Previous version has A64-Relic board, which has some xclk issue on
sensor side wrt 1080p. I have tried 300MHz on the same hardware, it's
failing to capture on 30fps and so I tried 600MHz(which is default) on
the same configuration but it encounter memory corruption.
So, for checking whether there is an issue with hardware on A64-Relic
I moved with BPI-M64 dev board. which is working 1080p with 300MHz, ie
reason I have not included A64-Relic on this version and included
BPI-M64. We processed A64-Relic to hardware team to figure out the
clock and once ie fixed I'm planning to send DTS patch for that.
This is overall summary, hope you understand.
