This patch includes following changes :
* Adds gpio pin numbering support for EXYNOS SOCs.
  To have consistent 0..n-1 GPIO numbering the banks are divided
  into different parts where ever they have holes in them.

* Rename GPIO definitions from GPIO_... to S5P_GPIO_...
  These changes were done to enable cmd_gpio for EXYNOS and
  cmd_gpio has GPIO_INPUT same as s5p_gpio driver and hence
  getting a error during compilation.

* Adds support for name to gpio conversion in s5p_gpio to enable
  gpio command EXYNOS SoCs. Function has been added to asm/gpio.h
  to decode the input gpio name to gpio number.
  Example: SMDK5420 # gpio set gpa00

Hi, Akshay.

Did you test exynos4 board?
I have tested your patch-set with the exynos4 board(TRATS2).
It didn't work. 

Occurred DATA_ABORT.
gpio_set_pull(EXYNOS4x12_GPIO_X15,...);

Add the comment at below.

Why did you use the "#if 0 ~ #endif".
If it didn't need to use, it can be removed, isn't?

You introduced new method for gpio numbering and I don't know why are 
you using macro like this:
"exynos_gpio_get(2, EXYNOS4X12_GPIO_X33)"
and also new style like only "EXYNOS4X12_GPIO_X33".

Those are two different numbers and can't be given to s5p_gpio driver 
which interprets only new gpio numbering method.
This code can't work properly.

Please remove old macros and use only proper gpio enum in boards config 
files.
We don't need any "get" macro if all gpio numbers are defined explicitly.

You should also modify proper dts files in arch/arm/dts/* .

I tested your changes with enums only and after change proper dts file 
for trats2 there is still data abort.
So this means that probably enums are not mapped correctly to proper 
gpio bank addresses.

Do you have an documentation for Exynos4 socs?

I think that this should be checked again with documentation and 
compiled next to the current code which is simple and just works.

There are also some warnings when checking by checkpatch script.

Thanks
