 "Bindings:

   - Convert smsc,lan91c111, qcom,spi-qup, qcom,msm-uartdm,
     qcom,i2c-qup, qcom,gsbi, i2c-mt65xx, TI wkup_m3_ipc (and new
     props), qcom,smp2p, TI timer, Mediatek gnss, Mediatek topckgen,
     Mediatek apmixedsys, Mediatek infracfg, fsl,ls-extirq,
     fsl,layerscape-dcfg, QCom PMIC SPMI, rda,8810pl-timer, Xilinx
     zynqmp_ipi, uniphier-pcie, and Ilitek touchscreen controllers

   - Convert various Arm Ltd peripheral IP bindings to schemas

   - New bindings for Menlo board CPLD, DH electronics board CPLD,
     Qualcomm Geni based QUP I2C, Renesas RZ/G2UL OSTM, Broafcom BCM4751
     GNSS, MT6360 PMIC, ASIX USB Ethernet controllers, and
     Microchip/SMSC LAN95xx USB Ethernet controllers

   - Add vendor prefix for Enclustra

   - Add various compatible string additions

   - Various example fixes and cleanups

   - Remove unused hisilicon,hi6220-reset binding

   - Treewide fix properties missing type definition

   - Drop some empty and unreferenced .txt bindings

   - Documentation improvements for writing schemas

  DT driver core:

   - Drop static IRQ resources for DT platform devices as IRQ setup is
     dynamic and drivers have all been converted to use
     platform_get_irq() and friends

   - Rework memory allocations and frees for overlays

   - Continue overlay notifier callbacks on successful calls and add
     unittests

   - Handle 'interrupts-extended' in early DT IRQ setup

   - Fix of_property_read_string() errors to match documentation

   - Ignore disabled nodes in FDT API calls"
