Marc Zyngier afefc32662 gpio: Update TODO to mention immutable irq_chip structures
5 drivers are converted, a few hundred to go. Definitely worth of
a TODO entry, in the hope that someone will notice it and do
a bulk update.

Andy Shevchenko 5f7582aa2d gpio: intel-mid: Remove driver for deprecated platform
Intel Moorestown and Medfield are quite old Intel Atom based
32-bit platforms, which were in limited use in some Android phones,
tablets and consumer electronics more than eight years ago.

There are no bugs or problems ever reported outside from Intel
for breaking any of that platforms for years. It seems no real
users exists who run more or less fresh kernel on it. The commit
05f4434bc1 ("ASoC: Intel: remove mfld_machine") also in align
with this theory.

Due to above and to reduce a burden of supporting outdated drivers
we remove the support of outdated platforms completely.

Moreover this code duplicates gpio-pxa since the IP has been derived
from XScale implementation. If anybody wants to resurrect this
it has to be part of gpio-pxa.c.

dangerous sysfs ABI for hacking and tinkering came up
on the list.

Linus Walleij f1f37abbe6 gpio: Retire the explicit gpio irqchip code
Now that all gpiolib irqchip users have been over to use
the irqchip template, we can finally retire the old code
path and leave just one way in to the irqchip: set up the
template when registering the gpio_chip. For a while
we had two code paths for this which was a bit confusing.

This brings this work to a conclusion, there is now one
way of doing this.

The word 'descriptor' is misspelled throughout the tree.

Fix it up accordingly:
    decriptors -> descriptors

Andy Shevchenko 85a94ff8fb gpio: Extend TODO to cover code duplication avoidance
It appears at least two drivers has a lot of duplication code in
GPIO subsystem. To avoid adding more and get rid of existing duplication
extend TODO.

Linus Walleij 2646b90de5 gpio: Add global TODO file for GPIO
With a new subsystem co-maintainer on board it is good to draw
up the ongoing changes and future plans for the subsystem, i.e.
what is in my head and being worked on long term.

What better way is there than simply adding a TODO right in the
code and send it out to the mailing list.
