Custom driver cofiguration



Hi

I'm working with ANDROID ICS, i tried to implement user LED via GPIO in my android device with the LINUX kernel 3.2. But due to kernel problem i can't use the LED function.

Then i got rowboat-am335x-kernel3.2 now my LED is working fine. Regarding that i have the following questions.

1--> I've same files in kernel/driver/leds In both my old kernel and rowboat-kernel,but when i try to execute ics/rowboat-kernel:$ make menuconfig, i can see LED drivers under Divice Drivers--> LED Support. But i cant see these drivers when i try to execute from my old kernel.

    How they configured the LED drivers features in rowboat-kernel, what are the files they have changed and how they configured.

2-->In rowboat-am335x-kernel3.2 there is no support for USB PRINTER SUPPORT. I've a driver files how can i add my driver with my kernel

Can any one help me ?

Thanks in advance.
