Subject: [PATCH v3 060/105] drm/vc4: crtc: Make state functions public
Date:   Wed, 27 May 2020 17:48:30 +0200
Message-Id: <8d86964fb69d9d2d681dd3cab914bedd4e24b728.1590594512.git-series.maxime@cerno.tech>

We'll need the CRTC state related functions to be exported so that we can
reuse them for the TXP.
