[RFC PATCHv4 0/7] HSI framework and drivers
Hi ! Here you have the fourth round of the HSI framework patches. The patch series introduces the HSI framework, an SSI driver for OMAP and a generic character device for HSI/SSI devices. SSI, which is a legacy version of HSI, is used to connect the application engine with the cellular modem on the Nokia N900. In this round we have added/fixed: - Address some comments from Tony Lindgren and Peter Henn. - Add module support to the HSI framework. - Fix sparse warnings in OMAP SSI driver. - Fix module license. - Remove spurious udev events generated by the HSI framework. - Avoid removal of a controller claimed by a client. - Fix hsi_char client device removal. TODO: - Move OMAP SSI to use omap hwmod I would very glad to continue getting feedback about this proposal. This patch series is based on 2.6.37-rc1. Version 3 of the patch set: https://lkml.org/lkml/2010/10/11/60 Note: checkpatch reports a false positive on patch 1/7.

I was sort of asking the same thing. I expected this to be queued up for 2.6.40 so we don't proliferate out-of-tree drivers :-( If Nokia will not pursue this patch set then tell me and Govindraj and we can surely take it over.

We are aiming to release a new version in 3 weeks max, sooner if we can. I am very sorry for the delay and I agree that starting to have several out-of-tree drivers is not acceptable. I'll try my best to fix this asap.

If the HSI framework makes it into the kernel, then I will try to push a couple of new HSI clients needed for rx51 and the platform related code. > > P.S.: 3 weeks are over today :) > Yep, we are almost there with the patches :P A small problem in a last minute test is keeping us from releasing the patches already.
