Subject: [PATCH 2/2] OMAP3 powerdomains: make USBTLL SAR only available on ES3.1 and beyond
Date: Thu, 29 Jan 2009 02:12:06 -0700 [thread overview]
Message-ID: <20090129091205.24256.48968.stgit@localhost.localdomain> (raw)
In-Reply-To: <20090129090821.24256.46439.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.
