Subject: [PATCH 3/3] OMAP3 powerdomains: make USBTLL SAR only available on ES3.1 and beyond
Date: Thu, 05 Feb 2009 20:45:28 -0700	[thread overview]
Message-ID: <20090206034525.31313.32758.stgit@localhost.localdomain> (raw)
In-Reply-To: <20090206033847.31313.45612.stgit@localhost.localdomain>

Richard Woodruff writes that chip errata prevent USBTLL SAR from working
on OMAP3 ES levels before ES3.1:

http://marc.info/?l=linux-arm-kernel&m=123319614808833&w=2

Update the OMAP3 powerdomain structures appropriately.
