HSI framework

Hi Linus,

I have been working in an HSI framework. The High Speed Synchronous Serial Interface (HSI) is a serial interface mainly used for connecting application engines (APE) with cellular modem engines (CMT) in cellular handsets.

The framework is currently being used for some people and we would like to see it integrated into the kernel for 3.3. There is no HW controller drivers in this pull, but some people have already some of them pending which they would like to push as soon as this integrated. I am also working on the acceptance for an TI OMAP one, based on a compatible legacy version of the interface called SSI.

Please see the latest discussion thread about the framework patches here:

https://lkml.org/lkml/2011/6/10/280

Here thread discussion for integration:

https://lkml.org/lkml/2011/10/20/177

Here, the thread discussion to add the hsi repository to linux-next:

https://lkml.org/lkml/2011/10/28/69

The patches have been sitting for a while in linux-next without issues.

The signed tag covering those commits: hsi_for_3.3

Thanks & Br,
Carlos Chinea

Hi Linus,

I've noticed that you have not pulled this (yet). I would like to confirm that we at Intel are also very interested to have HSI upstream.

I believe this code base is more than worth merging since it has many users and it has proven itself in real Nokia products. Would you please pull it?

Best Regards,
Artem Bityutskiy

Hi,

I think we never got a reply why the HSI framework has not been pulled into 3.3. So what needs to be done to get it pulled into 3.4?

Hi,

Because this question is for Linus, he should be in "To:" instead of "Cc:" - correcting.

Best Regards,
