changes in v7:
1. Modify compatible as
- compatible : should be one of:
               "mediatek,mt2701-musb"
               ...
               followed by "mediatek,mtk-musb"
2. Change usb connector child node compatible as "gpio-usb-b-connector" 

changes in v6:
1. Modify usb connector child node

changes in v5:
suggested by Rob:
1. Modify compatible as 
- compatible : should be one of:
               "mediatek,mt-2701"
               ...
               followed by "mediatek,mtk-musb"
2. Add usb connector child node

changes in v4:
suggested by Sergei:
1. String alignment

changes in v3:
1. no changes

changes in v2:
suggested by Bin:
1. Modify DRC to DRD
suggested by Rob:
2. Drop the "<soc-model>-musb" in compatible
3. Remove phy-names
4. Add space after comma in clock-names

Please add Acked-by/Reviewed-by tags when posting new versions. However,
there's no need to repost patches *only* to add the tags. The upstream
maintainer will do that for acks received on the version they apply.

If a tag was not added on purpose, please state why and what changed.

+MediaTek musb DRD/OTG controller
+-------------------------------------------
+
+Required properties:
+ - compatible      : should be one of:
+                     "mediatek,mt2701-musb"
+                     ...
+                     followed by "mediatek,mtk-musb"
+ - reg             : specifies physical base address and size of
+                     the registers
+ - interrupts      : interrupt used by musb controller
+ - interrupt-names : must be "mc"
+ - phys            : PHY specifier for the OTG phy
+ - dr_mode         : should be one of "host", "peripheral" or "otg",
+                     refer to usb/generic.txt
+ - clocks          : a list of phandle + clock-specifier pairs, one for
+                     each entry in clock-names
+ - clock-names     : must contain "main", "mcu", "univpll"
+                     for clocks of controller
+
+Optional properties:
+ - power-domains   : a phandle to USB power domain node to control USB's
+                     MTCMOS
+
+Required child nodes:
+ usb connector node as defined in bindings/connector/usb-connector.txt
+Optional properties:
+ - id-gpios        : input GPIO for USB ID pin.
+ - vbus-gpios      : input GPIO for USB VBUS pin.
+ - vbus-supply     : reference to the VBUS regulator, needed when supports
+                     dual-role mode
+
+Example:
+
+usb2: usb@11200000 {
+	compatible = "mediatek,mt2701-musb",
+		     "mediatek,mtk-musb";
