Currently there's no LCD contrast setting, as we don't know the exact
types of the LCD and which registers to change. We just use the same
settings as the OF. The contrast problems are coming from a patch that
undervolts the LCD to 2.6V (instead of 3.0V) to prevent some awful noise
from the LCD and increase battery runtime. Even though the reason of the
noise is still not known (and I'm not experiencing it on my device), and
the battery life increase seems to be marginal on mine, people have been
in favor of this patch and it was committed.

Still I'd like to see HW keyclick and that dynamic runtime estimation
patch committed one day, the latter at least for flash-based targets.
What's blocking those? Are they candidates for 3.8?

I forgot to mention that there's also a quite noticable popping noise
when powering on the device, which is probably related. This is
apparently a bug in the driver of that Wolfson codec, we should have a
look at it after the release.
Is this also happening for other targets which use the same codec?
