Subject: [PATCH 0/3] drm: Add connector info/property for non-desktop [v2]

This is the same as the series for non-standard displays but uses the
phrase 'non-desktop' instead. No functional changes.

Subject: [PATCH 2/3] drm/fb: add support for not enabling fbcon on non-desktop displays [v2]

From: Dave Airlie <[email protected]>

We don't want fbcon to get used on non-desktop dislays,
don't pass them as enabled connectors to the fb helper setup.

This prevents my HMD from getting disorted fbcon, and from
affecting other displays console.

v2: Change description from non-standard to non-desktop
