From e730d8b0a5882b66c169e1bed09774d5d365e2e0 Mon Sep 17 00:00:00 2001 From: Haavard Skinnemoen Date: Tue, 12 Aug 2008 15:08:56 -0700 Subject: atmel_lcdfb: set ypanstep to 1 and enable y-panning on AT91 Panning in the y-direction can be done by simply changing the DMA base address. This code is already in place, but FBIOPAN_DISPLAY will currently fail because ypanstep is 0. Set ypanstep to 1 to indicate that we do support y-panning and also set the necessary acceleration flags on AT91 (AVR32 already have them.)
