Subject: [PATCH 3/5] video: msm: change to min/max clock calls
Date: Tue, 13 Jul 2010 13:03:09 -0700 [thread overview]
Message-ID: <1279051391-16564-3-git-send-email-dwalker@codeaurora.org> (raw)
In-Reply-To: <1279051391-16564-1-git-send-email-dwalker@codeaurora.org>
The clocks used for mddi are MIN/MAX clocks. They can't be set to
a specific clock value, only be given a min and max. We can fake
it by make the min equal the max.
This is a hack, we really need to make the min/max different and set
it in a acceptable way.
