After the discussion with Nicolas, I remember that you said that you will take the patches in your tree. I addressed Mark comments related to the last version of patches. Is there something that must be reworked in order to take the patches? On 7/13/18 7:47 PM, Radu Pirea - M19893 wrote: > Hello, > > This is the second version of driver.
