Subject: [PATCH 05/05] sh: enable deferred io LCDC on Migo-R
Date: Fri, 19 Dec 2008 15:34:50 +0900	[thread overview]
Message-ID: <20081219063450.2703.46469.sendpatchset@rx1.opensource.se> (raw)
In-Reply-To: <20081219063359.2703.85817.sendpatchset@rx1.opensource.se>

From: Magnus Damm <damm@igel.co.jp>

Enable LCDC deferred io on Migo-R using 1s delay.

As with other deferred io frame buffers user space code should
use fsync() on the frame buffer device to trigger an update.
