need to upgrade the kernel with RTC ISL1221

[sjremya]

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 only few option 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

hi all


I could find a solution for this ....




I have added the new RTC configuration in /linux/drivers/rtc/Kconfig as shown below, and now i am able to configure the kernel with the new chip

<
config RTC_DRV_ISL1221
tristate "Intersil 1221"
depends on RTC_CLASS && I2C
help
If you say yes here you get support for the
Intersil 1221 RTC chip.
This driver can also be built as a module. If so, the module
will be called rtc-isl1221.

Please correct me if I m doing any thing wrong ....
