Ipu upscaling crops frames higher then 1024 pixels

[andreapicaro]

Hello, on a legacy imx6 device running kernel 3.0.35 we play videos using mfw_isink plugin. 

When upscaling video, it works perfectly for output horizontal width (or height) up to 1024, but the video is cropped

when scaling behiond 1024 pixels. I know ipu has limitation to 1024x1024 and that higher resolution tasks are handled by striping, is there a bug in the striping engine? Is there any patch or workaround available for it?

Thank you

The IC size for imx6 is limited to 1024x1024,if mor than this, pls refer to the linux/drivers/mxc/ipu3/ipu_device.c focus on the "create_split_task" function.
