Subject: [PATCH v4 13/29] drm/rockchip: inno_hdmi: Drop HDMI Vendor Infoframe support
Date: Fri, 22 Dec 2023 18:42:04 +0100

From: Maxime Ripard <mripard@kernel.org>

The HDMI vendor infoframe is only meant to be sent with 4k60 modes and
higher, but the controller doesn't support them. Let's drop them from
the kernel.
