Subject: [PATCHv2 1/1] ARM: dts: meson8b: odroidc1: fix USB power supplies for phy
Date: Sat,  9 Feb 2019 17:54:28 +0000	[thread overview]
Message-ID: <20190209175428.1199-2-linux.amoon@gmail.com> (raw)
In-Reply-To: <20190209175428.1199-1-linux.amoon@gmail.com>

From the shematics GPIOAO.BIT5 gpio input for the PWREN signal of the
USB_HOST controller (usb1), add missing phy-supply link for USB1 phy
controller this changes fixed the power issue on usb ports.
Changes help fix usb reset warning.
