Subject: [PATCH v4 15/29] drm/rockchip: inno_hdmi: Switch to infoframe type
Date: Fri, 22 Dec 2023 18:42:06 +0100

From: Maxime Ripard <mripard@kernel.org>

The inno_hdmi driver relies on its own internal infoframe type matching
the hardware.

This works fine, but in order to make further reworks easier, let's
switch to the HDMI spec definition of those types.
