Hi Alexandre Belloni,

Is it ok, if I send isl1208 driver enhancement patches patch#5 to patch#10,
as it has no dependencies?

Patch#11 will send later based on the discussion [1]

Cheers,
Biju

I still don't know why you say this and changed the example to be as
simple as possible.

Did you test it and does it not work with the actual driver?  I looked
at the code for parsing OF interrupts and it does not look like
anything has changed to make it not work.  Nor do I see anything
incorrect in the original example.  Can you explain what you think is
wrong with the original example?

There is nothing wrong with example. The only reason is there is no dts in mainline
matching with example.

If I am correct, example should match with reality. If it is not the case, I am happy to
update the example.

I have seen people(including me) sending patches to update example with reality.

Note:
Can you please confirm rtctest[1] is passing with interrupts in your environment?

In my board interrupt is not populated. So it is good to know RTC test which involves
IRQ is passing in your environment.

I was still waiting on a review from the DT maintainers on 6/11 to apply
the series.

It should have one, no? Although I am new as of -rc1 and the information
is unlikely to have propagated far maintainers wise.

-Intersil ISL1209/19 I2C RTC/Alarm chip with event in
-
-ISL12X9 have additional pins EVIN and #EVDET for tamper detection, while the
-ISL1208 and ISL1218 do not.  They are all use the same driver with the bindings
-described here, with chip specific properties as noted.
-
-Required properties supported by the device:
- - "compatible": Should be one of the following:
-		- "isil,isl1208"
-		- "isil,isl1209"
-		- "isil,isl1218"
-		- "isil,isl1219"
- - "reg": I2C bus address of the device
-
-Optional properties:
- - "interrupt-names": list which may contains "irq" and "evdet"
-	evdet applies to isl1209 and isl1219 only
- - "interrupts": list of interrupts for "irq" and "evdet"
-	evdet applies to isl1209 and isl1219 only
- - "isil,ev-evienb": Enable or disable internal pull on EVIN pin
-	Applies to isl1209 and isl1219 only
-	Possible values are 0 and 1
-	Value 0 enables internal pull-up on evin pin, 1 disables it.
-	Default will leave the non-volatile configuration of the pullup
-	as is.
-
-Example isl1219 node with #IRQ pin connected to SoC gpio1 pin12 and #EVDET pin
-connected to SoC gpio2 pin 24 and internal pull-up enabled in EVIN pin.
