Subject: Stopping mmc clock between transfers
Date: Tue, 24 May 2011 14:42:32 -0400 [thread overview]
Message-ID: <BANLkTikbm_OjtwB4fhwj1Mc0HAsNPH3CVg@mail.gmail.com> (raw)
Hello,
We are using a OMAPL108 with 2.6.33 and noticed that the mmc clock
signal stays active when idle. This doesn't seem very power efficient
and we wondered if there was a reason for this. Before trying to fix
this on our side I had a few questions regarding this:
-Is this behavior the same in more recent versions?
-Was this designed to be this way?
-Would stopping the clock be a responsibility of the core (set_ios) or
the host controller (between requests)?
Regards
Marc
