Subject: [PATCH 11/24] drm/msm/mdp5: Add more stuff to CRTC state
Date: Thu, 23 Mar 2017 15:58:04 +0530	[thread overview]
Message-ID: <20170323102817.15017-12-architt@codeaurora.org> (raw)
In-Reply-To: <20170323102817.15017-1-architt@codeaurora.org>

Things like vblank/err irq masks, mode of operation (command mode or not)
are derivative of the interface and mixer state. Therefore, they need to
be a part of the CRTC state too.

Add them to mdp5_crtc_state, and assign them in the CRTC's atomic_check()
func, so that it can be rolled back to a clean state.
