Hi Mike and Mark,

Thanks for your help.

But, I've got a bit of problem again.
I have modified for GPIO standard I/F referring other accepted GPIO driver.

According to Documentation/gpio.txt,
I tried to create GPIO node like below.

[root@localhost gpio]# ls
export  gpiochip244  unexport
[root@localhost gpio]# echo 1 > export
bash: echo: write error: Invalid argument
[root@localhost gpio]#

But it fails.

Could you teach me the reason/cause why?

Thanks, Ohtake(OKISemi)
