I'm sorry about that. I checked gmane and the v1 never made it to the
davinci-linux list. I think it was because of my (mis)use of git
send-email. Version 2 made it to the list so I've now found the magic
incantation.
The reason we should at least select INPUT_POLLDEV as a default option
is: when it is not set the gpio-keys instances registered by the
da850-evm board setup routine will fail probe() of the gpio-keys
driver since it will not have polled-input support enabled.
By setting INPUT_POLLDEV default for the da850-evm users will get
functioning pushbuttons and switches with the default config but they
will be able to disable INPUT_POLLDEV or gpio-keys drivers in their
defconfig at their convenience.

Oops. That's my fault. The internal reviewers also reminded me to
remove these before sending. Sorry for the noise/ I will remove this
block in _this_ patch in the re-spin.
