Subject: [PATCH v4 20/34] drm/omap: Migrate to aggregate driver
Date: Thu,  2 Dec 2021 14:27:18 -0800	[thread overview]
Message-ID: <20211202222732.2453851-21-swboyd@chromium.org> (raw)
In-Reply-To: <20211202222732.2453851-1-swboyd@chromium.org>

Use an aggregate driver instead of component ops so that we can get
proper driver probe ordering of the aggregate device with respect to all
the component devices that make up the aggregate device.
