ok fc11 ec@ 2 invert and fc11 ec!
Thanks, verified that it works. This means we could add that to the
kernel as a feature if we could justify the effort ... but there is a
risk that a later version of EC firmware may reset the "output enable"
bits.
That risk is fairly low. I think the risk is higher that that the GPIO
pin assignments might change, but even that risk is reasonably low now
that the board design is starting to "freeze".
This solves one half of the puzzle ... leaving the wireless LED on.
Does anyone know if the wireless kernel module manages that, or if it is
tied to the wireless chips? What about the battery LED?
The battery LED can be handled with a similar trick, as it it driven in
a similar fashion, by two other GPIO pins, one for green and one for red.
The wireless LEDs are driven directly from the wireless module. I
recall seeing some commands for controlling them in the wireless
firmware API, but don't know the details.
