Subject: musb: sunxi: Allow host-side USB with external VBUS
X-Git-Url: http://git.dujemihanovic.xyz/html/static/gitweb.css?a=commitdiff_plain;h=9674c09b7495d15017b68a3d462b17040c12ff70;p=u-boot.git

musb: sunxi: Allow host-side USB with external VBUS

Now that the PHY driver will not try to drive VBUS if it is already
driven by an external supply, there is no need to check the VBUS voltage
before powering on the PHY.
