[PATCH V2 0/3] OMAPDSS: DISPC: Enable predecimation for DMA and VRFB
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. In version 2 patch description has been modified include reason for maximum predecimation limit of 16. 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. In version 2 the pcd factor has been replaced lclk / pclk to support HDMI and tv output as pointed out by Ville Syrjälä. The third patch corrects the usage of dispc fclk in scaling checks by replacing it with dispc_core_clk as per suggestions of Ville Syrjälä. I have tested these patches successfully on OMAP2, OMAP3 AND OMAP4 on the mainline kernel v3.3. Horizontal and vertical predecimation worked fine but skewed images were seen on OMAP2 and OMAP3 on HDMI tv during horizontal predecimation which will be addressed in the future patches. All your comments and suggestions are welcome.
