spi driver for flash & rtc

Hello,

I have some general question:

I need to support in linux 2.6.37, the following spi devices:

1. serial fram - MB85RS2MTPF-G (fujitsu)

2. rtc(real-time clock) rv-3049 (micro crystal)

I've made search in both internet and in linux source code of 2.6.37, but did not find if any of this drivers is supported in Linux.

I would like to ask if you think there is no other option, but to implement these drivers....

Thanks for your feedback,

Ran

    Hi Ran,

    You may not get exact RTC driver for your part no. but you can get similar to that.

    You may need to change that driver as per your new RTC device with your data sheet recommendation.

    Please refer to the following links.
