Subject: usb: onboard-hub: Make i2c-bus optional
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=f4dd112a3822c86175d091362f5cce1029f0523b;p=thirdparty%2Fu-boot.git

usb: onboard-hub: Make i2c-bus optional

DT binding doesn't mandate i2c-bus as required property because hub itself
doesn't need to have i2c connected.
It can be in standalone mode that only power regulator and reset should be
handled.
Or hub should be configured via spi interface.
