Rob Herring 469d31745b power: reset: vexpress: Use device_get_match_data()
Use preferred device_get_match_data() instead of of_match_device() to
get the driver match data. With this, adjust the includes to explicitly
include the correct headers.

Justin Stitt 4ec7b666fb power: vexpress: fix -Wvoid-pointer-to-enum-cast warning
When building with clang 18 I see the following warning:
|       drivers/power/reset/vexpress-poweroff.c:124:10: warning: cast to smaller integer type 'enum vexpress_reset_func' from 'const void *' [-Wvoid-pointer-to-enum-cast]
|         124 |         switch ((enum vexpress_reset_func)match->data) {

This is due to the fact that `match->data` is a void* while `enum vexpress_reset_func`
has the size of an int. This leads to truncation and possible data loss.

Rob Herring 2ce8284c31 power: Explicitly include correct DT includes
The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

Miquel Raynal cba266a4f6 power: reset: at91-reset: change the power on reason prototype
It is quite uncommon to use a driver helper with parameters like *pdev
and __iomem *base. It is much cleaner and close to today's standards to
provide the per-device driver structure and then access its
internals. Let's do this with the helper which returns the power on
reason. While we change the parameters, we can as well rename the
function from at91_reset_status() to at91_reset_reason() to be more
accurate with what the helper actually does, and finally because we don't
really need the pdev argument in this helper besides for printing the
reset reason, we can move the dev_info() call into the probe.

All these modifications prepare the introduction of a sysfs entry to
access this information. This way the diff will be much smaller. Thus,
there is no intended functional change.

Uwe Kleine-König aafbf04f95 power: reset: gpio-restart: Convert to platform remove callback returning void
Returning an error code from a remove callback makes the driver core
emit a generic (and so little helpful) error message and after that the
error code is ignored and the device unbound.

As gpio_restart_remove() already emits an error message, suppressing the
generic error is no loss.

Then convert to .remove_new() which is equivalent to returning 0
unconditionally in .remove(). See commit 5c5a7680e6 ("platform:
Provide a remove callback that returns no value") for its rational.

Nick Alcock 24e4dba2a4 power: reset: remove MODULE_LICENSE in non-modules
Since commit 8b41fc4454 ("kbuild: create modules.builtin without
Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations
are used to identify modules. As a consequence, uses of the macro
in non-modules will cause modprobe to misidentify their containing
object file as a module when it is not (false positives), and modprobe
might succeed rather than failing with a suitable error message.

So remove it in the files in this commit, none of which can be built as
modules.

Nick Alcock 268f4d5b63 power: reset: mt6397: remove MODULE_LICENSE in non-modules
Since commit 8b41fc4454 ("kbuild: create modules.builtin without
Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations
are used to identify modules. As a consequence, uses of the macro
in non-modules will cause modprobe to misidentify their containing
object file as a module when it is not (false positives), and modprobe
might succeed rather than failing with a suitable error message.

So remove it in the files in this commit, none of which can be built as
modules.

Krzysztof Kozlowski ef6d10568c power: reset: qcom-pon: drop of_match_ptr for ID table
The Qualcomm SoC power-on driver is specific to ARCH_QCOM which depends
on OF thus the driver is OF-only.  It's of_device_id table is built
unconditionally, thus of_match_ptr() for ID table does not make sense.

Neil Armstrong cec3b46b8b power: reset: add Odroid Go Ultra poweroff driver
The Hardkernel Odroid Go Ultra poweroff scheme requires requesting a poweroff
to its two PMICs in order, this represents the poweroff scheme needed to complete
a clean poweroff of the system.

This implement this scheme by implementing a self registering driver to permit
using probe defer until both pmics are finally probed.
