From 43aad09c792894727d8f6914534f43df23079926 Mon Sep 17 00:00:00 2001 From: Diego Rondini Date: Mon, 15 Jun 2020 15:02:23 +0200 Subject: ARM: dts: orange-pi-zero-plus2: enable USB OTG port 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.
