2026-01-09dt-bindings: display: rockchip: Add no-hpd for dw-hdmi-qp controllerChris Morgan
Add an attribute of "no-hpd" for the Rockchip dw-hdmi-qp controller. This is used to describe implementations where the HPD pin is not connected or used for other purposes, such as in the RK3588S based Gameforce Ace which repurposed the GPIO for an additional face button. The "no-hpd" option was chosen to be consistent with other devices which already define this parameter for broken or missing hpd functionality.

2025-12-15dt-bindings: display: rockchip: dw-hdmi: Add compatible for RK3368 HDMIHeiko Stuebner
Define a new compatible for RK3368 HDMI. The RK3368 HDMI also uses a PHY internal to the controller, so works similar to other controllers, with the exception that the RK3368 only has one VOP, so there is no source selection needed.

Convert cdn-dp-rockchip.txt to yaml. Add new "port@1" property which represents the CDN DP output to keep the same style as the other display interfaces. This patch also changes the constraints for "phys" and "extcon". For the original binding, only one phy and the corresponding extcon can be specified. In the new binding, one or two phys can be specified. Since the RK3399 has two DP-USB PHYs, specifying one allows output via the corresponding PHY, while specifying two lets the driver choose one PHY for output. This rule also applies to extcon, which provides the cable state for the corresponding PHY.

The hdmi-connector nodes are now functional and the new way to model hdmi ports nodes with both in and output port subnodes. Unfortunately with the conversion to YAML the old method with only an input port node was used. Later the new method was also added to the binding. A binding must be unambiguously, so remove the old port property entirely and make port@0 and port@1 a requirement as all upstream dts files are updated as well and because checking deprecated stuff is a bit pointless. Update the example to avoid use of the removed property.
