Subject: [PATCH v14 22/28] drm/connector: Register color format property on HDMI connectors

From: Nicolas Frattaroli <[email-masked]>
Date: Thu, 23 Apr 2026 21:03:45 +0200

The drmm_connector_hdmi_init function can figure out what DRM color
formats are supported by a particular connector based on the supported
HDMI format bitmask that's passed in.

Use it to register the drm color format property.
