+Freescale FlexTimer Module (FTM) Alarm

+Note:
+- The driver depends on RCPM driver

+- Need stop using RTC_HCTOSYS or use the DT aliases

+
+Required properties:
+- compatible : Should be "fsl,<chip>-ftm-alarm", the

+ "fsl,ls1012a-ftm-alarm"

+ "fsl,ls208xa-ftm-alarm"
+- reg : Specifies base physical address and size of the register sets for the

+- interrupts : Should be the FlexTimer Module interrupt.

You removed the IP Powerdown exception register in the examples, but not here.

Bindings are for h/w, not drivers...
'dt-bindings: rtc: ...' for the subject prefix.

This is Linux specific and not relevant to the binding.

Drop the aliases part. It's not going to work when this is converted
to DT schema and the comment is Linux specific.

Before there are any users of this, either drop it if it is not
variable or the correct form would be '#fsl,rcpm-wakeup-cells'.

Sorry,I can't drop the aliases part. If any user uses the alarm driver as rtc0,
the user will get wrong time from /dev/rtc0.It is very important.

I will replace 'fsl,#rcpm-wakeup-cells' with '#fsl,rcpm-wakeup-cells' in v6.

I just mean don't put it in the example. You can use it in your dts file.
