2010-01-16i2c/pca: Don't use *_interruptibleWolfram Sang
Unexpected signals can disturb the bus-handling and lock it up. Don't use interruptible in 'wait_event_*' and 'wake_*' as in commits dc1972d02747d2170fb1d78d114801f5ecb27506 (for cpm), 1ab082d7cbd0f34e39a5396cc6340c00bc5d66ef (for mpc), b7af349b175af45f9d87b3bf3f0a221e1831ed39 (for omap).

2009-06-16i2c: Use resource_size macroLinus Walleij
This replace all instances in the i2c busses tree of res->end - res->start + 1 with the handy macro resource_size(res) from ioport.h (coming in from platform_device.h). This was created with a simple sed -i -e 's/\([a-z]*\)->end *- *[a-z]*->start *+ *1/resource_size(\1)/g' Then manually replacing the PXA redefiniton of the same kind of macro manually. Recompiled some ARM defconfigs I could find to make a rough test so it shouldn't break anything, though I couldn't see exactly which configs you need for all the drivers.

2009-03-28i2c-algo-pca: Use timeout for checking the state machineWolfram Sang
We now timeout also if the state machine does not change within the given time. For that, the driver-specific completion-functions are extended to return true or false depending on the timeout. This then gets checked in the algorithm. Signed-off-by: Wolfram Sang <w.sang@pengutronix.de> Signed-off-by: Jean Delvare <khali@linux-fr.org>
