Add device tree binding document for Maxim 33359 Type-C chip driver Signed-off-by: Badhri Jagan Sridharan <badhri@google.com> --- Changes since v1: - Changing patch version to v6 to fix version number confusion. Changes since v6: - Migrated to yaml format. Changes since v7: - Rebase on usb-next Changes since v8: - Fix errors from make dt_binding_check as suggested by Rob Herring. Changes since v9: - additionalProperties: false as suggested by Rob Herring. Changes since v10: - Added the chip number to the binding as suggested by Rob Herring. - Renamed the filename as well. --- .../devicetree/bindings/usb/maxim,33359.yaml | 75 +++++++++++++++++++ 1 file changed, 75 insertions(+) create mode 100644 Documentation/devicetree/bindings/usb/maxim,33359.yaml
