Curious to know,
How do you test this? Do you have any OMAP2/3 or AM335x board?
Does this driver still works?
Thanks,

Hello Vaibhav,
Unfortunately I can't test it.

Thats what I expected.
I am doubtful that anyone still uses this driver.
With DRM framework support, I see very little use of this driver.
Also there are some hacks regarding buffer management, that need to be
fixed if at all we want to support it.
I would really want to slowly kill this driver, if no one uses it.
Thanks,
Vaibhav
