Merge tag 'devicetree-for-6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull devicetree updates from Rob Herring: "DT Bindings: - Various LED binding conversions and clean-ups. Convert the ir-spi-led, pwm-ir-tx, and gpio-ir-tx LED bindings to schemas. Consistently reference LED common.yaml or multi-led schemas and disallow undefined properties. - Convert IDT 89HPESx, pwm-clock, st,stmipid02, Xilinx PCIe hosts, and fsl,imx-fb bindings to schema - Add ata-generic, Broadcom u-boot environment, and dynamic MTD sub-partitions bindings. - Make all SPI based displays reference spi-peripheral-props.yaml - Fix some schema property regex's which should be fixed strings or were missing start/end anchors - Remove 'status' in examples, again... DT Core: - Fix a possible NULL dereference in overlay functions - Fix kexec reading 32-bit "linux,initrd-{start,end}" values (which never worked) - Add of_address_count() helper to count number of 'reg' entries - Support .dtso extension for DT overlay source files. Rename staging and unittest overlay files. - Update dtc to upstream v1.6.1-63-g55778a03df61" * tag 'devicetree-for-6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux: (42 commits) dt-bindings: leds: Add missing references to common LED schema dt-bindings: leds: intel,lgm: Add missing 'led-gpios' property of: overlay: fix null pointer dereferencing in find_dup_cset_node_entry() and find_dup_cset_prop() dt-bindings: lcdif: Fix constraints for imx8mp media: dt-bindings: atmel,isc: Drop unneeded unevaluatedProperties dt-bindings: Drop Jee Heng Sia dt-bindings: thermal: cooling-devices: Add missing cache related properties dt-bindings: leds: irled: ir-spi-led: convert to DT schema dt-bindings: leds: irled: pwm-ir-tx: convert to DT schema dt-bindings: leds: irled: gpio-ir-tx: convert to DT schema dt-bindings: leds: mt6360: rework to match multi-led dt-bindings: leds: lp55xx: rework to match multi-led dt-bindings: leds: lp55xx: switch to preferred 'gpios' suffix dt-bindings: leds: lp55xx: allow label dt-bindings: leds: use unevaluatedProperties for common.yaml dt-bindings: thermal: tsens: Add SM6115 compatible of/kexec: Fix reading 32-bit "linux,initrd-{start,end}" values dt-bindings: display: Convert fsl,imx-fb.txt to dt-schema dt-bindings: Add missing start and/or end of line regex anchors dt-bindings: qcom,pdc: Add missing compatibles ...

-- interrupt-controller: identifies the node as an interrupt controller

-- #interrupt-cells: specifies the number of cells needed to encode an

-NOTE:
-The core provides a single interrupt for both INTx/MSI messages. So,
-created a interrupt controller node to support 'interrupt-map' DT
-functionality. The driver will create an IRQ domain for this map, decode
-the four INTx interrupts in ISR and route them to this domain.
