Merge tag 'ixp4xx-dtx-v5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-nomadik into arm/dt

IXP4xx DTS changes for v5.17:

- Add the LEDs to the Freecom FSG-3 that were missing.
- Add a devicetree for the Gorami MultiLink Router
- Add a devicetree for the Gateway GW7001 Router

This completes the migration of all IXP4xx devices to
device tree files.

Next merge window we will delete the remaining board files,
it cannot be done now because of cross-tree dependencies.

* tag 'ixp4xx-dtx-v5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-nomadik:
  ARM: dts: ixp4xx: Add devicetree for Gateway 7001
  ARM: dts: Add Goramo MultiLink device tree
  ARM: dts: Add FSG3 system controller and LEDs
