Subject: [PATCH v1 0/2] drm/xe: i2c support
Date: Fri, 30 May 2025 17:17:42 +0300 [thread overview]
Message-ID: <20250530141744.3605983-1-heikki.krogerus@linux.intel.com> (raw)
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):
