Rpi touchscreen rpi-ft5406 and overlays
User Scrumpy Jack asked me privately to open issue about:
http://lists.alpinelinux.org/alpine-devel/5375.html
I’m using a rpi with the official raspberry pi touchscreen and can get it to work. I do no get anything in /dev/input/ and the rpi-ft5406 kernel module is no loaded. The monitor itself does however work, it’s only the input. The same hardware configuration does work on raspbian. I tried to modprobe the kernel module directly and/or create an overlay manually for it, without success.
Note that this may be solved by issue 5729 (http://bugs.alpinelinux.org/issues/5729) but I haven’t figured the steps I need to be able to test the fix beyond waiting for the next release.
