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 MMP I2C controller
-
-Required properties :
-
- - reg : Offset and length of the register set for the device
- - compatible : should be "mrvl,mmp-twsi" where mmp is the name of a
- compatible processor, e.g. pxa168, pxa910, mmp2, mmp3.
- For the pxa2xx/pxa3xx, an additional node "mrvl,pxa-i2c" is required
- as shown in the example below.
- For the Armada 3700, the compatible should be "marvell,armada-3700-i2c".
-
-Recommended properties :
-
- - interrupts : the interrupt number
- - mrvl,i2c-polling : Disable interrupt of i2c controller. Polling
- status register of i2c controller instead.
- - mrvl,i2c-fast-mode : Enable fast mode of i2c controller.
-
-Examples:
- twsi1: i2c@d4011000 {
- compatible = "mrvl,mmp-twsi";
- reg = <0xd4011000 0x1000>;
- interrupts = <7>;
- mrvl,i2c-fast-mode;
- };
-
- twsi2: i2c@d4025000 {
- compatible = "mrvl,mmp-twsi";
- reg = <0xd4025000 0x1000>;
- interrupts = <58>;
- };
