X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=47f8ba232a17977f41c01e4f50934440f951395a;p=thirdparty%2Fkernel%2Flinux.git

dt-bindings: usb: maxim,max33359: Add supply property for vbus

Add a regulator supply property for vbus. This notifies the regulator
provider to source vbus when Type-C operates in Source power mode,
while turn off sourcing vbus when operating in Sink mode or
disconnected.
