From cd66a0832351762b496bdce6f2f94a871d11484e Mon Sep 17 00:00:00 2001

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