Device Tree Modification

Can I only enable spidev on spi1 or does it work for spi2 and/or spi3?


You can find the addresses of most devices in the Xavier here:
Xavier Series (SoC) Technical Reference Manual version 1.1
Section 3.1.3, pages 29-71
“System Address Map”

Search for “PINMUX_CFG” because there are multiple different places where pinmux is discussed. Section 8.4 is only the start.

Also: The documentation for the Xavier is surprisingly different from the X1. It’s almost as if two different teams built the documentation from scratch, rather than a continual line of incremental development.
