Hi community,
I have a question about i.MX6Q IPU.
Please see Figure 37-22 in IMX6DQRM Rev.1.
According to this figure, SMFC has 4 DMA channels.
And SMFC seems that it can use multiple channels to transfer data input from MIPI-CSI.
Then, how about in the case input from parallel camera?
Can SMFC use only one DMA channel to transfer if data is input from a parallel camera?
Or can it use multiple DMA channels?
Best Regards,
Satoshi Shimoda

Hi Satoshi,
you are right, from a parallel camera SMFC can use
only one DMA channel. "DI (data identifier)" concept is used
only for MIPI interface, this is described in sect.37.4.3.2.2
