[PATCH v3 0/4] i2c: omap: patch series related to multimaster mode

2014-11-22 Thread Alexander Kochetkov
Here is the patch series intended to improve stability of
i2c-omap driver in the i2c multimaster environments.

Tested on Beagleboard XM C.
For now all fine. No controller timeouts, no data corruptions.

Also impelemented i2c bus fault detection during startup and
after reset.

So, instead of the message "controller timeout" blaming IP,
you get "timeout waiting for bus ready".

Rebased against i2c/for-next (eb61694b43dea0d43ea2574e7d48f476a6bdffb0)

Tested on the kernel from angstrom-v2013.06-yocto1.4
Kernel recepie linux-mainline_3.2.bb
git://github.com/Angstrom-distribution/meta-ti.git; branch 
angstrom-staging-yocto1.4
With all i2-omap.c patches backported from upstream linux/master
