Really, so nowwhere is static? Everything must be global? Sorry, but
this is not even kernel related, but basic C programming. All your
functions *MUST* be static.

What the crap is this? Isn't gpio_request() some crazy old legacy code?
Open some new driver and look how GPIO is handled there. You must use
gpio descriptors.

Drop "E" whatever it is and use standard Linux functions: dev_err().
This applies everywhere.
Abyway, request of GPIO does not happen in power config but in probe.

error? Open existing driver and look how it is named there. Usually ret

This is not a Linux kernel code style. Open existing driver and look how
it is done there.

This is very, very poor code with hundreds of style issues. This just
does not look like ready for sending upstream. Plus you stuffed here
many undocumented properties, so you bypass the bindings review.
