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

[Prabhu S]

i.MX6 X11 EGL is single buffered and there is no support for VSYNC. The
tearing with X11 is a known issue. We did investigate to fix this, but the
solution becomes too hacky and cannot be used in production systems.

We are adding VSYNC support in Wayland. eglSwapInterval will be supported
for FBDEV and Wayland backends in the upcoming release(in january). So
Ozone-wayland can take advantage of this.
