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

Many developers will be unfamiliar with UM10204 so document the rates
that are associated with the standard, fast, etc. speed names.

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
|
D->
-	driver_data
+	data

@@
(
net_if_get_device(E)->

And grep/sed rules for macros:

git grep -rlz 'dev)->driver_data' |
	xargs -0 sed -i 's/dev)->driver_data/dev)->data/g'

git grep -rlz 'dev->driver_data' |

git grep -rlz 'device->driver_data' |

71b893056f drivers: i2c: add I2C bus recovery API
Add API for recovering an I2C bus. This API can be used to recover
from situations where the I2C master and one or more I2C slaves are
out of synchronization (e.g. if the I2C master was reset in the middle
of an I2C transaction or if a noise pulse was induced on the SCL
line).

Fixes #23441.

b0b320b7dd drivers: i2c: Remove invalid syscalls
i2c_slave_register/unregister must not be syscalls since it provides
callbacks that will run in supervisor mode. Nonetheless, verification
functions were missing which means that these functions never worked
from usermode.

86bfc489f4 scripts: Replace hard-coded subsystem list with __subsystem annotations.
This change removes the hardcoded subsystem list in gen_kobject_list.py
favor of marking the relevant driver API structs with the _subsystem
sentinel.

create a shim for backward-compatibility.

No functional changes to the headers.
A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES.
