This change make the following commands correctly detect the 4B
however there may be an issue with reading GPIO inputs on the 4B
as they are always returning zero.
The aim of this change is to be the source-equivalent of the binary
package release 2.52[1] which was the last release before upstream
development ceased.
[1] http://wiringpi.com/wiringpi-updated-to-2-52-for-the-raspberry-pi-4b/
for kernels 4.8 onwards.
Some very old stuff might break.
Additional fixes for the ISR code and some tweaks here and
there. I've removed the checks for some operations that might
fail when using the gpiomem interface - which is now the default
way of doing things - if your program segfaults, then you
may need to use sudo on it.
Added support for the ADS1115 16-bit ADC
Updated the gpio readall command to correctly with with the Compute Module
and fixed a resulting bug in wiringPi...
Also affects the Pi v2 which also uses the new Revision
encoding scheme (It was slightly bodged before) This ought
to be relatively future proof, but who knows.
Fixed a minor thing in the examples Makefile
(not that anyone bothers to use it, judging by the emails I get )-:
This makes it possible for the caller of ./build to suppress the
chown/chmod of the gpio utility.

These are not set in normal shell sessions. Honouring existing
settings allows the caller of ./build to specify alternative values.

We are going to want to introduce a real Debian source package build
system. But that needs to contain a lot of things in debian/ which
ought not to appear in the .deb made by the existing ad-hoc `./build
debian' arrangements, which we want to keep so as not to unduly
disturb existing users.
So rename the whole debian/ directory to debian-template/ and change
all references in the build system.

emacs complains about this line, because it thinks lines with just a
tab on in Makefiles are suspicious. Remove the needless tab.
No functional change.

This patch is autogenerated, with:
git-ls-files | grep Makefile | xargs perl -i~ -pe 's/^\t\@/\t\$Q /'

We want to be able to disable the many @'s in the Makefiles so
that we can see what they are doing, when things go wrong. It is
conventional to arrange for setting V=1 to have this effect.
Here we supply a formulaic stanza for either setting Q?=@ or
doing nothing. (There is sadly no standard place which is
included in all the Makefiles so this is probably best).
In this patch we do not introduce any users of Q yet. This is
because the next patch, which introduces all the users of Q, can
be generated entirely automatically. (This is also convenient in
case something needs to be rebased across it.)

the same as everyone elses.
This is an interim version which will work on both Pi v1 and v2
boards until I have a bit more time to implement the correct
stuff for v2.
Moved the extensions into wiringPi from gpio and made it more general purpose
more so that RTB and anything else can dymanically add devices
into wiringPi.
Changes to GPIO to updates for the SPI and I2C module loads
Added gpio unload for SPI and I2C.
Added a new way to setup SPI - by passing the mode in.
Support for the new Pi2 thing too
to produce a nicer 'readall' output too.
It also understands new pins 53,54,55 and 56 in wiringPiSetupPhys()
mode to represent the pins on the P5 connector on the Rev 2 Pi's
Changes to pinMode() to allow new modes SOFT_PWM and SOFT_TONE.
