I do not see so useful to add an enum for each instance of the I2C bus. And we have to add it if the number of i2c busses grows. IMHO it is better to use directly the constant, so later in another patch pmic_init(5) instead of pmic(I2C_5).
This problem has been already discussed with Heiko:
http://patchwork.ozlabs.org/patch/181789/
I think, that we will have to have an enum of available I2C_x busses at <i2c.h> header file.
In the case of Trats and PMIC framework, the I2C_0 is done on purpose to keep the trats board working (since the PMIC is in reality connected to I2C_5). This numbering (I2C_0) needs to be there until prerequisite patches aren't accepted (the multibus I2C support on trats board)
