Intel Comet Lake has the same LPSS than Intel Cannon Lake.
Add the new IDs to the list of supported devices.

Let's hold a bit. I'd like to double check does the I2C controller use 
Skylake or Broxton derived input clocks.

How come it's not cnl_i2c_info?

This is a good question, that's why Jarkko asked Lee to hold on until
we have confirmation about i2c timings.

I got confirmation I2C uses the same input clock than Cannon Lake and 
matches with my measurements.

Andy: please do s/bxt_i2c_info/cnl_i2c_info/ in your patch.
