Currently, the I2C buses are probed for HWMON I2C devices, which might
not be acceptable in same cases. This patch makes device probing
configurable through the property "probe" of the FDT I2C device node:

      i2c@3000 {
           ...
           compatible = "fsl-i2c";
           probe;
	    ...
       };

You need to add documentation to booting-without-of.txt about what the
'probe' property means.  Also, 'probe' is a pretty generic term being
used in an i2c specific context.  Can you prefix it with i2c or
something to protect the namespace?  'i2c-probe' perhaps?

In i2c-cpm, I currently use the property "linux,i2c-class" to set the
i2c class directly as documented in dts-bindings/fsl/cpm_qe/cpm/i2c.txt.

We should agree on *one* method to set the i2c class.

Thanks,
Jochen
