This patch adds a new trigger that can be invoked by writing
the sysfs file: trigger_now. This approach can be valuable during
automated testing or in situations, where other trigger methods
are not applicable. For example no RTC or spare GPIOs.
Last but not least we can allow user space applications to produce triggers.
IIO: TRIGGER: Apply review feedback by Greg Kroah-Hartman
Changes since v1:
Add sysfs documentation.
Change license notice.
Add module alias.
Add more Kconfig help text

There are currently two implementations of the Samsung BIOS that controls the rfkill
switch, backlight brightness / power and performance level. The samsung-laptop driver
implements the BIOS flavor with the SECLINUX signature, this patch implements talking
to the other BIOS with 'SwSmi@' signature. Both expose very similar functionality and
way of accessing the commands. The differences are mostly offsets, command identifiers
and some values.
This patch introduces a sabi_config structure that contains information on identifying
and accessing specific SABI flavors.

..and store it in dcon_priv. This renames it to 'monochrome',
which I think is much clearer. Previously, "echo 1 > output"
toggled mono mode, while "echo 0 > output" enabled color.
"Echo 1 > monochrome" makes more sense to me.

Rather than using the global i2c_client variable, create a dcon_priv
struct, store in the drvdata portion of the dev, and pass that around.
In order to access dcon struct from various callbacks, include
the reboot notifier and source switching work struct in the dcon struct.

The original code had calls to snprintf(p, 7, "wpa_ie=") but that string
is 8 characters (because snprintf() puts a NUL terminator on the end).
So instead of an '=' the what gets written to buf is a NUL terminator
followed by the rest of the string.
And actually the %02x formats are three chars as well when you include
the terminator.
