Subject: [PATCH v1 0/2] drm/xe: i2c support

Hi,

Some of the future "data center 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,

Heikki Krogerus (2):
