From b642d4825441bf30c72b72deb739bd2d5f53af08 Mon Sep 17 00:00:00 2001 From: Ondrej Jirman Date: Sat, 22 Feb 2020 23:31:53 +0100 Subject: ARM: dts: sun8i-a83t-tbs-a711: Fix USB OTG mode detection USB-ID signal has a pullup on the schematic, but in reality it's not pulled up, so add a GPIO pullup. And we also need a usb0_vbus_power-supply for VBUS detection. This fixes OTG mode detection and charging issues on TBS A711 tablet. The issues came from ID pin reading 0, causing host mode to be enabled, when it should not be, leading to DRVVBUS being enabled, which disabled the charger.
