While the bus8is not visible to the Linux Kernel, drivers need to send and receive9commands via the bus. The Linux Kernel driver abstraction has support to10implement different drivers for each component inside an I²C bus, as if11the bus were visible to the main system board.12 13One of the problems with I²C devices is that sometimes the same device may14work with different I²C hardware. This is common, for example, on devices15that comes with a tuner for North America market, and another one for16Europe. Some drivers have a ``tuner=`` modprobe parameter to allow using a17different tuner number in order to address such issue.18 19The current supported of I²C drivers (not including staging drivers) are20listed below.21 22Audio decoders, processors and mixers23-------------------------------------24 25============ ==========================================================26Driver
