Hi Frank,
Why not you use aliases on DTS instead of changing driver?
You can alias the bus number with the child node name. On the following, the bus
will be registerd as 6, 7, 8 and 9.
i2c-core already support this.
aliases {
i2c6 = &pca9546_i2c0;
i2c7 = &pca9546_i2c1;
i2c8 = &pca9546_i2c2;
i2c9 = &pca9546_i2c3;
};
Well, this seems to work indeed for newer kernels. I was originally working on
3.8 that did not yet have this feature. However, this is kind of an hard to find
feature. I didn't see any references in the i2c device tree bindings
documentation. So, unless you actually read the i2c core code, it is very easy
to miss.
Anyway, feel free to disregard my patch.
Frank
