[PATCH 0/3] video: clps711x: New CLPS711X FB driver

This series adds a new framebuffer driver for Cirrus Logic CLPS711X
CPUs. Since all code rewritten from scratch, patch is designed as a
replacement of the old (not updated for a long time) for a new one.
The second part of the patch affects changes for the ARM CLPS711X
core subsystem, so ACK from the ARM maintainers would be useful.
Patch originally designed for apply to the video subsystem, but I
have no prejudice it and if it will be applied to the arm-soc branch,
this will also be good.

Why was it rewritten from scratch? It's almost always better to improve
the old one, than write a new, replacing one.

Hello.

Most of the code has been rewritten. It will be very difficult to see the changes,
if it is presented as a patch for the old driver.

Well, now it's impossible to see the changes, except opening both files
and going through line by line. You don't even list any new features in
the description, or give any reason why a new driver is required.

And of course one huge patch changing the old driver to the new form is
bad also.

The proper way would be to gradually change the old driver with a patch
series. Then it's possible to review the patches and see what is
actually changed.
