Subject: [PATCH v7 1/5] ARM: OMAP: gpmc: don't create devices from initcall on DT
Date: Wed,  5 Dec 2012 20:09:27 +0100	[thread overview]
Message-ID: <1354734571-10774-2-git-send-email-zonque@gmail.com> (raw)
In-Reply-To: <1354734571-10774-1-git-send-email-zonque@gmail.com>

On DT driven boards, the gpmc node will match the driver. Hence, there's
no need to do that unconditionally from the initcall.
