Hi,

On behalf of Heikki, since he's on vacation.

Changed since v6:
- Fix SPDX checkpatch warning.

Changed since v5:
- The modification to the dw_i2c_plat_probe() is split into its own
  patch as proposed by Andi.
- I removed completely the comment from the last patch in the series
  ("drm/xe/xe_i2c: Add support for i2c in survivability mode").

Changed since v4:
- Cleanups requested by Andy.
- Casting the PCI power modes to make sparse happy - Raag.
- Limiting the use of this thing to Battlemage again. But I'm not sure
  if this is the correct thing to do.

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,
