The patch titled
mbxfb: Improvements and new features
has been removed from the -mm tree. Its filename was
mbxfb-improvements-and-new-features.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: mbxfb: Improvements and new features
From: Raphael Assenat <raph@xxxxxx>
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
