Marcus started a project in 2016 to bring the pi433 alive. One project
was funded successfully but the second not. So only a few pi433 got sold
to early adaptors during this time that ended late 2017. There is a
simple user space program available for a demo with the pi433 but that
does not use this driver.
The driver is unused since 2018. No description or user space application
to use it can be found. To bring it alive the device tree needs to be
adjusted manually.
The last patch reviewed by Marcus was in June 2018, last patch tested
was in July 2017.
No response since 27. March 2024 regarding the removal of the driver.
Remove unused driver because of the above named reasons.

The reason why rf69_get_flag() existed was to provide a high-level way
to obtain values out of 1 (of 2) flags registers using bit masking. The
idea was to map the possible flag values found in the data sheet like
shown in page 70 of the RFM69HCW datasheet.
However, due to the fact that enums values in C must be unique, there
was a naming conflict on 'fifo_not_empty' which is used by the
tx_start_condition enum. So the author decided to create a 'fifo_empty'
one which would negate the value that comes from the flag register as
the solution to that conflict (which is very confusing).
this patch removes rf69_get_flag function which subsequently solves the
enum redeclaration problem so kernel developers can follow the data
sheet more easily.

This adds debugfs interface that can be used for debugging possible
hardware/software issues.
It currently exposes the following debugfs entries for each SPI device
probed:
/sys/kernel/debug/pi433/<DEVICE>/regs
...
The 'regs' file contains all rf69 uC registers values that are useful
for troubleshooting misconfigurations between 2 devices. It contains one
register per line so it should be easy to use normal filtering tools to
find the registers of interest if needed.

As a convention for the pi433 driver, all routines that deals with the
rf69 chip are defined in the rf69.c file. There was an exception to the
rule in which the uC version verification was being done directly
elsewhere. While at it, the Version Register hardcoded value was
replaced with a pre-existing constant in the driver.
This patch adds rf69_get_version function to rf69.c

The SPDX identifier is a legally binding shorthand,
which can be used instead of the full boiler plate text.
All source and header files have SPDX identifiers.
Remove the GPL boiler plate text to reduce file size.
