From caa5680dc05a20c6e4419c6d4c2f863ec85f43aa Mon Sep 17 00:00:00 2001 From: Thinh Nguyen Date: Thu, 25 Apr 2019 13:55:23 -0700 Subject: [PATCH] usb: dwc3: Fix default lpm_nyet_threshold value commit 8d791929b2fbdf7734c1596d808e55cb457f4562 upstream. The max possible value for DCTL.LPM_NYET_THRES is 15 and not 255. Change the default value to 15.
