for 5.5, please pull the following:
 
 - Stefan paves the way for supporting the Raspberry Pi 4 and gets rid of
   a bunch of dtc checker warnings by removing incorrect
   nodes/properties, moving BCM2835/6/7 specific nodes into the
   appropriate DTS, converts Raspberry Pi boards to JSON schema, and
   finally adds minimal Raspberry Pi 4 model B support
 
 - Dan adds support for the Luxul XWC-2000 router based on the BCM47094 SoC
 
 - Chris adds a proper label to the Hurricane 2 watchdog controller node
