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 Signed-off-by: Alexander Kochetkov <al.kochet@xxxxxxxxx> Alexander Kochetkov (4): i2c: omap: cleanup register definitions i2c: omap: implement workaround for handling invalid BB-bit values i2c: omap: don't reset controller if Arbitration Lost detected i2c: omap: add notes related to i2c multimaster mode drivers/i2c/busses/i2c-omap.c | 131 +++++++++++++++++++++++++++++++++++++++-- 1 file changed, 125 insertions(+), 6 deletions(-) -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
