From cd66a0832351762b496bdce6f2f94a871d11484e Mon Sep 17 00:00:00 2001 From: Phil Elwell Date: Thu, 2 Nov 2023 13:12:55 +0000 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.
