Hi Stephane,

+static int emulate_touchscreen = 1;
+module_param_named(emulate_touchscreen, emulate_touchscreen, int,  
0600);
+MODULE_PARM_DESC(emulate_touchscreen,

I thought we agreed that this option is unnecessary.

Well, actually I was unsure what the conclusion of your discussion  
was. I decided that I would send this patch as is to see what  
happens :-)

Here are our options:
  1) mix touchscreen emulation and multitouch at all times
  2) only activate touchscreen emulation when requested (module  
parameter, or something else)
  3) have separate input nodes
  4) kill the touchscreen emulation code, let the higher layers do it  
if necessary

I personally would rule out option 4. The others are OK to me. Your  
thoughts?

St.

PS: since yesterday, I have a working firmware on my NTrig panel. It  
will be interesting to see what happens with a device that  
distinguishes fingers and stylus but does not provide finger  
tracking. Maybe it will give a new light on this.
