From 657bf0bd068b2dc5244d553be66daac0a9e745d1 Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Mon, 7 Dec 2009 14:26:05 +0000 Subject: sh: LCDC start_transfer() for the KFR2R09 board This patch adds a ->start_transfer() callback to the KFR2R09 lcd handling code. The callback is used to notify the lcd controller that a new frame of data is about to be transferred. The callback is only used in combination with deferred io, but the code has been tested both with and without deferred io enabled. Without this patch the display data on the KFR2R09 lcd panel becomes corrupted over time.
