Merge tag 'devicetree-for-5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull Devicetree updates from Rob Herring: - Improve device links cycle detection and breaking. Add more bindings for device link dependencies. - Refactor parsing 'no-map' in __reserved_mem_alloc_size() - Improve DT unittest 'ranges' and 'dma-ranges' test case to check differing cell sizes - Various http to https link conversions - Add a schema check to prevent 'syscon' from being used by itself without a more specific compatible - A bunch more DT binding conversions to schema * tag 'devicetree-for-5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux: (55 commits) of: reserved-memory: remove duplicated call to of_get_flat_dt_prop() for no-map node of: unittest: Use bigger address cells to catch parser regressions dt-bindings: memory-controllers: Convert mmdc to json-schema dt-bindings: mtd: Convert imx nand to json-schema dt-bindings: mtd: Convert gpmi nand to json-schema dt-bindings: iio: io-channel-mux: Fix compatible string in example code of: property: Add device link support for pinctrl-0 through pinctrl-8 of: property: Add device link support for multiple DT bindings dt-bindings: phy: ti: phy-gmii-sel: convert bindings to json-schema dt-bindings: mux: mux.h: drop a duplicated word dt-bindings: misc: Convert olpc,xo1.75-ec to json-schema dt-bindings: aspeed-lpc: Replace HTTP links with HTTPS ones dt-bindings: drm/bridge: Replace HTTP links with HTTPS ones drm/tilcdc: Replace HTTP links with HTTPS ones dt-bindings: iommu: renesas,ipmmu-vmsa: Add r8a774e1 support dt-bindings: fpga: Replace HTTP links with HTTPS ones dt-bindings: virtio: Replace HTTP links with HTTPS ones dt-bindings: media: imx274: Add optional input clock and supplies dt-bindings: i2c-gpio: Use 'deprecated' keyword on deprecated properties dt-bindings: interrupt-controller: Fix typos in loongson,liointc.yaml ...

-DT bindings for the Renesas RZ/A1 Interrupt Controller
-
-The RZ/A1 Interrupt Controller is a front-end for the GIC found on Renesas
-RZ/A1 and RZ/A2 SoCs:
- - IRQ sense select for 8 external interrupts, 1:1-mapped to 8 GIC SPI
- interrupts,
- - NMI edge select.
-
-Required properties:
- - compatible: Must be "renesas,<soctype>-irqc", and "renesas,rza1-irqc" as
- fallback.
- Examples with soctypes are:
- - "renesas,r7s72100-irqc" (RZ/A1H)
- - "renesas,r7s9210-irqc" (RZ/A2M)
- - #interrupt-cells: Must be 2 (an interrupt index and flags, as defined
- in interrupts.txt in this directory)
- - #address-cells: Must be zero
- - interrupt-controller: Marks the device as an interrupt controller
- - reg: Base address and length of the memory resource used by the interrupt
- controller
- - interrupt-map: Specifies the mapping from external interrupts to GIC
- interrupts
- - interrupt-map-mask: Must be <7 0>
-
-Example:
-
- irqc: interrupt-controller@fcfef800 {
- compatible = "renesas,r7s72100-irqc", "renesas,rza1-irqc";
- #interrupt-cells = <2>;
- #address-cells = <0>;
- interrupt-controller;
- reg = <0xfcfef800 0x6>;
- interrupt-map =
- <0 0 &gic GIC_SPI 0 IRQ_TYPE_LEVEL_HIGH>,
- <1 0 &gic GIC_SPI 1 IRQ_TYPE_LEVEL_HIGH>,
- <2 0 &gic GIC_SPI 2 IRQ_TYPE_LEVEL_HIGH>,
- <3 0 &gic GIC_SPI 3 IRQ_TYPE_LEVEL_HIGH>,
- <4 0 &gic GIC_SPI 4 IRQ_TYPE_LEVEL_HIGH>,
- <5 0 &gic GIC_SPI 5 IRQ_TYPE_LEVEL_HIGH>,
- <6 0 &gic GIC_SPI 6 IRQ_TYPE_LEVEL_HIGH>,
- <7 0 &gic GIC_SPI 7 IRQ_TYPE_LEVEL_HIGH>;
- interrupt-map-mask = <7 0>;
- };
