D'Alessandro <ariel.dalessan...@collabora.com> --- .../bindings/net/marvell,sd8897-bt.yaml | 91 +++++++++++++++++++ .../bindings/net/marvell-bt-8xxx.txt | 83 ----------------- 2 files changed, 91 insertions(+), 83 deletions(-) create mode 100644 Documentation/devicetree/bindings/net/marvell,sd8897-bt.yaml delete mode 100644 Documentation/devicetree/bindings/net/marvell-bt-8xxx.txt diff --git a/Documentation/devicetree/bindings/net/marvell,sd8897-bt.yaml b/Documentation/devicetree/bindings/net/marvell,sd8897-bt.yaml new file mode 100644 index 0000000000000..6539868c08b8a --- /dev/null +++ b/Documentation/devicetree/bindings/net/marvell,sd8897-bt.yaml @@ -0,0 +1,91 @@ +# SPDX-License-Identifier: (GPL-2.0 OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/net/marvell,sd8897-bt.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Marvell 8897/8997 (sd8897/sd8997) bluetooth devices (SDIO) + +maintainers: + - Ariel D'Alessandro <ariel.dalessan...@collabora.com> + +properties: + compatible: + enum: + - marvell,sd8897-bt + - marvell,sd8997-bt + + reg: + maxItems: 1 + + interrupts: + maxItems: 1 + + marvell,cal-data: + $ref: /schemas/types.yaml#/definitions/uint8-array + description: + Calibration data downloaded to the device during initialization. + minItems: 28 + + marvell,wakeup-pin: + $ref: /schemas/types.yaml#/definitions/uint16 + description: + Wakeup pin number of the bluetooth chip.
