Hi,

Changed since v1:
- Now rebased on top of drm-tip.
- No longer ignoring errors from xe_i2c_probe().
- Cleanups pointed out by Lucas.

I've also included followup patches from Raag and Riana to this
series.

Original cover letter:

Some of the future GPUs will provide access to the on-board Synopsys
DesignWare I2C host adapter. The i2c is used to connect various
microcontrollers. The initially supported microcontroller unit is
called Add-In Management Controller (AMC).

Thanks,
