Subject: [PATCH v2 12/36] drm/vc4: hdmi: Add support for BCM2712 HDMI
controllers
From: Maxime Ripard <mripard@...nel.org>
The HDMI controllers found in the BCM2712 are largely the ones found in
the BCM2711 with a different PHY.
There's some difference with how timings are split between registers,
and HDMI1 is now able to run at 4k/60Hz.
