Subject: [PATCH 4/6] omap3: Add DPLL tables for silicon rev 1 and 2
Date: Thu, 30 Dec 2010 19:19:56 +0530	[thread overview]
Message-ID: <1293716998-5154-4-git-send-email-premi@ti.com> (raw)
In-Reply-To: <1293716998-5154-1-git-send-email-premi@ti.com>

This patch adds DPLL tables for OMAP34xx ES1.0 and ES2.0.

When more than one table is added, the get_xxx_dpll_param()
was updated to use the tables corresponding to ES2.0 to
ensure that current functionality doesn't break.

In addition, the tables have been reformatted for better
readability.
