From 14340586148e7c88d7b1b752876f5b5227b200b9 Mon Sep 17 00:00:00 2001 From: Nicolas Ferre Date: Thu, 10 May 2007 22:23:26 -0700 Subject: atmel_lcdfb: AT91/AT32 LCD Controller framebuffer driver Adds a framebuffer driver to ATMEL AT91SAM9x and AT32 aka AVR32 platforms. Those chips share quite the same IP and this code is suitable for both architectures.
