Signed-off-by: Balakrishna Godavarthi Reviewed-by: Rob Herring --- Changes in v11: * removed entries of regulator currents. Changes in v10: * added entry for regulator currents Changes in v9: * updated with latest reg handle and names. * updated max-speed definition. Changes in v8: * Separated the optional entries between two chips Changes in v7: * no change. Changes in v6: * Changed the oper-speed to max-speed. Changes in v5: * Added entry for oper-speed and init-speed. --- .../bindings/net/qualcomm-bluetooth.txt | 26 +++++++++++++++++-- 1 file changed, 24 insertions(+), 2 deletions(-) diff --git a/Documentation/devicetree/bindings/net/qualcomm-bluetooth.txt b/Documentation/devicetree/bindings/net/qualcomm-bluetooth.txt index 0ea18a53cc29..2175174415ee 100644 --- a/Documentation/devicetree/bindings/net/qualcomm-bluetooth.txt +++ b/Documentation/devicetree/bindings/net/qualcomm-bluetooth.txt @@ -10,12 +10,22 @@ device the slave device is attached to.
