Subject: [PATCH] mmc: tegra: don't enable UHS modes on Tegra210
Date: Wed, 30 Dec 2015 16:49:09 +0100 [thread overview]
Message-ID: <1451490549-21430-1-git-send-email-dev@lynxeye.de> (raw)
Tegra210 needs a different tuning sequence than Tegra30+. Disable
UHS modes until support for this is properly added.

Ulf,
this is a follow on patch to my Tegra UHS-I series. After reading the
Tegra210 TRM I realized that the currently implemented tuning sequence will
only work on Tegra30..Tegra124. If you don't keep your tree stable you
might want to squash this into [PATCH v2 4/5] mmc: tegra: enable UHS-I modes,
otherwise please pick this up as a fix on top.
