omapdrm VRFB rotation

[Ivaylo Dimitrov <ivo.g.dimitrov.75@xxxxxxxxx>]

Hi,

Currently omapdrm supports TILER rotation only, which excludes omap3 and 
earlier SoCs. I have the hardware (N900/N950), time and will to 
implement VRFB rotation support in omapdrm driver, however, I'll 
appreciate some hints. Or, if there is already something ready, please 
point me to it so I can take it from where it is.

Besides partially reverting 517a8a9564c0dea98e6d4e2c7f0fe4cbb9b8c9ba and 
copying VRFB code from omapfb, is there anything else I shall take in 
consideration? Or, VRFB driver should not be a part of omapdrm, but a 
standalone one?

Regards,
Ivo
