Subject: [PATCH 8/8] drm/msm/dpu: add SM8250 to hw catalog
Date: Mon, 25 May 2020 23:22:15 -0400	[thread overview]
Message-ID: <20200526032235.21930-9-jonathan@marek.ca> (raw)
In-Reply-To: <20200526032235.21930-1-jonathan@marek.ca>

This brings up basic video mode functionality for SM8250 DPU. Command mode
and dual mixer/intf configurations are not working, future patches will
address this. Scaler functionality and multiple planes is also untested.
