Subject: [PATCH v1 1/9] scsi: ufs: add support to allow non standard behaviours (quirks)
Date: Fri, 6 Jul 2018 18:00:28 +0530 [thread overview]
Message-ID: <36c4fc866db111df0de7c30839a40727aaa3a98b.1530880006.git.asutoshd@codeaurora.org> (raw)

In-Reply-To: <cover.1530880006.git.asutoshd@codeaurora.org>
From: Subhash Jadavani <subhashj@codeaurora.org>
Some implementation of UFS host controller HW might have some
non-standard behaviours (quirks) when compared to behaviour
specified by UFSHCI specification. This patch adds a quirk
for broken hibernate support.
