mbxfb: Improvements and new features
This contains the following changes: * Overlay surface alpha is configured separately from the overlay. This prevents display glitches (configure and fill the overlay first, set alpha to a visible value next) * Added an ioctl for configuring transparency of the Overlay and graphics planes. Blend mode, colorkey mode and global alpha mode are supported. * Added an ioctl for setting the plane order. The overlay plance can be placed over or under the graphics plane. * Added an ioctl for setting and reading chip registers, with mask. * Updated copyright for 2007 [adaplas] * Coding style changes Signed-off-by: Raphael Assenat <raph@8d.com> Signed-off-by: Antonino Daplas <adaplas@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
