Subject: [RFC PATCH 2/2] ARM: shmobile: sh7372: Change VPU UIO to uio_dmem_genirq
Date: Wed, 12 Sep 2012 14:29:45 +0900 [thread overview]
Message-ID: <1347427785-9767-3-git-send-email-dhobsong@igel.co.jp> (raw)
In-Reply-To: <1347427785-9767-1-git-send-email-dhobsong@igel.co.jp>
This allows the VPU memory to be allocated dynamically only when it
is needed.
