From: Krzysztof Helt Date: Tue, 16 Oct 2007 08:28:29 +0000 (-0700) Subject: pm3fb: copyarea and partial imageblit suppor X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e7f76df9648ccd69a99fe6bc7d774dc05922f2f0;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git pm3fb: copyarea and partial imageblit suppor This patch adds accelerated copyarea and partially accelerated imageblit functions. There is also fixed one register address in the pm3fb.h file.
