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 ...

-* Marvell PXA GPIO controller
-
-Required properties:
-- compatible : Should be "intel,pxa25x-gpio", "intel,pxa26x-gpio",
- "intel,pxa27x-gpio", "intel,pxa3xx-gpio",
- "marvell,pxa93x-gpio", "marvell,mmp-gpio",
- "marvell,mmp2-gpio" or marvell,pxa1928-gpio.
-- reg : Address and length of the register set for the device
-- interrupts : Should be the port interrupt shared by all gpio pins.
- There're three gpio interrupts in arch-pxa, and they're gpio0,
- gpio1 and gpio_mux. There're only one gpio interrupt in arch-mmp,
- gpio_mux.
-- interrupt-names : Should be the names of irq resources. Each interrupt
- uses its own interrupt name, so there should be as many interrupt names
- as referenced interrupts.
-- interrupt-controller : Identifies the node as an interrupt controller.
-- #interrupt-cells: Specifies the number of cells needed to encode an
- interrupt source.
-- gpio-controller : Marks the device node as a gpio controller.
-- #gpio-cells : Should be two. The first cell is the pin number and
- the second cell is used to specify flags. See gpio.txt for possible
- values.
-
-Example for a MMP platform:
-
- gpio: gpio@d4019000 {
- compatible = "marvell,mmp-gpio";
- reg = <0xd4019000 0x1000>;
- interrupts = <49>;
- interrupt-names = "gpio_mux";
- gpio-controller;
- #gpio-cells = <2>;
- interrupt-controller;
- #interrupt-cells = <1>;
- };
-
-Example for a PXA3xx platform:
-
- gpio: gpio@40e00000 {
- compatible = "intel,pxa3xx-gpio";
- reg = <0x40e00000 0x10000>;
- interrupt-names = "gpio0", "gpio1", "gpio_mux";
- interrupts = <8 9 10>;
- gpio-controller;
- #gpio-cells = <0x2>;
- interrupt-controller;
- #interrupt-cells = <0x2>;
- };
