This patch adds a generic power script configuration.
When rebooting an OMAP3530 at 125 MHz, the reboot hangs.
With the generic power script, TWL4030 will be reset
when a warm reset occures. This way the OMAP3530 does not
hang on reboot.

Thanks for making this generic Matthias..
Tested-by: Robert Nelson <robertcnelson@gmail.com>
Tested on Beagle C4 (omap3530) and Beagle xM (DM3730, no regressions)
with this patch to enable it on the Beagle..

Both look OK to me. I've added Peter to cc, it's best that he queues
all the twl changes.

Peter any comments on this patch?
Are you maintaining the whole twl4030 support or just the codec driver?

The patch looks good to me as well.

Right now I'm maintaining the audio support (audio MFD, vibra, ASoC) in twl*
While I have done some cleanup in the twl-core and related drivers recently
and I'm reviewing patches sent for any *twl* driver (if I'm in the CC) I have
not declared myself as Maintainer of the twl stack.
The problem with the twl stack is that the drivers are spread around in
different subsystem so if one takes maintainer responsibility for the stack,
he/she need to have several entries in MAINTAINERS file to cover twl. I still
don't think it is a good idea to 'bloat' the MAINTAINERS file for this.
I'm happy to review patches. About a year ago we had internal discussion
regarding to twl in upstream and Tero Kristo 'volunteered' to review patches
as well.
I still think that the twl patches should be queued via the corresponding
subsystem (OMAP, MFD, Input, GPIO, PWM, etc).

It looks like the patch wasn't added to the 3.9 series. Is there any
reason for that, or was it just a misunderstanding between you two,
about who will push it to Linus?

Sorry looks like this got missed. I suggest Peter collects the twl
patches and then provides me + mfd + asoc and whoever needs the
pull requests.

This patch adds a generic power script configuration.
When rebooting an OMAP3530 at 125 MHz, the reboot hangs.
With the generic power script, TWL4030 will be reset
when a warm reset occures. This way the OMAP3530 does not
hang on reboot.
