From 00b67286e88ac2b2f4249ceeaaac3d1647525052 Mon Sep 17 00:00:00 2001 From: Huang zhibao Date: Thu, 17 Nov 2022 18:09:31 +0800 Subject: [PATCH] arm64: dts: rockchip: add RK3528 Demo board devicetree Disable u2 lpm and susphy for dwc3: The demo boards of rk3528 only support USB 2.0 OTG. This patch adds USB DWC3 property "snps,dis_u2_susphy_quirk" to avoid the USB 2.0 PHY enter suspend mode if the suspend conditions of DWC3 controller are valid. It can fixes the USB 2.0 PHY enter suspend mode unexpectedly which leads to DWC3 device enumeration fail. And let USB 2.0 PHY driver manage the PHY suspend mode. This patch also adds property "snps,usb2-lpm-disable" for DWC3 xHCI host mode. Because we found that a lot of USB Disks have USB2 HW LPM broken issue when connected to the USB DWC3 interface.
