Well, simply forgotten :)

I have tested a little in the background on GTA04A4 and GTA04A5 with letux-5.1-rc3
and have not observed problems so far.

So let's enable it in letux-5.1-rc and letux-5.0-next. 4.20 and 4.19 do not have
the underlying patch.

Linux letux 5.1.0-rc3-letux+ #3668 SMP PREEMPT Sat Apr 6 18:53:28 CEST 2019 armv7l GNU/Linux
root at letux:~# gunzip </proc/config.gz | fgrep -i offmode
CONFIG_OMAP3_PM_OFFMODE=y

BR and thanks,
Nikolaus
