[PATCH 0/1] dt-bindings: media: convert hix5hd2-ir to DT schema

[Pranav Kharche <pranavkharche7@gmail.com>]

This patch converts the HiSilicon hix5hd2 IR remote controller binding from
legacy plaintext format to JSON Schema (DT schema) YAML format. This is part
of the GSoC 2026 Device Tree Bindings conversion project.

The conversion includes:
- Standardized property definitions with proper types and constraints
- Reference to rc.yaml for common IR remote controller properties
- Proper example device tree node with GIC interrupt specifiers
- Support for schema-based validation of device tree sources

Validation Results:
1. Binding schema check passed:
   $ make dt_binding_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/media/hix5hd2-ir.yaml
   ✓ PASSED

2. DTB validation with actual IR node passed:
   $ ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- make CHECK_DTBS=y DT_SCHEMA_FILES=Documentation/devicetree/bindings/media/hix5hd2-ir.yaml hisilicon/hi3798cv200-poplar.dtb
   ✓ PASSED

The binding correctly validates the IR controller found in hix5hd2 and
hi3796cv300 HiSilicon SoCs.
