[RFC][PATCH] Input: define keys for WWAN and SES

["Rafał Miłecki" <zajec5@gmail.com>]

This is just a RFC, so be nice to this "patch", please ;)

My goal is to add support for buttons on bcm47xx arch. However after
analyzing existing database of devices I realized I don't know what code
I should assign to some buttons.

First of all, older routers often have a "SES" button. SES stands for
SecureEasySetup and is Broadcom's proprietary protocol which was later
replaced with WPS (Wi-Fi Protected Setup).
Btw. WPS appeared to be broken because it's easy to attack it with
brutal-force method. I'm not sure if any distribution have any interest
in using that buttons, but it still would be nice to have support for
them in kernel. One option is to add KEY_SES for this purpose.
Is this the right way? It's similar to the KEY_WPS_BUTTON, but I wanted
to somehow distinct them. Is there any other option? Should I use
KEY_UNKNOWN or BTN_MISC or BTN_n?

Another thing is WWAN key. Some routers support mobile networks (for
example Linksys 54G3G) and they may have button for enabling/disabling
such connection. We already have KEY_BLUETOOTH, KEY_WLAN and KEY_UWB,
but nothing for WWAN device control. I guess in future KEY_WWAN could
be also supported in rfkill by mapping it to the RFKILL_TYPE_WWAN.

What do you think about this?
