Staging/IIO driver patches for 5.9-rc1
Here is the large set of Staging and IIO driver patches for 5.9-rc1. Lots of churn here, but overall the size increase in lines added is small, while adding a load of new IIO drivers. Major things in here: - lots and lots of IIO new drivers and frameworks added - IIO driver fixes and updates - lots of tiny coding style cleanups for staging drivers - vc04_services major reworks and cleanups We had 3 set of drivers move out of staging in this round as well: - wilc1000 wireless driver moved out of staging - speakup moved out of staging - most USB driver moved out of staging Full details are in the shortlog. All of these have been in linux-next with no reported issues. The last few changes here were to resolve reported linux-next issues, and they seem to have resolved the problems.

Description:

Contaminants build-up in the measurement chamber or optical
|

elements deterioration leads to sensor drift.
|
||||
|

One can compensate for sensor drift by using forced
|

recalibration (frc). This is useful in case there's known
|
||||
co2 reference available nearby the sensor.
|
||||
|
||||
Picking value from the range [400 1 2000] and writing it to the
|
||||
sensor will set frc.
|
||||
|
||||
Upon reading current frc value is returned. Note that after
|

power cycling default value (i.e 400) is returned even though
|

internally sensor had recalibrated itself.

Speakup is a kernel based screen review package for the linux operating
|
||||
system. It allows blind users to interact with applications on the
|
||||
linux console by means of synthetic speech.
|
||||
|
||||
Currently, speakup has one issue we know of.
|
||||
|
||||
It seems to only happen on SMP systems. It seems that text in the output buffer
|
||||
gets garbled because a lock is not set. This bug happens regularly, but no one
|
||||
has been able to find a situation which produces it consistently.
|
||||
|
||||
Patches, suggestions, corrections, etc, are definitely welcome.
|
||||
|
||||
