Subject: [PATCH 1/2] ARM: dts: orange-pi-zero-plus2: enable USB OTG port
Date: Thu, 28 May 2020 22:47:11 +0200	[thread overview]
Message-ID: <20200528204712.552964-1-diego.rondini@kynetics.com> (raw)

Enable support for USB OTG port on Orange Pi Zero Plus 2 (both H3 and H5
variants). As, according to the board schematics, the USB OTG port cannot
provide power to external devices, we set dr_mode to peripheral.
