   4 Subject: [PATCH] ARM: dts: Provide WLAN firmware names for Zero 2 W
   5
   6 BCM43430/2 may be BCM43430B0 or BCM43436P, and BCM43430/1 can be either
   7 BCM43430A1 or BCM43436S, the former being upstream names and the
   8 latter downstream names for differently-sourced sister parts.
   9
  10 Make the choice of firmwares board-specific (without making the actual
  11 firmwares board-specific) by placing the alternative firmware names for
  12 each part in the DT node.
