Merge tag 'devicetree-for-5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux

Pull devicetree updates from Rob Herring:

 - Refine reserved memory nomap handling

 - Merge some PCI and non-PCI address handling implementations

 - Simplify of_address.h header ifdefs

 - Improve printk handling of some 64-bit types

 - Convert adi,adv7511, Arm ccree, Arm SCMI, Arm SCU, Arm TWD timer, Arm
   VIC, arm,sbsa-gwdt, Arm/Amlogic SCPI, Aspeed I2C, Broadcom iProc PWM,
   linaro,optee-tz, MDIO GPIO, Mediatek RNG, MTD physmap, NXP
   pcf8563/pcf85263/pcf85363, Renesas TPU, renesas,emev2-smu,
   renesas,r9a06g032-sysctrl, sysc-rmobile, Tegra20 EMC, TI AM56 PCI, TI
   OMAP mailbox, TI SCI bindings, virtio-mmio, Zynq FPGA, and ZynqMP RTC
   to DT schema

 - Convert mux and mux controller bindings to schema. This includes MDIO
   IIO, and I2C muxes.

 - Add Arm PL031 RTC binding schema

 - Add vendor prefixes for StarFive Technology Co. Ltd. and Insignal Ltd

 - Fix some stale doc references

 - Remove stale property-units.txt. Superseded by schema in dt-schema
   repo.

 - Fixes for 'unevaluatedProperties' handling (enabled with experimental
   json-schema support)

 - Drop redundant usage of minItems and maxItems across the tree

 - Update some examples to use bindings with a schema

-I/O channel multiplexer bindings
-
-If a multiplexer is used to select which hardware signal is fed to
-e.g. an ADC channel, these bindings describe that situation.
-
-Required properties:
-- compatible : "io-channel-mux"
-- io-channels : Channel node of the parent channel that has multiplexed
-		input.
-- io-channel-names : Should be "parent".
-- #address-cells = <1>;
-- #size-cells = <0>;
-- mux-controls : Mux controller node to use for operating the mux
-- channels : List of strings, labeling the mux controller states.

-For each non-empty string in the channels property, an io-channel will

-the list of strings in the channels property, and also matches the mux
-controller state. The mux controller state is described in

-	mux: mux-controller {
