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.

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.

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.

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.

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.

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.

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.

The Qualcomm SoC power-on driver is specific to ARCH_QCOM which depends

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.

644106cdb8 power: reset: ltc2952: Fix use of floating point literals
A new commit in LLVM causes an error on the use of 'long double' when
'-mno-x87' is used, which the kernel does through an alias,
'-mno-80387' (see the LLVM commit below for more details around why it
does this).

drivers/power/reset/ltc2952-poweroff.c:162:28: error: expression requires  'long double' type support, but target 'x86_64-unknown-linux-gnu' does not support it
        data->wde_interval = 300L * 1E6L;
                                  ^
drivers/power/reset/ltc2952-poweroff.c:162:21: error: expression requires  'long double' type support, but target 'x86_64-unknown-linux-gnu' does not support it
        data->wde_interval = 300L * 1E6L;
                           ^
drivers/power/reset/ltc2952-poweroff.c:163:41: error: expression requires  'long double' type support, but target 'x86_64-unknown-linux-gnu' does not support it
        data->trigger_delay = ktime_set(2, 500L*1E6L);
                                               ^
3 errors generated.

This happens due to the use of a 'long double' literal. The 'E6' part of
'1E6L' causes the literal to be a 'double' then the 'L' suffix promotes
it to 'long double'.

There is no visible reason for floating point values in this driver, as
the values are only assigned to integer types. Use NSEC_PER_MSEC, which
is the same integer value as '1E6L', to avoid changing functionality but
fix the error.

f39650de68 kernel.h: split out panic and oops helpers
kernel.h is being used as a dump for all kinds of stuff for a long time.
Here is the attempt to start cleaning it up by splitting out panic and
oops helpers.

There are several purposes of doing this:
- dropping dependency in bug.h
- dropping a loop by moving out panic_notifier.h
- unload kernel.h from something which has its own domain

At the same time convert users tree-wide to use new headers, although for
the time being include new header back to kernel.h to avoid twisted
indirected includes for existing users.

a7f79f9954 power: reset: add driver for LinkStation power off
Some Buffalo LinkStations perform the power off operation, at restart
time, depending on the state of an output pin (LED2/INTn) at the ethernet
PHY. This pin is also used to wake the machine when a WoL packet is
received by the PHY.

The driver is required by the Buffalo LinkStation LS421DE (ARM MVEBU),
and other models. Without it, the board remains forever halted if a
power off command is executed, unless the PSU is disconnected and
connected again.

Add the driver to provide the power off function and also make the WoL
feature to be available.

694b5a5d31 ARM: SoC changes for v5.8
One new platform gets added, the Realtek RTD1195, which is an older
 Cortex-a7 based relative of the RTD12xx chips that are already supported
 in arch/arm64. The platform may also be extended to support running
 32-bit kernels on those 64-bit chips for memory-constrained machines.
 
 In the Renesas shmobile platform, we gain support for "RZ/G1H" or R8A7742,
 an eight-core chip based on Cortex-A15 and Cortex-A7 cores, originally
 released in 2016 as one of the last high-end 32-bit designs.
 
 There is ongoing cleanup for the integrator, tegra, imx, and omap2
 platforms, with integrator getting very close to the goal of having
 zero code in arch/arm/, and omap2 moving more of the chip specifics
 from old board code into device tree files.
 
 The Versatile Express platform is made more modular, with built-in
 drivers now becoming loadable modules. This is part of a greater effort
 for the Android OS to have a common kernel binary for all platforms and
 any platform specific code in loadable modules.
 
 The PXA platform drops support for Compulab's pxa2xx boards that had
 rather unusual flash and PCI drivers but no known users remaining.
 All device drivers specific to those boards can now get removed as
 well.
 
 Across platforms, there is ongoing cleanup, with Geert and Rob
 revisiting some a lot of Kconfig options.
