Subject: OMAP3530 with no TWL4030 power controller
Date: Mon, 06 Feb 2012 10:44:23 -0700 [thread overview]
Message-ID: <4F301177.4020008@mlbassoc.com> (raw)
I have an OMAP3530 (DM3730) board which uses a very simple
power controller (TPS65910A1). This controller does not
support many of the power supplies, etc, that are common
on the TWL4030 and similar devices.
I'm using Linux 3.0. How can I remove the reliance on the
TWL devices? Simply disabling PM in my configuration isn't
enough - that generates a bunch of undefined references.
Also, there are many places where power supply stuff is
accessed, outside of PM, in particular DSS2 which has a
terrible time. Here's what I get when I disabled PM and
REGULATOR support:

Any ideas? I'd like to keep my changes to the kernel to
a minimum,
