91da7032d8 pinctrl: at91: fix deferred probing support 
AT91 pinctrl deferred probing support is broken if the GPIO devices
haven't probed first and set gpio_banks to non-zero. The later condition
that only some GPIO devices haven't probed can't actually happen as
either all the GPIO devices have probed first or none of them have. Plus
the pinctrl driver has already returned -EINVAL, so it's not on the
deferred list to retry probing.

Fix this by consolidating the checking that all GPIO devices are probed.

6c488fbb1d dt-bindings: pinctrl: mediatek: Fix child node name patterns 
The child node name patterns in Mediatek pinctrl bindings don't match
reality. I don't know where '-[0-9]+$' came from, but I don't see any nodes
with a matching pattern. Also, patterns such as 'pins' or 'mux' are
ambiguous because any prefix or suffix is allowed. If that's desired, it
should be explicit.

a3a7482a0d pinctrl: mxs: avoid defines prefixed with CONFIG 
Defines prefixed with "CONFIG" should be limited to proper Kconfig options,
that are introduced in a Kconfig file.

Here, expressions to convert pin configurations to booleans for pull-up,
voltage and mA are macro definitions that begin with "CONFIG".

To avoid defines prefixed with "CONFIG", rename these defines to begin with
"PIN_CONFIG" instead.

No functional change.

292a089d78 treewide: Convert del_timer*() to timer_shutdown*() 
Due to several bugs caused by timers being re-armed after they are
shutdown and just before they are freed, a new state of timers was added
called "shutdown".  After a timer is set to this state, then it can no
longer be re-armed.

The following script was run to find all the trivial locations where
del_timer() or del_timer_sync() is called in the same function that the
object holding the timer is freed.  It also ignores any locations where
the timer->function is modified between the del_timer*() and the free(),
as that is not considered a "trivial" case.

This was created by using a coccinelle script and the following
commands:

    $ cat timer.cocci
    @@
    expression ptr, slab;
    identifier timer, rfield;
    @@
    (
    -       del_timer(&ptr->timer);
    +       timer_shutdown(&ptr->timer);
    |
    -       del_timer_sync(&ptr->timer);
    +       timer_shutdown_sync(&ptr->timer);
    )
      ... when strict
          when != ptr->timer
    (
            kfree_rcu(ptr, rfield);
    |
            kmem_cache_free(slab, ptr);
    |
            kfree(ptr);
    )

    $ patch -p1 < /tmp/t.patch
