Subject: [PATCH 5/8] OMAP2PLUS:GPIO:Add OMAP2PLUS specific gpio support
Date: Wed, 31 Mar 2010 17:53:56 +0530 [thread overview]
Message-ID: <1270038239-1090-6-git-send-email-charu@ti.com> (raw)
In-Reply-To: <1270038239-1090-5-git-send-email-charu@ti.com>
This patch adds support for handling code common to OMAP2PLUS
architecture.
OMAP2PLUS gpio is one of the early platform devices and this patch
adds support to implement the initialization of OMAP2PLUS architecture
GPIO as early platform device.
