Kumar Gala 2f9573406d drivers: adc: Convert drivers to new DT device macros 
Convert adc drivers to use new DT variants of the DEVICE APIs.
    DEVICE_AND_API_INIT -> DEVICE_DT_DEFINE
    DEVICE_GET -> DEVICE_DT_GET
    DEVICE_DECLARE -> DEVICE_DT_INST_DECLARE

etc..

Tomasz Bursztyka f1c0f2d0f9 drivers: adc: Fix device instance const qualifier loss 
It is necessary to wrap the device pointer into data.

Tomasz Bursztyka e18fcbba5a device: Const-ify all device driver instance pointers 
Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver
instance to be constant.

A coccinelle rule is used for this:

@r_const_dev_1
  disable optional_qualifier
@
@@
-struct device *
+const struct device *

@r_const_dev_2
 disable optional_qualifier
@
@@
-struct device * const
+const struct device *

Fixes #27399

Tomasz Bursztyka 98d9b01322 device: Apply driver_api/data attributes rename everywhere 
Via coccinelle:

@r_device_driver_api_and_data_1@
struct device *D;
@@
(
D->
-	driver_api
+	api

And grep/sed rules for macros:

git grep -rlz 'dev)->driver_data' |

git grep -rlz 'dev->driver_data' |

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
