Linux 5.x new release uses refined device trees and includes. Nice, but how do you patch now the bit that was in a DTS is now in a DTSI. Disabling the HDMI so I can use SPI0

Hi,

I have been told to stay indoors for 12 weeks. So I decided to learn the
AM355x, Linux and C++ and sort out some code that is well past its sell by
date.

This is for a clinical project I am doing

My board is a hacked beaglebone black, it has a real time clock, a SPIO to
drive a FT800 based LCD display, an I2C to drive some instruments. All
has worked for years but the software was really bad so I decided to make
my own, since I have time on my hands. The last programming I did was in
Pascal.

Last week I learned to use Buildroot, made a new beaglebone black Linux,
and then started to update my patches.
C++ is coming along nicely, as it doesn't completely crash your PC like it
did 25 years ago. (so far so good)

HDMI used on the regular board will interfere with my use of SPI0. Easily
done with a patch. The old blackbone source, had a source called
boneblack.dts which had the HDMI pin definitions in it. Now there is a
problem with recent blackbone device tree sources, to tidy things up they
have moved the definitions over from the DTS to a new DTSI.
The old Linux had a DTS like this:

So based on your details so far... Why are you still booting it as
"BeagleBone Black"? Your hardware more closely resembles, the
"BeagleBone Green"

Green = Black with no HDMI (plus 1 more usart enabled..)

If i was in your shoe's, i'd just start with the BeagleBone Green's
dts and add what you need..
