[RFC PATCH 0/4] i2c: core: introduce master_xfer_irqless

To keep the discussion about master_xfer_irqless going, I post here a
draft how I envision the changes to the I2C core. They are only build
tested. I am unsure if I can test them on hardware before next week, so
I'll send them around as RFC already, so people can get an idea and
comment. Maybe Stefan has some bandwidth to test his imx driver
implementation on top of this?

A branch can be found here:

Happy hacking and thanks for all the input to this,
