Hi everyone,
the following patch set directs to improve the scaling performance of DISPC
module which consists of two pacthes.
The first patch is based on code of Lajos Molnar <lajos@ti.com> from Android
Kernel, which updates the code with new set of coefficients to improve the
scaling performance.
The second patch is based on some very valuable suggestions by
Sebastien Fagard <s-fagard@ti.com> and directs to modify the clock
requirements for scaling to support OMAP4 and avoid clock failure issues.
I have tested these patches on OMAP2, OMAP3 AND OMAP4. To test on 2430SDP
board I have created a patch to enable the display which will follow later.
All your comments and suggestions are welcome.
Regards,
Chandrabhanu

Thanks, this looks good. Applied to DSS master branch. There was a minor
conflict with the Makefile, but I fixed that.
Btw, when doing new versions of a patch series, it would be good to have
a short history of the series in the introduction email, so that the
reviewers can easily see what's new in each version.

Thanks Tomi ! Its a good idea to including history of the series in
the introduction. I will do so in further patches to come.
