From b8993bd786c1681ce0aa65b7a04159bf712c1e21 Mon Sep 17 00:00:00 2001 From: Krishna Kurapati Date: Wed, 18 Dec 2024 20:12:57 +0800 Subject: [PATCH] arm64: dts: qcom: qcs615-ride: Enable secondary USB controller on QCS615 Ride Enable secondary USB controller on QCS615 Ride platform. The secondary USB controller is made "host", as it is a Type-A port. Secondary USB controller of QCS615 Ride has Type-A port exposed for connecting peripheral. The VBUS to the peripheral is provided by TPS2549IRTERQ1 regulator connected to the port. The regulator has an enable pin controlled by PM8150. Model it as fixed regulator and keep it Always-On at boot, since the regulator is GPIO controlled regulator.
