$ dtoverlay -h spi2-2cs-pi5
Name: spi2-2cs-pi5
Info: Enables spi2 on GPIOs 1-3 with two chip select (CS) lines and
 associated spidev dev nodes. The gpio pin numbers for the CS lines and
 spidev device node creation are configurable. Pi 5 only.
Usage: dtoverlay=spi2-2cs-pi5,<param>=<val>
Params: cs0_pin GPIO pin for CS0 (default 0).
 cs1_pin GPIO pin for CS1 (default 24).
 cs0_spidev Set to 'off' to stop the creation of a
 userspace device node /dev/spidev2.0 (default
 is 'on' or enabled).
 cs1_spidev Set to 'off' to stop the creation of a
 userspace device node /dev/spidev2.1 (default
 is 'on' or enabled).
