This adds formal validation and improves documentation using a conditional schema. Remove the twl4030 section from the obsolete .txt binding file Signed-off-by: Jihed Chaibi --- Changes in v7: - Removed the twl4030 section from the obsolete .txt binding file Changes in v6: - Reworked 'interrupts' property to use a list of items with descriptions instead of a single free-form text block. Changes in v5: - Split combined twlxxxx-usb binding into a dedicated file for twl4030-usb per maintainer feedback. - Used more accurate header for interrupt macros. - Improved formatting in the examples. Changes in v4: - This patch is split from larger series per maintainer feedback. - v3 link: https://lore.kernel.org/all/20250816021523.167049-1-jihed.chaibi.dev@gmail.com/ - Removed i2c node as it wasn't required by the old binding file. - Updated node names to 'usb' and 'usb-phy' in the examples to follow generic naming conventions per the Device Tree specification. - Replaced raw interrupt values with standard defines for clarity. - Improved formatting in the examples for clarity and consistency. Changes in v3: - No changes. Changes in v2: - Added '#phy-cells' property to support PHY framework integration. --- .../bindings/usb/ti,twl4030-usb.yaml | 74 +++++++++++++++++++ .../devicetree/bindings/usb/twlxxxx-usb.txt | 22 ------ 2 files changed, 74 insertions(+), 22 deletions(-) create mode 100644 Documentation/devicetree/bindings/usb/ti,twl4030-usb.yaml diff --git a/Documentation/devicetree/bindings/usb/ti,twl4030-usb.yaml b/Documentation/devicetree/bindings/usb/ti,twl4030-usb.yaml new file mode 100644 index 000000000000..6ef337507425 --- /dev/null +++ b/Documentation/devicetree/bindings/usb/ti,twl4030-usb.yaml @@ -0,0 +1,74 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/usb/ti,twl4030-usb.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Texas Instruments TWL4030 USB PHY and Comparator + +maintainers: + - Peter Ujfalusi + +description: + Bindings for the USB PHY and comparator module found within the + TWL4030 family of companion chips.
