And also send the series again with I2C: Zynq: Support for 0-length register address patch as v3 i guess, [you missed v2 patch version name]
Will update the status on testing these on zynq boards.
Jagan,
I am resending as you suggest -- except I used "v2", because it seems that Heiko made the previous versions of "[PATCH] I2C:Zynq: Adapt this driver to the new model" disappear from the list. Therefore the "v1" was this: "[PATCH] I2C: Zynq: Support for 0-length register address".
However, none of that really matters much, because all of the above has been collected into the series I'm (re)sending now.
