Subject: [PATCH v4 01/17] drm/i915/pxp: Define PXP component interface
Date: Mon, 24 May 2021 22:47:47 -0700 [thread overview]
Message-ID: <20210525054803.7387-2-daniele.ceraolospurio@intel.com> (raw)
In-Reply-To: <20210525054803.7387-1-daniele.ceraolospurio@intel.com>
This will be used for communication between the i915 driver and the mei
one. Defining it in a stand-alone patch to avoid circualr dependedencies
between the patches modifying the 2 drivers.
Split out from an original patch from Huang, Sean Z
