I do not know where to ask this question, but I think that kernel 
developers could help me.

I have notebook with one special button on keyboard which is 
designed for turning ambient light sensor on and off. By default 
pressing button do nothing (I can turn ambient light sensor on/off 
via sysfs platform wmi module). Button press is reported by 
kernel input device AT Translated Set 2 keyboard and reports it 
as button "touchpad off".

Of course "touchpad off" is incorrect and I'd like to ask which 
kernel key or button from /usr/include/linux/input.h should be 
mapped for my ambient light sensor button? Is there already some? 
And what is strategy for allocating KEY_* and BTN_* numbers?

This is maintained by Dmitry, so he's the one to answer this. I am adding 
him to CC.

I guess we need patch adding

	#define KEY_ALS_TOGGLE	0x230

Thanks.
