Subject: [PATCH v2 1/9] dt-bindings: panel: lvds: Add dual-link LVDS display support
Date: Thu, 15 Aug 2019 12:04:25 +0100 [thread overview]
Message-ID: <1565867073-24746-2-git-send-email-fabrizio.castro@bp.renesas.com> (raw)
In-Reply-To: <1565867073-24746-1-git-send-email-fabrizio.castro@bp.renesas.com>
Dual-link LVDS displays have two ports, therefore document this
with the bindings.
Signed-off-by: Fabrizio Castro <fabrizio.castro@bp.renesas.com>
---
v1->v2:
* Reworked the description of the ports property
* lvds0_panel_in in the example has been renamed to panel_in0
* lvds1_panel_in in the example has been renamed to panel_in1
Laurent,
in linux-next they are now working with:
Documentation/devicetree/bindings/display/panel/lvds.yaml
What should I do here?
Thanks,
Fab
