From 8665c18bece7965c3690ac3824bef2f97bae3d71 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Sat, 13 Jun 2015 14:37:51 +0200 Subject: phy-sun4i-usb: Add support for monitoring vbus via a power-supply On some boards there is no vbus_det gpio pin, instead vbus-detection for otg can be done via the pmic. This commit adds support for monitoring vbus_det via the power_supply exported by the pmic, enabling support for otg on these boards.
