dd0fa81143 gpio: Add TODO item for debugfs interface 
The idea to create a debugfs to replace the aging and
dangerous sysfs ABI for hacking and tinkering came up
on the list.

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.

3abda79aa1 drivers: gpio: Fix trivial spelling 
The word 'descriptor' is misspelled throughout the tree.

Fix it up accordingly:
    decriptors -> descriptors

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.

9708289013 gpio: Update TODO 
Drop the completed item: hierarchical irqchip helpers. Add
motivation for gpio descriptor refactoring. Extend the list of
stuff to do. Minor fixups.

9a82ee69ee gpio: Add GPIOLIB_IRQCHIP cleanup to TODO 
We now have two APIs for registering GPIOLIB_IRQCHIP, this is not
working and creating confusion. Add a TODO item to fix it up.

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.
