Subject: dm: usb: Pass EHCI controller pointer to ehci_set_usbmode()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=11d18a1946bd290b83d584ab521e6940e1a11d69;p=project%2Fbcm63xx%2Fu-boot.git

dm: usb: Pass EHCI controller pointer to ehci_set_usbmode()

Adjust this function so that it is passed an EHCI controller pointer so that
implementations can look up their controller. This makes the weak functions
use a consistent API.
