i2c: Make the return type of i2c_del_mux_adapter() void

2013-04-02T05:07:32Z

i2c_del_mux_adapter always returns 0 and none of it current users check its return value anyway. It is also an essential requirement of the Linux device driver model, that functions which may be called from a device's remove callback to free resources provided by the device, are not allowed to fail. This is the case for i2c_del_mux_adapter(), so make its return type void to make the fact that it won't fail explicit.

i2c-mux: Add support for device auto-detection

2012-10-05T20:23:51Z

Let I2C bus segments behind multiplexers have a class. This allows for device auto-detection on these segments. As long as parent segments don't share the same class, it should be fine. I implemented support in drivers i2c-mux-gpio and i2c-mux-pca954x. I left i2c-mux-pca9541 and i2c-mux-pinctrl alone for the moment as I don't know if this feature makes sense for the use cases of these drivers.

i2c: Add a struct device * parameter to i2c_add_mux_adapter()

2012-05-12T12:28:15Z

And adjust all callers. The new device parameter is used in the next patch to initialize the mux's of_node so that its children may be automatically populated. Signed-off-by: David Daney Tested-by: Lars-Peter Clausen Signed-off-by: Wolfram Sang

i2c: Multiplexed I2C bus core support

2010-08-11T16:21:02Z

Add multiplexed bus core support. I2C multiplexer and switches like pca954x get instantiated as new adapters per port. Signed-off-by: Michael Lawnick Acked-by: Rodolfo Giometti Signed-off-by: Jean Delvare
