need to upgrade kernel with driver- ISL1221 RTC

Hi all

i m a beginner in device drivers.

I m using linux kernel 2-6-20 , which is for our application with AT91SAM9260 processor.

I would like to use an RTC to update my system time, the chip is RTC - ISL1221 from intersil.

This kernel is supporting ISL 1208 but not ISL 1221 . [ I could see few options in kernel configuration time, but ISL 1221 is not present in the device drivers-> real time clock -> RTC drivers list. ]


HOW CAN I CONFIGURE THIS KERNEL FOR THIS NEW RTC
, if i write a driver for this?

Please help me out

Regards

SJR
