Just want to understand why these properties are here?  
As these properties are for child dt node. But have not seen
anyone is using here.

That is how gpio_keys node entries are defined in other .dts files.

I have gone through example for address-cells and size-cells in following link:
http://devicetree.org/mediawiki/index.php?title=Device_Tree_Usage&stable=1#CPU_addressing

which indicates that these fields are for child "reg".
I think, here in child node there is no "reg". so there is no use
of address-cells and size-cells propeties.

Correct me if I am wrong here?

I have gone through example for address-cells and size-cells in following link:
http://devicetree.org/mediawiki/index.php?title=Device_Tree_Usage&stable=1#CPU_addressing

which indicates that these fields are for child "reg".
I think, here in child node there is no "reg". so there is no use
of address-cells and size-cells propeties.

Correct me if I am wrong here?

Please check Documentation/devicetree/bindings/gpio/gpio_keys.txt

And whether these properties are required or not, I will let device tree
experts to comment on that.

As such, currently all node entries for gpio_keys use these properties.

you can just verify by a simple test.
delete the 2 lines. address-cells and size cells.
this will have no affect.
now with these 2 lines deleted lines add a dummy reg property with
address and cell. dtb compiler will warn.
So I think what manish reffered is right.
There is also a reference of smdk4210 for kepads.

Right. Compilation is ok even after removing the address-cell and
size-cell properties.

But since this is used across all the instances, I would like to know
the view of the authors on this.

David, Dimitry,

Can you please let us know your opinion on this? If these properties are
not required, then we can remove them from the documentation and from
node entries in several other dts files.

Re: [PATCH 1/5] ARM: dts: exynos5250-arndale: Add node entry for gpio-buttons

[Tomasz Figa]

Hi,

I'm wondering why Exynos5250 has not been migrated to use pinctrl yet.

Support for it in pinctrl-samsung driver has been already merged, but I 
don't see any pinctrl nodes in exynos5250.dtsi.

This is important because the legacy gpio-samsung support is going to be 
dropped, as it already happened in case of Exynos 4.

CC'ing Thomas Abraham as he might know something.

The #address-cells and #size-cells are used only together with reg 
properties of sub nodes. They define how many cells in reg specifier are 
used for registers address and length.

So, if you have #address-cells = <1> and #size-cells = <0>, then your reg 
specifier will be simply <addr>. You can get more complex specifiers using 
more address cells and size cells, like:

#address-cells = <3>;
#size-cells = <1>;

subdev@1,2,3 {
	reg = <1 2 3 0x1000>;
	/* ... */
};

If you don't intend to use reg property for child device addressing then 
you don't define #address-cells and #size-cells properties.

I think that the documentation of gpio_keys binding should be corrected 
and possibly also moved to bindings/input instead of bindings/gpio, as 
this directory is intended to be used for GPIO controllers, not GPIO 
consumers.

The #address-cells and #size-cells are used only together with reg

	/* ... */
};

you don't define #address-cells and #size-cells properties.

Tushar and all,

I agree with Tomasz's opinion to support pinctrl instead of gpio on exynos5250
stuff.

Please re-submit with using pinctrl is in samsung tree.

If any problems, please let us know.

Thanks.
