You might want to try my for-next branch or wait for 3.8-rc1, maybe
the
DMA termination patch helps? Also enabling I2C debug messages is
probably worth it.

I've tested your git tree, with the same config as I used for the
3.7.0-rc6 release (IMX i2c build in)
It's not a 100% fix
If I do "i2cdetect -y -r 0" with 3.7.0-rc6, i2cdetect gets confused
and the kernel keeps dumping "mxs-i2c 80058000.i2c: Failed to get PIO
reg. write descriptor."
If I do the same with your git release I get the same result, but only
when i2cdetect is running. When it's finished or I terminate, the
kprint will also disappear.
So there is some improvement but not 100% yet.
