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/

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
- led-max-microamp : Maximum LED supply current in microamperes. This property

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
-existing subsystems with minimal additional code. Examples are the ide-disk,
