commit fae16989be77b09bab86c79233e4b511ea769cea upstream.

Commit fe6b0dfaba68 ("Input: tegra-kbc - use reset framework")
accidentally converted _deassert to _assert, so there is no code
to wake up this hardware.

The driver handles wakeup irq correctly using device_init_wakeup and
enable_irq_wake. There's no need to use IRQF_NO_SUSPEND while registering
the interrupt.

This patch removes the use of IRQF_NO_SUSPEND flag.

Though the tegra-kbc driver should/will continue to support the legacy
"nvidia,wakeup-source" property to enable keyboard as the wakeup source,
we need to add support for the new standard property "wakeup-source".

This patch adds support for "wakeup-source" property in addition to the
existing "nvidia,wakeup-source" property.

This changAdd support for EV_ABS / EV_REL events to the gpio-keys-polled driver.


The driver already allows specifying what type of events (key / rel / abs)
a button generates when pressed, but for rel / abs axis we also need to
specify which value this specific gpio represents.

One use case is digital joysticks / direction-pads which are hooked up to
gpio, in this case we've left and right buttons which we want to map to
EV_ABS, ABS_X and we want generate events for left with a value of -1 and
for right with a value of +1 (and similar for up / down and ABS_Y).

The driver depends on GOLDFISH but there isn't a build dependency
so it's a good idea to allow the driver to be built even if that
option is disabled, if the COMPILE_TEST option is enabled.

That way, the driver can be built with a config generated by make
allyesconfig and can be checked if a patch would break the build.

In the cases where the gpio chip fails to acquire the current state an
error is reported back to gpio_keys. This is currently interpreted as if
the line went high, which just confuses the developer.

This patch introduces an error print in this case and skipps the
reporting of a input event; to aid in debugging this issue.

Merge with Linux 4.3-rc3 to bring in MFD DA9062 changes to merge DA9062

If omap4_keypad_parse_dt() fails we returned the error code but we
missed releasing keypad_data.
