input: matrix-keymap: Add function to read the new DT binding

2013-04-05T09:20:13+00:00

We now have a binding which adds two parameters to the matrix keypad DT
node. This is separate from the GPIO-driven matrix keypad binding, and
unfortunately incompatible, since that uses row-gpios/col-gpios for the
row and column counts.

So the easiest option here is to provide a function for non-GPIO drivers
to use to decode the binding.

Note: We could in fact create an entirely separate structure to hold
these two fields, but it does not seem worth it, yet. If we have more
parameters then we can add this, and then refactor each driver to hold
such a structure.

Drivers: misc: remove __dev* attributes.

2013-01-03T23:57:16+00:00

CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

Input: tca8418-keypad - switch to using managed resources

2012-11-29T17:30:49+00:00

Let's switch to using devm_*() interfaces to manage our resources,
thus will simplify error unwinding a bit.

Input: tca8418_keypad - increase severity of failures in probe()

2012-11-29T17:30:36+00:00

Failures to build a keymap, request an IRQ, or register input device are
fatal for the driver, therefore the messages should have "error" severity
instead of "debug".

Input: tca8418_keypad - move device ID tables closer to where they are used

2012-11-29T17:30:22+00:00

This matches structure of most other input drivers.

Input: tca8418_keypad - use dev_get_platdata() to retrieve platform data

2012-11-29T17:30:03+00:00

We need to use proper accessor functions instead of directly poking into
various structures.

Input: tca8418_keypad - use a temporary variable for parent device

2012-11-29T17:29:17+00:00

Use a temporary variable for our parent device (coming from I2C client
structure); we'll be also using it during conversion to managed resources.

CONFIG_HOTPLUG is going away as an option so __devexit is no
