Subject: [PATCH 16/19] ARM: OMAP4 clock domain: Add check for avoiding dependency related update.
Date: Mon, 15 Feb 2010 18:25:00 -0700	[thread overview]
Message-ID: <20100216012459.1101.19902.stgit@localhost.localdomain> (raw)
In-Reply-To: <20100216011942.1101.14348.stgit@localhost.localdomain>

From: Abhijit Pagare <abhijitpagare@ti.com>

A check is added for avoiding the sleep/wakeup dependency updates
for OMAP4 as the structures for the dependencies are currently absent.
