Subject: [PATCHv2 1/4] ARM: dts: meson8b: odroidc1: Add usb phy power node
Date: Fri, 16 Jul 2021 10:36:33 +0000 [thread overview]
Message-ID: <20210716103651.1455-2-linux.amoon@gmail.com> (raw)
In-Reply-To: <20210716103651.1455-1-linux.amoon@gmail.com>
Add missing usb phy power node for phy mode fix below warning.
P5V0 regulator suppy input voltage range to USB host controller.
As descriped in the C1+ schematics, GPIO GPIOAO_5 is used to
enable input power to USB ports, set it to Active Low.
