Input: da9063_onkey - avoid explicitly setting input's parent

devm_input_allocate_device() already sets parent of the new input
device, there's no need to set it up explicitly.

There is nothing OF-specific in the driver, so switch from OF properties

Input: da9063 - drop redundant prints in probe()

The memory allocation core code already prints error message in case of
OOM. So, drop additional print messages for OOM cases.

While at it, input_register_device() is already printing error messages on
failure. Drop the redundant print.

Input: da9063 - simplify obtaining OF match data

Simplify probe() by replacing of_match_node() for retrieving match data by
device_get_match_data().

Some minor cleanups:
* Remove the trailing comma in the terminator entry for the OF
table making code robust against (theoretical) misrebases or other
similar things where the new entry goes _after_ the termination without
the compiler noticing.
* Move OF table near to the user.
* Arrange variables in reverse xmas tree order in probe().

Input: da9063 - fix capability and drop KEY_SLEEP

Since commit f889beaaab1c ("Input: da9063 - report KEY_POWER instead of
KEY_SLEEP during power key-press") KEY_SLEEP isn't supported anymore. This
caused input device to not generate any events if "dlg,disable-key-power"
is set.

Fix this by unconditionally setting KEY_POWER capability, and not
declaring KEY_SLEEP.

Input: remove dev_err() usage after platform_get_irq()

We don't need dev_err() messages when platform_get_irq() fails now that
platform_get_irq() prints an error message itself when something goes
wrong. Let's remove these prints with a simple semantic patch.

// <smpl>
@@
expression ret;
struct platform_device *E;
@@

ret =
(
platform_get_irq(E, ...)
|
platform_get_irq_byname(E, ...)
);

if ( \( ret < 0 \| ret <= 0 \) )
{
(
-if (ret != -EPROBE_DEFER)
-{ ...
-dev_err(...);
-... }
|
...
-dev_err(...);
)
...
}
// </smpl>

While we're here, remove braces on if statements that only have one
statement (manually).

Input: da9063 - fix module autoload when registered via OF

If the driver is built as a module, autoload won't work because the module

device with the corresponding module.

Export the module alias information using the MODULE_DEVICE_TABLE() macro.

Input: da9063 - report KEY_POWER instead of KEY_SLEEP during power key-press

Stop reporting KEY_SLEEP for a short key-press and report KEY_POWER instead
This change applies to both DA9063 and DA9062 ONKEY drivers.

A previous application used for testing by the developer required a
KEY_SLEEP and KEY_POWER input_report_key event to distinguish between a
short and long key-press of the power key. This is not the general
convention and the typical solution is for KEY_POWER to be used in both
cases: suspend and S/W power off.

Input: add DA9062 OnKey capability to DA9063 OnKey driver

Add DA9062 OnKey support into the existing DA9063 OnKey driver component by
using generic access tables for common register and bit mask definitions.

The following change will add generic register and bit mask support to the
DA9063 OnKey.

The following alterations have been made to the DA9063 OnKey:

- Addition of a da906x_chip_config structure to hold all
generic registers and bitmasks for this type of OnKey component.
- Addition of an struct of_device_id table for DA9063 and DA9062
defaults
- Refactoring functions to use struct da9063_onkey accesses to generic
registers/masks instead of using defines from registers.h
- Re-work of da9063_onkey_probe() to use of_match_node() and
dev_get_regmap() to provide initialisation of generic registers and
masks and access to regmap
