Tweak the name of the idle-states subnodes so that they follow the
binding pattern, getting rid of dtbs_check warnings.
Only the usage of "-" in the name was necessary, but "off" was also
exchanged for "sleep" since that seems to be a more common wording in
other dts files.

Commit 6727ad9e20 ("nmi_backtrace: generate one-line reports for idle cpus")
introduced a new text section called cpuidle; with that, we have a mechanism
to add idling functions in such section and skip them from nmi_backtrace
output, since they're useless and potentially flooding for such report.
Happens that inlining might cause some real idle functions to end-up
outside of such section; this is currently the case of ACPI processor_idle
driver; the functions acpi_idle_enter_* do inline acpi_idle_do_entry(),
hence they stay out of the cpuidle section.
Fix that by marking such functions to also live in the cpuidle section.

Error: External symbol 'memset' referenced from prom_init.c
make[2]: *** [arch/powerpc/kernel/Makefile:204: arch/powerpc/kernel/prom_init_check] Error 1
The allmodconfig build enables KASAN, so all calls to memset in
prom_init should be converted to __memset by the #ifdefs in
asm/string.h, because prom_init must use the non-KASAN instrumented
versions.
The build failure happens because there's a call to memset that hasn't
been caught by the pre-processor and converted to __memset. Typically
that's because it's a memset generated by the compiler itself, and that
is the case here.
With GCC 12, allmodconfig enables CONFIG_INIT_STACK_ALL_PATTERN, which
causes the compiler to emit memset calls to initialise on-stack
variables with a pattern.
Because prom_init is non-user-facing boot-time only code, as a
workaround just disable stack variable initialisation to unbreak the
build.

It was observed that by allowing pinctrl_amd to be loaded
later in the boot process that interrupts sent to the GPIO
controller early in the boot are not serviced. The kernel treats
these as a spurious IRQ and disables the IRQ.
This problem was exacerbated because it happened on a system with
an encrypted partition so the kernel object was not accesssible for
an extended period of time while waiting for a passphrase.
To avoid this situation from occurring, stop allowing pinctrl-amd
from being built as a module and instead require it to be built-in
or disabled.

[ Upstream commit 8386c414e2 ]
syzbot is reporting hung task at misc_open() [1], for there is a race
window of AB-BA deadlock which involves probe_count variable. Currently
wait_for_device_probe() from snapshot_open() from misc_open() can sleep
forever with misc_mtx held if probe_count cannot become 0.
When a device is probed by hub_event() work function, probe_count is
incremented before the probe function starts, and probe_count is
decremented after the probe function completed.
There are three cases that can prevent probe_count from dropping to 0.
(a) A device being probed stopped responding (i.e. broken/malicious
hardware).
(b) A process emulating a USB device using /dev/raw-gadget interface
stopped responding for some reason.
(c) New device probe requests keeps coming in before existing device
probe requests complete.
The phenomenon syzbot is reporting is (b). A process which is holding
system_transition_mutex and misc_mtx is waiting for probe_count to become
0 inside wait_for_device_probe(), but the probe function which is called
from hub_event() work function is waiting for the processes which are
blocked at mutex_lock(&misc_mtx) to respond via /dev/raw-gadget interface.
This patch mitigates (b) by deferring wait_for_device_probe() from
snapshot_open() to snapshot_write() and snapshot_ioctl(). Please note that
the possibility of (b) remains as long as any thread which is emulating a
USB device via /dev/raw-gadget interface can be blocked by uninterruptible
blocking operations (e.g. mutex_lock()).
Please also note that (a) and (c) are not addressed. Regarding (c), we
should change the code to wait for only one device which contains the
image for resuming from hibernation. I don't know how to address (a), for
use of timeout for wait_for_device_probe() might result in loss of user
data in the image. Maybe we should require the userland to wait for the
image device before opening /dev/snapshot interface.

[ Upstream commit 7d4edccc9b ]
Taking a lock at the beginning of .remove() doesn't prevent new readers.
With the existing approach it can happen, that a read occurs just when
the lock was taken blocking the reader until the lock is released at the
end of the remove callback which then accessed *data that is already
freed then.
To actually fix this problem the hwmon core needs some adaption. Until
this is implemented take the optimistic approach of assuming that all
readers are gone after hwmon_device_unregister() and
sysfs_remove_group() as most other drivers do. (And once the core
implements that, taking the lock would deadlock.)
So drop the lock, move the reset to after device unregistration to keep
the device in a workable state until it's deregistered. Also add a error
message in case the reset fails and return 0 anyhow. (Returning an error
code, doesn't stop the platform device unregistration and only results
in a little helpful error message before the devm cleanup handlers are
called.)

It seems that these quirks are no longer necessary since
commit 69b957c26b ("ACPI: EC: Fix possible issues related to EC
initialization order"), which has fixed this in a generic manner.
There are 3 commits adding DMI entries with this quirk (adding multiple
DMI entries per commit). 2/3 commits are from before the generic fix.
Which leaves commit 6306f04319 ("ACPI: EC: Make more Asus laptops
use ECDT _GPE"), which was committed way after the generic fix.
But this was just due to slow upstreaming of it. This commit stems
from Endless from 15 Aug 2017 (committed upstream 20 May 2021):
https://github.com/endlessm/linux/pull/288
The current code should work fine without this:
1. The EC_FLAGS_IGNORE_DSDT_GPE flag is only checked in ec_parse_device(),
like this:
if (boot_ec && boot_ec_is_ecdt && EC_FLAGS_IGNORE_DSDT_GPE) {
ec->gpe = boot_ec->gpe;
} else {
/* parse GPE */
}
2. ec_parse_device() is only called from acpi_ec_add() and
acpi_ec_dsdt_probe()
3. acpi_ec_dsdt_probe() starts with:
if (boot_ec)
return;
so it only calls ec_parse_device() when boot_ec == NULL, meaning that
the quirk never triggers for this call. So only the call in
acpi_ec_add() matters.
4. acpi_ec_add() does the following after the ec_parse_device() call:
if (boot_ec && ec->command_addr == boot_ec->command_addr &&
ec->data_addr == boot_ec->data_addr &&
!EC_FLAGS_TRUST_DSDT_GPE) {
/*
* Trust PNP0C09 namespace location rather than
* ECDT ID. But trust ECDT GPE rather than _GPE
* because of ASUS quirks, so do not change
* boot_ec->gpe to ec->gpe.
*/
boot_ec->handle = ec->handle;
acpi_handle_debug(ec->handle, "duplicated.\n");
acpi_ec_free(ec);
ec = boot_ec;
}
The quirk only matters if boot_ec != NULL and EC_FLAGS_TRUST_DSDT_GPE
is never set at the same time as EC_FLAGS_IGNORE_DSDT_GPE.
That means that if the addresses match we always enter this if block and
then only the ec->handle part of the data stored in ec by ec_parse_device()
is used and the rest is thrown away, after which ec is made to point
to boot_ec, at which point ec->gpe == boot_ec->gpe, so the same result
as with the quirk set, independent of the value of the quirk.
Also note the comment in this block which indicates that the gpe result
from ec_parse_device() is deliberately not taken to deal with buggy
Asus laptops and all DMI quirks setting EC_FLAGS_IGNORE_DSDT_GPE are for
Asus laptops.
Based on the above I believe that unless on some quirked laptops
the ECDT and DSDT EC addresses do not match we can drop the quirk.
I've checked dmesg output to ensure the ECDT and DSDT EC addresses match
for quirked models using https://linux-hardware.org hw-probe reports.
I've been able to confirm that the addresses match for the following
models this way: GL702VMK, X505BA, X505BP, X550VXK, X580VD.
Whereas for the following models I could find any dmesg output:
FX502VD, FX502VE, X542BA, X542BP.
Note the models without dmesg all were submitted in patches with a batch
of models and other models from the same batch checkout ok.
This, combined with that all the code adding the quirks was written before
the generic fix makes me believe that it is safe to remove this quirk now.

There's no reason the timer needs > 32-bits of address or size.
Since we using 32-bit size, we need to define ranges properly.

[ Upstream commit 935327a735 ]
Meraki MR26 is an EOL wireless access point featuring a
PoE ethernet port and two dual-band 3x3 MIMO 802.11n
radios and 1x1 dual-band WIFI dedicated to scanning.
Thank you Amir for the unit and PSU.
Hardware info:
SOC : Broadcom BCM53015A1KFEBG (dual-core Cortex-A9 CPU at 800 MHz)
RAM : SK Hynix Inc. H5TQ1G63EFR, 1 GBit DDR3 SDRAM = 128 MiB
NAND : Spansion S34ML01G100TF100, 1 GBit SLC NAND Flash = 128 MiB
ETH : 1 GBit Ethernet Port - PoE (TPS23754 PoE Interface)
WIFI0 : Broadcom BCM43431KMLG, BCM43431 802.11 abgn (3x3:3)
WIFI1 : Broadcom BCM43431KMLG, BCM43431 802.11 abgn (3x3:3)
WIFI2 : Broadcom BCM43428 "Air Marshal" 802.11 abgn (1x1:1)
BUTTON: One reset key behind a small hole next to the Ethernet Port
LEDS : One amber (fault), one white (indicator) LED, separate RGB-LED
MISC : Atmel AT24C64 8KiB EEPROM i2c
: Ti INA219 26V, 12-bit, i2c output current/voltage/power monitor
SERIAL:
WARNING: The serial port needs a TTL/RS-232 3V3 level converter!
The Serial setting is 115200-8-N-1. The board has a populated
right angle 1x4 0.1" pinheader.
The pinout is: VCC (next to J3, has the pin 1 indicator), RX, TX, GND.
Odd stuff:
- uboot does not support lzma compression, but gzip'd uImage/DTB work.
- uboot claims to support FIT, but fails to pass the DTB to the kernel.
Appending the dtb after the kernel image works.
- RGB-controller is supported through an external userspace program.
- The ubi partition contains a "board-config" volume. It stores the
MAC Address (0x66 in binary) and Serial No. (0x7c alpha-numerical).
- SoC's temperature sensor always reports that it is on fire.
This causes the system to immediately shutdown! Looking at reported
"418 degree Celsius" suggests that this sensor is not working.
WIFI:
b43 is able to initialize all three WIFIs @ 802.11bg.
