Hi everyone,
This patchset implements the interleaved transfer capability found on some AT91 SoCs.
The hardware actually support a somewhat similar mode called picture-in-picture, that allows to transfer a squared portion of a framebuffer.
That actually means that the interleaved transfer that this hardware support will need to have the same size and ICGs across all its chunks.
It has been tested on the SAMA5D36.
Let me know what you think! Maxime
