Rework the code to have a single implementation of the bounds checks. - Rework of_irq_init() to ignore any implicit interrupt-parent (i.e. in a parent node) on nodes without an interrupt.

dt-bindings: display: bridge: simple: document the ASL CS5263 DP-to-HDMI bridge

2025-11-24T16:54:29Z

The ASL CS5263 is a high-performance DP1.4 to HDMI2.0b converter, designed to connect a DP1.4 source to an HDMI2.0b sink. The CS5263AN integrates a DP1.4 compliant receiver, and a HDMI2.0b compliant transmitter.

Generally at most 1 blank line is the standard style for DT schema files. Remove the few cases with more than 1 so that the yamllint check for this can be enabled.

dt-bindings: display: bridge: renesas,dsi-csi2-tx: Allow panel@ subnode

2025-10-22T06:54:28Z

This controller can have both bridges and panels connected to it. In order to describe panels properly in DT, pull in dsi-controller.yaml and disallow only unevaluatedProperties, because the panel node is optional. Include example binding with panel.
