PCM-038 module have three triple LEDs connected to PMIC which
can be used for diagnostic purposes. This patch adds support
for these LEDs for PCM-038 SOM and adds basic LED-triggers for
these LEDs for PCM-970 RDK, the remaining LEDs are available
for use from userspace.

I do not see this trigger and above "nand-disk" in
Documentation/devicetree/bindings/leds/common.txt.
So they're just missing from bindings doc and kernel actually supports
them?

I can only see led-control mentioned in
Documentation/devicetree/bindings/mfd/mc13xxx.txt as below.

- leds : Contain the led nodes and initial register values in property
  "led-control".

But I failed to see where this property is actually defined.

Yes, seems this is undocumented yet.
Defined in drivers/mtd/nand/nand_base.c: nand_base_init().
Present in the mainline kernel.

Not quite understand the question. Please rephrase.

The documentation of property "led-control" isn't so clear to me.  But
anyway it's not a problem of this patch.  Patch applied.
