Peter Bigot 9dc7640ede spi-device: set CS gpio flags for all devices that had none
The generic SPI GPIO chip select support now respects devicetree flags
for signal active level.  Update all cs-gpios properties to specify
active low.

Marcin Niestroj f08ef736a0 drivers: lora: sx1276: select PA output by dts property
PA selection mainly depends on board design. So it looks like
device-tree is a better mechanism than Kconfig in this case. Use string
property with two possible values: "rfo" and "pa-boost".

Martí Bolívar 6e8775ff84 devicetree: remove DT_HAS_NODE_STATUS_OKAY
Several reviewers agreed that DT_HAS_NODE_STATUS_OKAY(...) was an
undesirable API for the following reasons:

- it's inconsistent with the rest of the DT_NODE_HAS_FOO names
- DT_NODE_HAS_FOO_BAR_BAZ(node) was agreed upon as a shorthand
  for macros which are equivalent to
  DT_NODE_HAS_FOO(node) && DT_NODE_HAS_BAR(node) &&
- DT_NODE_HAS_BAZ(node), and DT_HAS_NODE_STATUS_OKAY is an odd duck
- DT_NODE_HAS_STATUS(..., okay) was viewed as more readable anyway
- it is seen as a somewhat aesthetically challenged name

Replace all users with DT_NODE_HAS_STATUS(..., okay), which is
semantically equivalent.

This is mostly done with sed, but a few remaining cases were done by
hand, along with whitespace, docs, and comment changes. These special
cases include the Nordic SOC static assert files.

Ulf Magnusson a42a42cd5a kconfig: Replace defconfig singe-symbol 'if's with 'depends on'
Same deal as in commit eddd98f ("kconfig: Replace some single-symbol
'if's with 'depends on'"), for all symbols defined within defconfig
files. See that commit for an explanation.

Maybe 'if's were used originally to mirror the 'if's in the main Kconfig
files, and then it got copied around by people assuming 'if' must work
differently from 'depends on'. It doesn't match in every spot at least.
Better to keep it simple and just consistently use 'depends on' when
it's a single symbol/choice I think. Helps reinforce that 'if' isn't
magic too.

Verified by printing all Kconfig menu nodes (symbols, choices, menus,
etc.) before and after the change and diffing (should show no
difference).

Ulf Magnusson c5839f834b kconfig: Remove assignments to CONFIG_<arch> syms and hide them
All board defconfig files currently set the architecture in addition to
the board and the SoC, by setting e.g. CONFIG_ARM=y. This spams up
defconfig files.

CONFIG_<arch> symbols currently being set in configuration files also
means that they are configurable (can be changed in menuconfig and in
configuration files), even though changing the architecture won't work,
since other things get set from -DBOARD=<board>. Many boards also allow
changing the architecture symbols independently from the SoC symbols,
which doesn't make sense.

Get rid of all assignments to CONFIG_<arch> symbols and clean up the
relationships between symbols and the configuration interface, like
this:

1. Remove the choice with the CONFIG_<arch> symbols in arch/Kconfig and
   turn the CONFIG_<arch> symbols into invisible
   (promptless/nonconfigurable) symbols instead.

   Getting rid of the choice allows the symbols to be 'select'ed (choice
   symbols don't support 'select').

2. Select the right CONFIG_<arch> symbol from the SOC_SERIES_* symbols.
   This makes sense since you know the architecture if you know the SoC.

   Put the select on the SOC_* symbol instead for boards that don't have
   a SOC_SERIES_*.

3. Remove all assignments to CONFIG_<arch> symbols. The assignments
   would generate errors now, since the symbols are promptless.

The change was done by grepping for assignments to CONFIG_<arch>
symbols, finding the SOC_SERIES_* (or SOC_*) symbol being set in the
same defconfig file, and putting a 'select' on it instead.

See
https://github.com/ulfalizer/zephyr/commits/hide-arch-syms-unsquashed
for a split-up version of this commit, which will make it easier to see
how stuff was done. This needs to go in as one commit though.

This change is safer than it might seem re. outstanding PRs, because any
assignment to CONFIG_<arch> symbols generates an error now, making
outdated stuff easy to catch.

dts pinctrl definitions were pushed in tree without the code
available to deal with it. They have been kept waiting for the
code, but this is taking much more time than initially thought.

So in current zephyr tree, for all STM32 boards, we have pinmux.c
file which is used to configure pins and these files that are
basically no-op. This situation is creating a lot of confusion
especially to new comers, and create useless maintenance effort.

Remove these files for now.
When zephyr will ready to use them, this commit could be reverted.
