Merge tag 'devicetree-for-6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux

Pull devicetree updates from Rob Herring:
 "Bindings:

   - Add spi-peripheral-props.yaml references to various SPI device
     bindings

   - Convert qcom,pm8916-wdt, ds1307, Qualcomm BAM DMA, is31fl319x,
     skyworks,aat1290, Rockchip EMAC, gpio-ir-receiver, ahci-ceva, Arm
     CCN PMU, rda,8810pl-intc, sil,sii9022, ps2-gpio, and
     arm-firmware-suite bindings to DT schema format

   - New bindings for Arm virtual platforms display, Qualcomm IMEM
     memory region, Samsung S5PV210 ChipID, EM Microelectronic EM3027
     RTC, and arm,cortex-a78ae

   - Add vendor prefixes for asrock, bytedance, hxt, ingrasys, inventec,
     quanta, and densitron

   - Add missing MSI and IOMMU properties to host-generic-pci

   - Remove bindings for removed EFM32 platform

   - Remove old chosen.txt binding (replaced by schema)

   - Treewide add missing type information for properties

   - Treewide fixing of typos and its vs. it's in bindings. Its all good
     now.

   - Drop unnecessary quoting in power related schemas

   - Several LED binding updates which didn't get picked up

   - Move various bindings to proper directories

  DT core code:

   - Convert unittest GPIO related tests to use fwnode

   - Check ima-kexec-buffer against memory bounds

   - Print reserved-memory allocation/reservation failures as errors

   - Cleanup early_init_dt_reserve_memory_arch()

   - Simplify of_overlay_fdt_apply() tail"
