From 4ed824d9aead77a6a4eb1e89c3b3d270ba386fad Mon Sep 17 00:00:00 2001 From: Sudhakar Rajashekhara Date: Tue, 22 Sep 2009 16:47:06 -0700 Subject: davinci: fb: Frame Buffer driver for TI DA8xx/OMAP-L1xx Add LCD controller (LCDC) driver for TI's DA8xx/OMAP-L1xx architecture. LCDC specifications can be found at http://www.ti.com/litv/pdf/sprufm0a. LCDC on DA8xx consists of two independent controllers, the Raster Controller and the LCD Interface Display Driver (LIDD) controller. LIDD further supports character and graphic displays. This patch adds support for the graphic display (Sharp LQ035Q3DG01) found on the DA830 based EVM. The EVM details can be found at: http://support.spectrumdigital.com/boards/dskda830/revc/.
