From 03e607cbb2931374db1825f371e9c7f28526d3f4 Mon Sep 17 00:00:00 2001 From: Sean Anderson Date: Mon, 25 Apr 2022 13:14:09 -0400 Subject: [PATCH] usb: phy: generic: Get the vbus supply While support for working with a vbus was added, the regulator was never actually gotten (despite what was documented). Fix this by actually getting the supply from the device tree.
