   4 Subject: [PATCH] dts: rp1: Add spi6, fix spi1 #address-cells
   5
   6 spi6 won't be useful on Pi 5 because it can't be enabled on the 40-pin
   7 header, but include it for completeness.
   8
   9 Also fix the #address-cells value for spi1, otherwise the kernel will
  10 reject attempts to apply the, say, spi1-2cs overlay at runtime.
