[meta-freescale] Any hope of vblank-synchronized rendering (from vivante) on i.MX6 soon?

[Carlos Rafael Giani]

Perhaps there is still time left to notify Freescale how critical this 
feature is for several people. Imagine tearing on huge displays for 
example ... this can easily become a showstopper. Freescale should 
consider this one of the most critical features to introduce in 3.10.31 GA.
