This patch shold not be merged - dtbs files are not stored in the
kernel tree. We just provide this file so the code can be tested.

This overlay is suitable for testing the driver, it can be compiled with
dtc and put in the /boot/overlays/ folder then specified in config.txt
by putting the lines:

dtoverlay=		#suppress loading of default overlay for HAT
dtoverlay=sensehat	#load custom overlay

at the beginning before any other lines in config.txt

Hmm, if this is DO NOT MERGE patch due to build artifacts (in this case
dtbs), then how testing of this driver can be done with just DT source
(like other drivers)? Does providing custom overlay needed for testing
it?

Thanks.

As it's a extension board to the RaspberryPi the DTs are not included into the 
Linux kernel. Instead an overlay is build which can be loaded to the base DT via 
a special mechanism of the RPi FW.

Adding this file helps anybody who wants to test the drivers to do so without 
any hustle.
