Changes in v5:
   - Keep documentation for the old 'ide-disk' device tree
     binding, but mark as deprecated and refer to the new
     trigger 'disk-activity'.

Changes in v4:
   - Keep the 'ide-disk' trigger and add a second one
     for 'disk-activity'.

Changes in v3:
   - Port to kernel 4.x
   - Split into platform independent and dependent parts.

v2: https://patchwork.ozlabs.org/patch/117485/
v1: http://dev.gentoo.org/~josejx/ata.patch

I'd like to reorganize this change.

I think that the two affected properties should be placed next to
each other. I'd also remove the remark about ide-disk at disk-activity,
since we're leaving ide-disk, with added reference to disk-activity.

How about following:

+     "disk-activity" - LED indicates disk activity
-     "ide-disk" - LED indicates disk activity
+     "ide-disk" - LED indicates IDE disk activity (deprecated),
                   in new implementations use "disk-activity"

       "timer" - LED flashes at a fixed, configurable rate

  The class also introduces the optional concept of an LED trigger. A trigger
  is a kernel based source of led events. Triggers can either be simple or
  complex. A simple trigger isn't configurable and is designed to slot into
