how to enable spi?
I'm using the 2022-08-08 bookworm rpi4 image from
<https://raspi.debian.net/tested-images/>, it's got linux-image-arm64
5.18.14-1 and raspi-firmware 1.20220331+ds-2.
It's working great, except I can't use the SPI devices.
SPI works on same hardware when running Raspbian's Buster image, after
running "dtparam spi=on" (or adding "dtparam=spi=on" to the firmware
config.txt file).
Raspbian Buster's dtparam program is not available on Debian Bookworm.
On Raspbian it comes from the libraspberrypi-bin deb, which is made from
the raspberrypi/firwmware git repo on github (the same repo that
supplies all the dtb files in /boot). dtparam and the other programs
there are provided in binary form (for armhf), not source :-(
Does anyone have any advise for me on how to enable SPI on Debian?
(In case it's not obvious, I'm a noob at dealing with device tree stuff.)
