Ah, the 4th patch is now found to be only needed because of the
initialization sequence error found by Sashiko in the 3rd one.

With the initialization sequence fixed by comparing to other panels,
this patch would be unnecessary and panel sleep mode is now safe w/o
software reset.

Should I send a revert when sending the sequence fix?

Thanks,
