Hi Guennadi,

I wanted to test this driver on my board. However it does not work for
me. I have pulled the version that is on async-tx tree so it should be
up to date and it compiles fine.

Unfortunately the fb driver cannot register because it cannot request a
dma channel (there are no dma registered in dmaengive, the list is
empty). This is because the ipu-core platform_driver is never
registered. This is supposed to be done thanks to the
subsys_initcall(ipu_init) as we can see it in the patch (which is then
going to be linked with the ipu-core device that is registered witth the
other mx3 device). I never happen to see one of the ipu_probe messages
(even for failure) with dynamic_printk enabled.

You need the patch 4/4 - platform bindings, which is not in that queue and 
will only be merged in the next kernel version. You can so far pick it up 
here:

Thanks
