Add some missing hid usages from consumer page, add
display brightness control usages from approved hid usage
table request HUTTR41:
http://www.usb.org/developers/hidpage/HUTRR41.pdf
and add voice command usage from approved request HUTTR45:
http://www.usb.org/developers/hidpage/Voice_Command_Usage.pdf

Hi all,

with this patch we add some missing hid usages to the hid system.
Those missing hid usages are already used by some Logitech
products as well as some future ones.

(Note: checkpatch.pl shows some errors but I didn't want to
break the current code style in hid-input.c)

Best regards,

Olivier

Thanks for the patch, Olivier. All looking good to me, but for the input.h 
additions, I'd like to get Ack from Dmitry, hence CCing him.

Dmitry, ok to take this through my tree with your ack?

Thanks.

Hi Dmitry,

by any chance did you take a look on this commit we submitted?

What is it supposed to do exactly? Show OSD for brightness?

We already have KEY_DISPLAYTOGGLE, isn't this the same?

Thanks.

No, it's a linear control usage to (HUTTR41) "Sets brightness to a
value between logical min and max.". I'm changing the comment to /*
Set Brightness */.

I agree, they are the same and we should alias it to
KEY_DISPLAYTOGGLE. I'm sending a v2 patch.

Best regards,

Olivier

Then it does not make sense to expose it as a key - how system should
respond to such event? Pick a random value?

If we really need to support this we need ABS_BRIGHTNESS, like we have
ABS_VOLUME.

Thanks.

Yes, I also noticed that after sending v2. We would also need to
pass/use the linear control value.

This is not absolutely needed and the other display brightness usages
are more important (like increment, decrement or toggle). I'm sending
a new v3 without this usage.
