Signed-off-by: Serge Semin Reviewed-by: Rob Herring --- Changelog v2: - Discard '|' in all the new properties, since we don't need to preserve the text formatting. - Convert abbreviated form of the "maximum-speed" enum restriction into the multi-lined version of the list. - Drop quotes from around the string constants. --- .../devicetree/bindings/usb/generic.txt | 57 ------------ .../devicetree/bindings/usb/usb-hcd.yaml | 88 +++++++++++++++++++ 2 files changed, 88 insertions(+), 57 deletions(-) delete mode 100644 Documentation/devicetree/bindings/usb/generic.txt diff --git a/Documentation/devicetree/bindings/usb/generic.txt b/Documentation/devicetree/bindings/usb/generic.txt deleted file mode 100644 index ba472e7aefc9..000000000000 --- a/Documentation/devicetree/bindings/usb/generic.txt +++ /dev/null @@ -1,57 +0,0 @@ -Generic USB Properties - -Optional properties: - - maximum-speed: tells USB controllers we want to work up to a certain - speed.
