Input: touchsceen - convert timers to use timer_setup()

2017-10-24T17:09:33+00:00

In preparation for unconditionally passing the struct timer_list pointer to
all timer callbacks, switch to using the new timer_setup() and from_timer()
to pass the timer pointer explicitly.

Input: ad7879 - use managed devm_device_add_group

2017-09-29T23:51:07+00:00

Commit 57b8ff070f98 ("driver core: add devm_device_add_group() and
friends") has added the managed version for creating sysfs group files.

Use devm_device_add_group instead of sysfs_create_group and remove the
action that cleans the sysfs file when exiting the driver.

Input: ad7879 - do not manipulate capability bits directly

2017-03-01T17:42:45+00:00

Instead of manipulating capabilities bits of input device directly, let's
use input_set_capability() API.

Also, stop setting ABS_X/Y bits explicitly as input_set_abs_params() does
this for us.

Input: ad7879 - try parsing properties on non-DT systems

2017-03-01T17:42:44+00:00

We have switched the driver to use generic device properties API, so there
is no need to check for presence of DT node before trying parse properties.

Input: ad7879 - return plain error code from ad7879_probe()

2017-03-01T17:42:44+00:00

With the switch to devm, there is no need for ad7879_probe() to return the
touchscreen structure, we can use plain error code. This also fixes issue
introduced with devm concersion, where we returned 0 on success (which
worked OK since IS_ERR(0) would not trigger, but was not correct
regardless).

Input: ad7879 - make sure we set up drvdata

2017-03-01T17:42:43+00:00

The conversion to devm accidentally removed setting up of I2C client data
upon successful probe of the touchscreen. Let's move this setting into the
core, so we do not forger about it again.

Input: ad7879 - allow exporting AUX/VBAT/GPIO pin via device property

2017-02-23T17:21:27+00:00

Up until now only platforms using legacy platform data were able to switch
AUX/VBAT/GPIO pin in GPIO mode and use it as regular GPIO line. Let's
allow platforms using generic device properties to do the same.

Input: ad7879 - use more devm interfaces

2017-02-23T17:21:26+00:00

gpiochip_add now has a managed version, and we can remove sysfs attribute
group via devm_add_action_or_reset (at least until we have devm version of
sysfs_create_group). This allows us to get rid of ad7879_remove().
