Gerard Marull-Paretas c66f594c41 drivers: all: rv32m1: remove conditional support for pinctrl 
The rvm32m1 platform always uses pinctrl, there's no need to keep
extra macrology around pinctrl. Also updated driver's Kconfig to `select
PINCTRL`.

Tom Burdick 4c20403629 spi: callback API for asynchronous transcieve 
Adds a new spi_transcieve_cb API which enables asynchronous
SPI transactions with callback notification.

The exist spi_transcieve_async API remains and uses the new
spi_transcieve_cb API to provide a k_poll_signal notifier.

The driver API changes to provide a callback and userdata
parameter to async transcieve. All drivers in the tree
have been updated to the change.

Bartosz Bilas 05f326c96e drivers: spi_rv32m1_lpspi: initialize all cs gpios during init 
In case when we have multiple devices connected to the
one SPI interface the initial state of CS gpios after
MCU reset is floating and it might be low that prevents us from
communicating between particular devices. Fix that by
initializing all provided cs gpios and setting them as inactive.

Tomasz Bursztyka 4dcfb5531c isr: Normalize usage of device instance through ISR 
The goal of this patch is to replace the 'void *' parameter by 'struct
device *' if they use such variable or just 'const void *' on all
relevant ISRs

This will avoid not-so-nice const qualifier tweaks when device instances
will be constant.

Note that only the ISR passed to IRQ_CONNECT are of interest here.

In order to do so, the script fix_isr.py below is necessary:

Martí Bolívar 7e0eed9235 devicetree: allow access to all nodes 
Usually, we want to operate only on "available" device
nodes ("available" means "status is okay and a matching binding is
found"), but that's not true in all cases.

Sometimes we want to operate on special nodes without matching
bindings, such as those describing memory.

To handle the distinction, change various additional devicetree APIs
making it clear that they operate only on available device nodes,
adjusting gen_defines and devicetree.h implementation details
accordingly:

- emit macros for all existing nodes in gen_defines.py, regardless
  of status or matching binding
- rename DT_NUM_INST to DT_NUM_INST_STATUS_OKAY
- rename DT_NODE_HAS_COMPAT to DT_NODE_HAS_COMPAT_STATUS_OKAY
- rename DT_INST_FOREACH to DT_INST_FOREACH_STATUS_OKAY
- rename DT_ANY_INST_ON_BUS to DT_ANY_INST_ON_BUS_STATUS_OKAY
- rewrite DT_HAS_NODE_STATUS_OKAY in terms of a new DT_NODE_HAS_STATUS
- resurrect DT_HAS_NODE in the form of DT_NODE_EXISTS
- remove DT_COMPAT_ON_BUS as a public API
- use the new default_prop_types edtlib parameter
