From 8163743e23035dd2e2ab531878517137033d62bf Mon Sep 17 00:00:00 2001 From: Yaniv Gardi Date: Sun, 17 May 2015 18:55:02 +0300 Subject: [PATCH] scsi: ufs-qcom: enable quirk to fix gear change to HS With the G3 UFS devices, changing gear into HS is failing in UFS host controllers of version 0x2. The quirk solves the problem of changing gear into HS by enabling the attribute that specifies whether or not the inbound Link supports unterminated line in HS mode.
