This patchseries adds multiplexed I2C bus support to barebox
and a driver for pca954x bus multiplexer.
This series has the "RFC" status mostly because of these
adapter numbering hack in drivers/i2c/i2c-mux.c:
/* FIXME */
// priv->adap.nr = mux_dev->id;
priv->adap.nr = -1;
ret = i2c_add_numbered_adapter(&priv->adap);
