This patch adds runtime PM support for the I2C bus in a similar way that
has been done for PCI bus already. This means that the I2C bus core

Hi All,
I was wondering whether it would be reasonable to create a generic
Linux dummy I2C bus controller driver. The rationale behind it is
there might be hardware configurations where I2C communication is
handled by firmware but still it is useful to have I2C slave devices

Won't this break i2c client devices that use runtime PM? Not sure
