The first patch is based on code of Lajos Molnar 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 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.
