Subject: [PATCH v14 28/28] drm/connector: Update docs of "colorspace" for color format prop
Date: Thu, 23 Apr 2026 21:03:51 +0200 [thread overview]
Message-ID: <20260423-color-format-v14-28-449a419ccbd4@collabora.com> (raw)
In-Reply-To: <20260423-color-format-v14-0-449a419ccbd4@collabora.com>
The colorspace property's documentation states that BT2020_RGB and
BT2020_YCC are equivalent, and the output format depends on the driver.
Now that there is a "color format" property that userspace can use to
explicitly set a format, update the colorspace docs to mention this.
The behaviour here is not changed for userspace that doesn't know about
the color format property yet, as the color format property defaults to
"AUTO", where the choice of output format is left up to drivers.
