*	i2c-mux: Add support for device auto-detection	Jean Delvare	2012-10-05	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	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 generic I2C multiplexer using pinctrl API	Stephen Warren	2012-06-04	1	-0/+279
	This is useful for SoCs whose I2C module's signals can be routed to different sets of pins at run-time, using the pinctrl API. +-----+ +-----+ \| dev \| \| dev \| +------------------------+ +-----+ +-----+ \| SoC \| \| \| \| /----\|------+--------+ \| +---+ +------+ \| child bus A, on first set of pins \| \|I2C\|---\|Pinmux\| \| \| +---+ +------+ \| child bus B, on second set of pins \| \----\|------+--------+--------+ \| \| \| \| \| +------------------------+ +-----+ +-----+ +-----+ \| dev \| \| dev \| \| dev \| +-----+ +-----+ +-----+ Signed-off-by: Stephen Warren <swarren@nvidia.com> Acked-by: Linus Walleij <linus.walleij@linaro.org> Acked-by: Rob Herring <rob.herring@calxeda.com> Signed-off-by: Wolfram Sang <w.sang@pengutronix.de>
