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.
