[PATCH 0/7] ARM: ux500: More DT only clean-ups for the platform

[PATCH 0/7] ARM: ux500: More DT only clean-ups for the platform

[Lee Jones]

Hi Linus,

I was bored on the plane home, so knocked this together. This is
probably the penultimate set of clean-ups. The final one will be
the removal of MSP devices once my Audio patch-set lands.

Sorry, it's midding a 'B' - [A|D]B8500

Some people prefer something like {A,D}B500

Take your pick and fixup as you see fit.

If you're repeatedly doing pinctrl_lookup_state() in your driver,
then *this* is the problem, not that the pinctrl_lookup_state()
is not mutexed.

You should lookup your states at probe() and at runtime
only use pinctrl_select_state() to move between different
states.

Can you please refer me to the code in the upstream kernel
that is causing this.

If your code is not upstream and you're abusing the interface
as described above, the actual problem you have is that
you need to get your code upstream and properly reviewed
by the community.

Yours,
Linus Walleij

The patch summary line is slightly off.  There's nothing here to do with
ATAGs.

I'm confused.

Is this an Acked-by? Or do you want me to do something different?

Oh I see. Yes you're right, it was just what Arnd, myself and a few
others called non-DT 'cos it was easier.

Linus are you happy to fixup the subject lines of these two commits or
would you like me to re-submit?

They're not there yet, no. But this stuff is not used anymore in
Mainline hence the patch. I attempted to supply bindings for them, but
they were rejected. Would you like to have a stab at that?

We are suffering with some MMC issues presently on Snowball, this
could well be the cause.

Likewise.

NB: When you post review comments, try not to forget to <snip> all
unrelated cruft. Scrolling down for pages to find them is not optimal.

Yeah but we basically regressed the ux500 with the patch now
queued for v3.13:
commit 49c129519a7a8840767321c38d2eaf84a263529b
"ARM: ux500: Stop passing MMC's platform data for Device Tree boots"

Which deleted the passing of this non-yet-DT:ed platform
data.

Since it's a regression we need to do a fixup patch for the
v3.13 series adding it back.

Since this patch probably needs to be rewritten on top of
that I don't merge this patch as of now.

Yours,
Linus Walleij

Why would two threads come in there at the same time?

We have exactly one pinctrl* handle per device, and we
select the state on it. This is like for example the device
driver would have one thread telling it to go to "default"
state and another thread telling it to go to "idle" or "sleep"
state for example.

If we really have a device driver doing such things
for a good reason, then we need to protect it, but I
want to see that device driver first.

I am quite sure that it's safe to say that the upstream
kernel does not contain a device that will ask the hardware
to move around between different states like this from
different threads, such calls will be serialized by the
nature of sequencing in e.g. runtime PM.

I need to see the device driver and the use case so I
can understand why this would be needed.

I think the need from this arise from an abuse of the
pin controller states.

Linus Walleij
