Hi everyone, the following patch set directs to enable predecimation for DMA and VRFB which consists of two pacthes.
The first patch is based on code written by Lajos Molnar <la...@ti.com> in Android Kernel, which updates the code with predecimation logic thereby increasing the downscaling ability of the DISPC module. The second patch is based on code written by Ville Syrjälä <ville.syrj...@nokia.com> which aims to avoid synclost errors occurring in OMAP3 due to some undocumented horizontal position and timing related limitations which I faced during testing of the previous patch. I have tested these patches successfully on OMAP2, OMAP3 AND OMAP4 on the mainline kernel v3.3-rc5. Horizontal and vertical predecimation worked fine but skewed images along with underflow errors were seen on OMAP2 and OMAP3 during horizontal predecimation which will be addressed in the future patches. All your comments and suggestions are welcome.
