Merge tag 'devicetree-for-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux

Pull devicetree updates from Rob Herring:
 "DT Bindings:

   - Convert samsung,exynos5-dp, atmel,lcdc, aspeed,ast2400-wdt bindings
     to schemas

   - Add bindings for Allwinner H616 NMI controller, Renesas r8a779g0
     irqc, Renesas R-Car V4M TMU and CMT timers, Freescale S32G3
     linflexuart, and Mediatek MT7988 XHCI

   - Add 'reg' constraints on DSI and SPI display panels

   - More dropping of unnecessary quotes in schemas

   - Use full paths rather than relative paths in schema $refs

   - Drop redundant storing of phandle for reserved memory

  DT Core:

   - Use scope based cleanups for kfree() and of_node_put()

   - Track interrupt-map and power-supplies for fw_devlink

   - Add buffer overflow check in of_modalias()

   - Add and use __of_prop_free() helper for freeing struct property"

+description:
+  The LCD Controller (LCDC) consists of logic for transferring LCD image data
+  from an external display buffer to a TFT LCD panel. The LCDC has one display
+  input buffer per layer that fetches pixels through the single bus host
+  interface and a look-up table to allow palletized display configurations. The
+  LCDC is programmable on a per layer basis, and supports different LCD
+  resolutions, window sizes, image formats and pixel depths.
