Merge tag 'renesas-dt-bindings-for-v4.14' of https://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas into next/dt

Pull "Renesas ARM Based SoC DT Bindings Updates for v4.14" from Simon Horman:

* Document R-Car D3 (r8a77995) SoC and Draak board

* Document reserved SRAM for the SMP jump stub on R-Car Gen2 and RZ/G1 SoCs

  Geert Uytterhoeven says, "+Renesas R-Car Gen2 and RZ/G1 SoCs need a small
  piece of SRAM for the jump stub +for secondary CPU bringup and CPU
  hotplug.  +This memory is reserved by adding a child node to a
  "mmio-sram" node..."

* Add a VSP channel index to DU vsps

  Laurent Pinchart says, "multiple LIF instances in the VSP. The current DT
  bindings don't support specifying that kind of SoC integration scheme.
  Extend them with a VSP channel index."

* Add R-Car M3-W (r8a7796) HDMI TX DT bindings

  This is compatible with existing R-Car H3 (r8a7795) support

+* Renesas SMP SRAM

+Renesas R-Car Gen2 and RZ/G1 SoCs need a small piece of SRAM for the jump stub
+for secondary CPU bringup and CPU hotplug.
+This memory is reserved by adding a child node to a "mmio-sram" node, cfr.
