[PATCH v3 0/6] mfd: twl4030-power: Enable off-idle configuration when booted with device tree

[Tony Lindgren]

Hi Lee,

Here are these patches for you again as you requested.
I left out the last patch in the series containing the
related .dts changes to enable these features as
that I can apply separately.

Regards,

Tony

[PATCH 1/6] mfd: twl4030-power: Fix hang on reboot if sleep configuration was loaded earlier

[Tony Lindgren]

Looks like we can still hit the issue of wrong load order of
twl4030 configuration. If we have a sleep configuration loaded,
and do a warm reset, the device can hang while initializing the
wakeup12 sequence. We do have a warning message about wrong order
of twl4030 configuration, but in this case it does not help as
the sleep configuration was loaded during the previous boot and
the state of twl4030 is maintained throughout the warm reset.

Fix the issue by clearing any existing sleep configuration
before we load the warm reset configuration.

[PATCH 2/6] mfd: twl4030-power: Fix some defines for SW_EVENTS

[Tony Lindgren]

We have these bits partially defined in two different
places, so let's fix them up and add defines for the
missing bits. These bits are the same for P1_SW_EVENTS,
P2_SW_EVENTS and P3_SW_EVENTS.

[PATCH 3/6] mfd: twl4030-power: Add generic reset configuration

[Tony Lindgren]

The twl4030 PMIC needs to be configured properly for things like
warm reset and deeper idle states so the PMIC manages the regulators
properly based on the hardware triggers from the SoC. Earlier
we have configured twl4030 using platform data, but we want to
do it for device tree based booting also.

In some cases configuring twl4030 is needed for things to work.
For example, when rebooting an OMAP3530 at 125 MHz, it hangs.
With this patch, TWL4030 will be reset when a warm reset occures,
and OMAP3530 does not hang on reboot.

Let's add device tree support and configure things for warm reset
as the default when compatible = "ti,twl4030-power". More
complicated configurations can be added to the driver based on
other compatible flags.

Note we now also make the pdata const like it should be.
This allows use it for match->data with the device tree
related functions.

Based on earlier patch by Matthias Brugger <matthias.bgg@gmail.com>
and Lesly A M <leslyam@ti.com>.

Do we really need remap active?
As far as I can see it's not used anywhere.

[PATCH 4/6] mfd: twl4030-power: Add recommended idle configuration

[Tony Lindgren]

These settings are based on the "Recommended Sleep Sequences for
the Zoom Platform".

The settings assume most of the regulators are under control of
Linux, and twl4030 only cuts off VDD1 and VDD2 during off-idle as
Linux cannot do it.

For any board specific changes to these, let's patch them in as
changes to the generic data in the follow-up patches. This keeps
the board specific changes small.

Note that this does not consider the twl5030 errata 27 and 28.
That can be added later on after it has been tested. For more
information about errata 27 and 28.

[PATCH 5/6] mfd: twl4030-power: Add support for board specific configuration

[Tony Lindgren]

With the recommended twl4030 configuration added, we can now add
board specific changes as modifications to the recommended
configuration.

Note that the data is private to this driver, and the data must
always have a NULL resource in the sentinel.

[PATCH 6/6] mfd: twl4030-power: Add a configuration to turn off oscillator during off-idle

[Tony Lindgren]

Some oscillators can be turned off during off-idle saving few
a little bit power at the cost of the oscillator start up
latency.

If you board can do this, you can now enable it by using the
ti,twl4030-power-idle-osc-off compatible flag.

Thanks a lot, this will make it easier for me to chase down potential
PM related regressions ;) I'm merging this for testing only into the
linux-omap master branch, no need for me to include it into any
of my upstream heading branches.

Regards,

Tony

Lee, I'm not seeing this in linux next, did you maybe forget to merge
it into the MFD tree?

I didn't forget, but I didn't do it either. :)

I have re-merged all of the IBs this morning, so should be in -next
by tomorrow.

Oh crap, I see what's happened and it's completely my fault.

If you read the final merge commit carefully:

28fee3f: ("Merge branches 'ib-from-asoc-3.16', 'ib-from-pm-3.16',
'ib-from-regulator-3.16', 'ib-mfd-gpio-3.16' and
'ib-mfd-mmc-memstick-3.16', tags 'ib-mfd-extcon-3.16',
'ib-mfd-omap-3.16' and 'ib-mfd-regulator-3.16' into
ibs-for-mfd-merged")

I appear to have a _branch_ AND a _tag_ called ib-mfd-omap-3.16 and it
looks like Git has taken the tag as a preference. heads/ib-mfd-omap-3.16
is actually at tag/ib-mfd-omap-3.16-1 (notice the appended '-1'),
which contains your most recent patches.  Since I created the MFD-OMAP
shared branch I have changed the naming convention to avoid this sort
of ambiguity.  I'll send a second MFD pull-request to Linus today.

Sorry Tony.

Pull-request sent.  Hopefully it's sorted now.

If there are any more issues I'll sort them out as they appear, but I
may be a little slower than usual as I'm currently on holiday in Spain.
