From 9674c09b7495d15017b68a3d462b17040c12ff70 Mon Sep 17 00:00:00 2001 From: Samuel Holland Date: Thu, 14 Jul 2022 22:34:54 -0500 Subject: [PATCH] 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.
