Move it from exynos5250-cros-common.dtsi to exynos5250-snow.dts.
Spring does not need it, it uses an s5m8767 instead.

Hi Andreas,

I think this should be reviewed by chrome guys.


Doug, can you have a look this series for exynos5250-chromebook?
I'm not sure exynos5250-cros-common is still useful for exynos5250-spring...

Sorry, I've been on vacation and am now playing catchup.

Right.  The current suggestion is to rework to just duplicate things
and don't use exynos5250-cros-common.  I would structure the series
as:

1. Fold the current exynos5250-cros-common directly into the snow
device tree file.

2. If desired, cleanup the snow device tree file.

3. Create the spring device tree file based on snow.  There will be
duplication, but so be it.  Please try to minimize diffs between the
snow ad spring device tree files.

4. If possible, identify "fragments" like "cros-ec-keyboard.dtsi" and
factor them out of both spring and snow device tree files.


You could certainly reorder some of the above steps if you wish (you
could split out fragments before creating the spring device tree, for
instance).


Please make sure to CC Javier (now on CC) since he's helping with
Chromebook upstreaming and he may have a lower latency in responding
than I do.

Oh, it actually looks like your patch series ends up there, but the
first patch confused me.  Why move just the maxim PMIC first?  Move
everything at once and be done with the common file, then do
cleanup...

NP, guess you just started reading in the middle. ;)

Review of the movements surely is easier this way, and it did not yet
seem a done deal that we would drop -cros-common. The merge patch nicely
shows which common parts need to be copied into spring.

If everyone agrees that we want to proceed that way, we can easily
squash patches 1+2. Separating is always harder.

Cheers,

Yeah, I had this on my list to look at but ended up looking at this
one first due to Kukjin's response.

That's fine.  I can review it this way now that I realize what's going on.

Personally I would have squashed patches 1-3, but I don't have a
problem with it being broken up and it does mean that the mondo patch
is smaller, so...

Reviewed-by: Doug Anderson <dianders@chromium.org>

Kukjin could apply this now if he wanted to avoid future conflicts.
