I'm sorry, this is not your fault, but this ads7846_device thing is an
absolute abomination. Why is RaspberryPi *THE* platform propagating all
the worst possible abominations? Why is it *THE* platform doing all the
non-standard stuff? Why is it so crappy.
People, please read this: if you want to learn embedded Linux, don't
buy Raspberry Pi. It is the worst platform ever in terms of embedded
Linux development best practices. Ever.
Do yourself a favor, and buy properly supported stuff: the Atmel
Xplained comes to mind, the BeagleBone Black as well of course.
Sorry, but this ads7846_device is just pure crap. The alternatives you
mentioned are the only good solutions: change your board file if you're
using an old style ARM kernel, or change your Device Tree if you're
using a new style ARM kernel.
I don't know what the policy of Buildroot should be about accepting
crap, but on my side, I will not add such a package to Buildroot.
Again: don't take this personally, this is absolutely not against you.
Just me being fed up with Raspberry Pi crap.
Best regards,
Thomas
