399c04ce5a scripts/dts: Remove unused variables and imports
Discovered with pylint3.

Use the placeholder name '_' for unproblematic unused variables. It's
what I'm used to, and pylint knows not to flag it.

Also improve the naming a bit in devicetree.py. If a key/value is known
to be a specific thing (like a node), then it's helpful to call it that
instead of something generic like "value".

It's not obligatory for Python classes to have an __init__().

0a3f00ad7c scripts/dts: Rename get_node_label() to node_label()
Just returns a value, with no side effects.

f5b17d4138 scripts/dts: Call /foo/bar a "path" instead of an "address"
It's confusing that "address" is often used within the same function to
refer to both node paths and e.g. address cells.

Make things easier to understand by calling /foo/bar a path instead.

35ecc78cdf scripts/dts/extract: Generate unique defines based on compat & instance
Add support to generate defines of the form
DT_<COMPAT>_<INSTANCE>_<PROP>.  The idea is that we can utilize this in
drivers to remove the need for dts_fixup.h.  The <INSTANCE> value is
determined by the script and starts at 0 and counts up for each instance
of a given <COMPAT>.

f34a99532a scripts: extract_dts_includes: Pass node address to get_binding
Change get_binding to take the node address instead of the
compatiable.  This is in prep for having get_binding be able to look
at the parent of the node and determine which bus specific binding to
utilize (for cases like sensors that support both I2C & SPI).

112b0f5eff scripts: extract_dts_includes: Add accessor function to access binding
Add accessor functions get_binding and get_binding_compats to
encapsulate access to binding database info.  Cleanup all direct access
to binding info and replace with calls to get_binding() and
get_binding_compats()

35afcc9c12 scripts: extract_dts_includes: remove passing yaml param to functions
Various functions like add_prop_aliases, extract_single_prop,
extract_single, reg.extract, compatible.extract, default.extract, and
flash.extract don't use the yaml argument that is passed to them.
Remove passing the argument, this is the first step in making access to
the yaml node information go through an accessor function.

a7c430f36f scripts: dts: Use DT_ prefix in generated labels
Almost all labels generated by the extracting script are now prefixed
with DT_. The only exceptions are:
- stuff with 'base_label' specified in yaml bindings
- items specified by 'regs_config' and 'name_config' dictionaries
  in globals.py module
- FLASH related labels generated by flash.extract() called separately
  from generate_node_definitions(), e.g. FLASH_WRITE_BLOCK_SIZE -
  these are used directly, not through fixups, from existing code
  so I didn't want to touch them now

Labels generated for aliases are additionally prefixed with information
from the 'compatible' property, e.g. DT_GPIO_LEDS_LED0_* is generated
instead of LED0_*. To provide backward compatibility for code that uses
LEDx_* and SWx_* labels in their previous forms, a command line option
named 'old-alias-names' is added to the extraction script. This option
causes that the labels for aliases are generated in both old and new
forms. Currently this option is always enabled in dts.cmake.

f6a30ff070 dts/extract_dts_includes.py: refactor get_node_label_string
We can replace the method get_node_label_string in DTDirective with the
global function get_node_label.  This way we have a single place that
labels for defines are being generated.

Parameter 'names' is provided as argument of several property
extract functions. Thought it is actually used only once.
Remove when not needed.

1642c45717 scripts: dts: extract: clock.py fix node alias name
A node alias name should be applied to the all property names.

Before this patch, the alias name is applied erroneously
just for CLOCK_CONTROLLER, skipping the CLOCK_BITS and CLOCK_BUS
property names.
