Subject: [PATCH v5 54/80] drm/vc4: hdmi: Add PHY RNG enable / disable function
Date: Thu, 3 Sep 2020 10:01:26 +0200 [thread overview]
Message-ID: <216155f1c0b83e622ac60a2f7d00eb707de3acba.1599120059.git-series.maxime@cerno.tech> (raw)

Let's continue the implementation of hooks for the parts that change in the
BCM2711 SoC with the PHY RNG setup.
