Subject: [PATCH 0/3] mmc: dw_mmc: Fix the CTO timer patch
Date: Wed, 27 Sep 2017 13:56:28 -0700	[thread overview]
Message-ID: <20170927205631.31559-1-dianders@chromium.org> (raw)

Recently we landed 03de19212ea3 ("mmc: dw_mmc: introduce timer for
broken command transfer over scheme").  I found a bunch of problems
with that patch, so this series attempts to solve some of them.

NOTE: this series has only been lighly tested so far.  I can at least
reproduce the need for the CTO timer on one of my devices and so I can
confirm that part still works.  As mentioned in the 3rd patch I also
ran the mmc_test kernel module on this and did manage to see the 3rd
patch doing something useful.


Douglas Anderson (3):
  mmc: dw_mmc: cancel the CTO timer after a voltage switch
  mmc: dw_mmc: Fix the CTO timeout calculation
  mmc: dw_mmc: Add locking to the CTO timer
