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).
