[PATCH 0/2] OMAPDSS: DISPC: Peformance improvement of DISPC Scaling

[Chandrabhanu Mahapatra]

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
