[PATCH v4 0/4] drm/xe: i2c support

[Heikki Krogerus <heikki.krogerus@linux.intel.com>]

Hi,

Changed since v3:
- Cleanups as requested by Rodrigo.
- The licence is now changed, but still need confirmation for it!

Changed since v2:
- Added dependency on regmap when i2c is enabled.

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,
