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.
