Read GPIO pins directly from register...!!

Hi, I want to read GPIO value directly from register.

Below i explain what i have to do

In my application i want to send data on GPIO and also read from GPIO pins
for that i have develop one module . in that i am using ioctl and read for
send to receive from GPIO pins. Write data on GPIO pins using ioctl it's
work fine but when i am going to read value from GPIO pins using read
system call from userspace . but it's take time.But i want to read GPIO as
much as fast. for that i want to read GPIO pins directly from register.

I hope you can understand what i have to do.


Let me know solution...!!
