The situation is quite similar to #858975 where I asked for enabling
CONFIG_W1_MASTER_GPIO. In both cases, a device tree needs to supply the
information.

I am actually using such a system and my present method is to update
Debian's device tree after installing kernels. It's not pretty, but good
enough for me.

I fully agree here and second the request for CONFIG_DHT11. Enabling
this driver is another piece to shrinking the gap with Raspbian and
making Debian a viable alternative on these devices.

If you disagree here, you should revert #858975 for consistency's sake.
