Frankly, I don't understand why this is a series. It's a single driver
and splitting it into a series just makes it more difficult to review,
actually.

Sure, a single patch will be large, but there's no way to have a
functional driver until all patches are applied, anyway.
"

Felipe should I split this driver as suggested by Roger ?.
Now it's very big patch but it's still a single driver.
