+  The MAX6639 is a 2-channel temperature monitor with dual, automatic, PWM
+  fan-speed controller.  It monitors its own temperature and one external
+  diode-connected transistor or the temperatures of two external diode-connected
+  transistors, typically available in CPUs, FPGAs, or GPUs.

Subject: drop second/last, redundant "binding for". The "dt-bindings"
prefix is already stating that these are bindings.

Drop blank line

This is v9. Where is the changelog? Where is previous authorship? At
least some parts of it? Why this has less properties than old one? Why
this has more mistakes than the old one? Go to previous patch... or fix
everything which was already fixed.

Best regards,
Krzysztof

This patch is to add basic dt support only hence no additional properties.

This patch is intended to add dt support for the max6639 driver, and I 
did not take it from previous patches. As this is a basic dt binding, it 
has fewer properties compared to the old one.

I have used v8 as a reference for this patch, and I will review it again 
to make sure I have not missed anything. Will ensure to fix them in the 
next patch.

Although I cannot go back to the previous patch, I will address and fix 
any issues in this patchset.
