The chipid macro/variable and regmap_read function call is not needed
because the TPS65219_REG_TI_DEV_ID register value is not a consistent value
across TPS65219 PMIC config versions. Reading from the DEV_ID register
without a consistent value to compare it to isn't useful. There isn't a
way to verify the match data ID is the same ID read from the DEV_ID device
register. 0xF0 isn't a DEV_ID value consistent across TPS65219 NVM
configurations.
For TPS65215, there is a consistent value in bits 5-0 of the DEV_ID
register. However, there are other error checks in place within probe()
that apply to both PMICs rather than keeping this isolated check for one
PMIC.

The ACPI ID table is defined globally without an #ifdef check for CONFIG_ACPI,
so ACPI_PTR() makes no sense here. Also note, driver depends on ACPI anyway.

REGCACHE_NONE is the default type of the cache when not provided.
Drop unneeded explicit assignment to it.
Note, it's defined to 0, and if ever be redefined, it will break

If offset end up being high enough, right hand expression in functions
like sm501_gpio_set() shifted left for that number of bits, may
not fit in int type.
Just in case, fix that by using BIT() both as an option safe from
overflow issues and to make this step look similar to other gpio
drivers.

Replace ternary (condition ? "enable" : "disable") syntax with helpers
from string_choices.h because:
1. Simple function call with one argument is easier to read. Ternary
operator has three arguments and with wrapping might lead to quite
long code.
2. Is slightly shorter thus also easier to read.
3. It brings uniformity in the text - same string.
4. Allows deduping by the linker, which results in a smaller binary
file.

Add support for STM32MP25 SoC. Use newly introduced compatible, to handle
new features.
Identification and hardware configuration registers allow to read the
timer version and capabilities (counter width, number of channels...).
So, rework the probe to avoid touching ARR register by simply read the
counter width when available. This may avoid messing with a possibly
running timer.
Also add useful bit fields to stm32-timers header file.

There are a total of 96 AFL pages and each page has 16 entries with
registers CFDGAFLIDr, CFDGAFLMr, CFDGAFLP0r, CFDGAFLP1r holding
the rule entries (r = 0..15).
Currently, RCANFD_GAFL* macros use a start variable to find AFL entries,
which is incorrect as the testing on RZ/G3E shows ch1 and ch4
gets a start value of 0 and the register contents are overwritten.
Fix this issue by using rule_entry corresponding to the channel
to find the page entries in the AFL list.

Commit 7fdaf8966aae ("can: ucan: use strscpy() to instead of strncpy()")
unintentionally introduced a one byte out of bound read on strscpy()'s
source argument (which is kind of ironic knowing that strscpy() is meant
to be a more secure alternative :)).
Let's consider below buffers:
dest[len + 1]; /* will be NUL terminated */
src[len]; /* may not be NUL terminated */
When doing:
strncpy(dest, src, len);
dest[len] = '\0';
strncpy() will read up to len bytes from src.
On the other hand:
strscpy(dest, src, len + 1);
will read up to len + 1 bytes from src, that is to say, an out of bound
read of one byte will occur on src if it is not NUL terminated. Note
that the src[len] byte is never copied, but strscpy() still needs to
read it to check whether a truncation occurred or not.
This exact pattern happened in ucan.
The root cause is that the source is not NUL terminated. Instead of
doing a copy in a local buffer, directly NUL terminate it as soon as
usb_control_msg() returns. With this, the local firmware_str[] variable
can be removed.
On top of this do a couple refactors:
- ucan_ctl_payload->raw is only used for the firmware string, so
rename it to ucan_ctl_payload->fw_str and change its type from u8 to
char.
- ucan_device_request_in() is only used to retrieve the firmware
string, so rename it to ucan_get_fw_str() and refactor it to make it
directly handle all the string termination logic.

cdns3-plat can know if power was lost across system-wide suspend.
Forward that information:
- Grab the lost_power bool from cdns_role_driver::resume(). Store it
into the power_lost field in struct xhci_plat_priv.
- xhci-plat will call xhci_resume() with that value (ORed to whether we
are in a hibernation restore).

Now that xhci_resume() exposes a power_lost boolean argument, expose

- Their own resume() callback.

Previous signature was:
int xhci_resume(struct xhci_hcd *xhci, pm_message_t msg);
Internally, it extracted two information out of the message:
- whether we are after hibernation: msg.event == PM_EVENT_RESTORE,
- whether this is an auto resume: msg.event == PM_EVENT_AUTO_RESUME.
First bulletpoint is somewhat wrong: driver wants to know if the device
did lose power, it doesn't care about hibernation per se. Knowing that,
refactor to ask upper layers the right questions: (1) "did we lose
power?" and, (2) "is this an auto resume?". Change the signature to:
int xhci_resume(struct xhci_hcd *xhci, bool power_lost,
bool is_auto_resume);
The goal is to allow some upper layers (cdns3-plat) to tell us when
power was lost after system-wise suspend.
Note that lost_power is ORed at the start of xhci_resume() to
xhci->quirks & XHCI_RESET_ON_RESUME || xhci->broken_suspend. It is
simpler to keep those checks inside of xhci_resume() instead of doing
them at each caller of xhci_resume().

At runtime_resume(), read the W1 (Wrapper Register 1) register to detect
if an hardware reset occurred. If it did, run the hardware init sequence.
This callback will be called at system-wide resume. Previously, if a
reset occurred during suspend, we would crash. The wrapper config had
not been written, leading to invalid register accesses inside cdns3.

The cdns_role_driver->resume() callback takes a second boolean argument
named `hibernated` in its implementations. This is mistaken; the only
potential caller is:
int cdns_resume(struct cdns *cdns)
{
/* ... */
if (cdns->roles[cdns->role]->resume)
cdns->roles[cdns->role]->resume(cdns, cdns_power_is_lost(cdns));
return 0;
}
The argument can be true in cases outside of return from hibernation.
Reflect the true meaning by renaming both arguments to `lost_power`.

commit 04fb365c453e ("usb: dwc3: replace %p with %pK")
When the formatting was changed from %p to %pK that was a security

Since commit ad67b74d2469 ("printk: hash addresses printed with %p")
the regular %p has been improved to avoid this issue.
On the other hand, restricted pointers ("%pK") were never meant to be used
through printk(). They can unintentionally still leak raw pointers or
acquire sleeping looks in atomic contexts.

IIO: New device support, features and cleanup for the 6.15 cycle.
The usual mixture of new drivers, support in existing drivers for new
devices, a range of features and general subsystem cleanup.
Two merges of immutable branches in here:
* SPI offload support. Culmination of a long effort to bring the ability
to offload triggered sequences of SPI operations to specific hardware,
allow high datarate acquisition over an SPI bus (if you have the right
hardware / FPGA firmware)
* GPIO set-array-helper - enables code simplification.
New device support

Cleanup and minor bug fixes
===========================
Tree wide:
- Stop using iio_device_claim_direct_scoped() and introduce sparse friendly
iio_device_claim/release_direct()
The conditional scoped cleanup has proved hard to deal with, requiring
workarounds for various compiler issues and in is rather non-intuitive
so abandon that experiment. One of the attractions of that approach was
that it made it much harder to have unbalanced claim/release bugs so
instead introduce a conditional-lock style boolean returning new pair
of functions. These are inline in the header and have __acquire and
__release calls allowing sparse to detect lack of balance. There are
occasional false positives but so far those have reflected complex code
paths that benefited from cleanup anyway.
The first set of driver conversions are in this pull request, more to
follow next cycle. Various related cleanup in drivers.
Removal of the _scoped code is completed and the definition removed.
- Use of str_enable_disable() and similar helpers.
- Don't set regmap cache to REGCACHE_NONE as that's the default anyway.
- Change some caches from RBTREE to MAPLE reflecting best practice.
- Use the new gpiod_multi_set_value_cansleep()
- Make sure to grab direct mode for some calibrations paths.
- Avoid using memcmp on structures when checking for matching channel configs.
Instead just match field by field.
dt-bindings:
- Fix up indentation inconsistencies.
gts-helper:
- Simplify building of available scale table.
adi,ad-sigma-delta
- Make sure to disable channel after calibration done.
- Add error handling in configuring channel during calibration.
adi,ad2s1201
- use a bitmap_write() rather than directly accessing underlying storage.
adi,ad3552r-hs
- Fix a wrong error message.
- Make sure to use instruction mode for configuration.
adi,ad4695
- Add a conversion to ensure exit from conversion mode.
- Use custom regmap to handle required sclk rate change.
- Fix an out of bounds array access
- Simplify oversampling ratio handling.
adi,ad4851
- Fix a sign bug.
adi,ad5791
- Fix wrong exported number of storage bits.
adi,ad7124
- Disable all channels at probe to avoid strange initial configurations.
adi,ad7173
- Rework to allow static const struct ad_sigma_delta without need
to make a copy.
adi,ad7623
- Drop a BSD license tag that the authors consider unnecessary.
adi,ad7768-1
- Fix channels sign description exposed to user space.
- Set MOSI idle state to avoid accidental device reset.
- Avoid some overkill locking.
adi,axi-dac
- Check if device interface is busy when enabling data stream.
- Add control of bus mode.

A client driver may use mhi_unprepare_from_transfer() to quiesce
incoming data during the client driver's tear down. The client driver
might also be processing data at the same time, resulting in a call to
mhi_queue_buf() which will invoke mhi_gen_tre(). If mhi_gen_tre() runs
after mhi_unprepare_from_transfer() has torn down the channel, a panic
will occur due to an invalid dereference leading to a page fault.
This occurs because mhi_gen_tre() does not verify the channel state
after locking it. Fix this by having mhi_gen_tre() confirm the channel
state is valid, or return error to avoid accessing deinitialized data.

In gfx_v12_0_cp_gfx_load_me_microcode_rs64(), gfx_v12_0_pfp_fini() is
incorrectly used to free 'me' field of 'gfx', since gfx_v12_0_pfp_fini()
can only release 'pfp' field of 'gfx'. The release function of 'me' field
should be gfx_v12_0_me_fini().

ctx->dmub_srv will de NULL if the ASIC does not support DMUB, which is
tested in dm_dmub_sw_init.
However, it will be dereferenced in dmub_hw_lock_mgr_cmd if
should_use_dmub_lock returns true.
This has been the case since dmub support has been added for PSR1.
Fix this by checking for dmub_srv in should_use_dmub_lock.
