Some devices (chromebooks) present the ACPI ALS device but do not have
ability to notify when a new sample is present.
Add support for software trigger (hrtimer/sysfs-trigger) to allow
retrieving samples using iio buffers.

The first path fully adds timestamp channel, the second adds a local
variable in probe routine and the last one adds trigger support.

This patch assumes the patch "iio: set default trig->dev.parent" is
applied.

Changes since v7:
  rebase on iio git testing branch.

Gwendal Grignou (3):
  iio: acpi_als: Add timestamp channel
  iio: acpi_als: Add local variable dev in probe
  iio: acpi_als: Add trigger support

Applied to the togreg branch of iio.git and pushed out as testing for
the autobuilders to poke at it.

Thanks,
