Hi!
It would be good to get LED backlight to work in clean way for 5.6 kernel.
...
[If you have an idea what else is needed, it would be welcome; it works for me in development tree but not in tree I'd like to upstream.]
Lee, would you be willing to take "backlight: add led-backlight driver"? Would it help if I got "leds: Add managed API to get a LED from a device driver" and "leds: Add of_led_get() and led_put()" into for_next tree of the LED subsystem?
It looks like you have an open question from Tony on v10.
Is that patch orthogonal, or are there depend{ants,encies}?
Uhh looks like we messed up a bit with integration. Now droid4 LCD backlight can no longer be enabled at all manually in v5.6-rc1 without the "add led-backlight driver" patch.. Should we just merge it to fix it rather than start scrambling with other temporary hacks?
We should just merge the "add led-backlight driver". Everything should be ready for it. I'm sorry if I broke something working, I was not aware it worked at all.
Unfortunately, this is backlight code, not LED, so I can't just merge it.
I don't care if we use "default-brightness", or if we use "default-brightness-level". The binding merged says now "default-brightness", so let's go with that one. That's what other LED drivers are using too.
No opinion on that.
Best regards, Pavel
