From d462fea9a0d95f93fa4f1623c055f4e367d997c2 Mon Sep 17 00:00:00 2001 From: Rohith Kollalsi Date: Thu, 12 Aug 2021 15:06:59 +0530 Subject: [PATCH] ARM: dts: msm: Add disable u1 quirk and u2 quirk for blair U1 and U2 are intermediate low power states. If host side and device side u1 and u2 is supported then host sends a bus reset signal when usb bus is idle which causes usb disconnect and connect. This effects many automation runs as adb will be disconencted and reconnected. Hence, disable u1, u2 on blair to solve this.
