From 3d16bb640f95daffce285285f8c8355e5d2ea529 Mon Sep 17 00:00:00 2001 From: William Wu Date: Wed, 13 Apr 2022 14:47:06 +0800 Subject: [PATCH] ARM: dts: rockchip: rv1106: disable usb2 gadget lpm The Rockchip DWC3 controllers are LPM capable, but we find that the UVC function compatibility issue on some Windows PCs if enable LPM capable. And refer to the Logitech USB Cameras, they're usually disable LPM capable. Considering that the benefit form LPM capable is insignificant on RV1106 platforms with USB Gadget funcitons (UVC & UAC...), so we disable the LPM capable by default.
