I just want to share some details to avoid issues in the future.
This setup (with simple panel and bindings), works in the sense that the
display shows stuff, after being left on by the bootloader on the Samsung
Galaxy S5 (klte). There is no provisions for turning the screen off and
back on, backlight, or anything else.
The display is a rather advanced one, containing many features, but so far
none of them (including on/off) has been made to work. It is possible that
in the future some of those features will be figured out, and these might
very well include additional DT properties.
So would it be better to put the bindings in a separate file, ready to
grow, and for the panel - include a simple custom driver that works no
better than the simple-panel one now, but can accommodate future expansion?
