All the MFD components are gone from the header meanwhile. Only the MMC
relevant data is left which makes it a platform_data for the MMC

bnxt doesn't check if a ring is used by RSS contexts when reducing
ring count. Core performs a similar check for the drivers for
the main context, but core doesn't know about additional contexts,
so it can't validate them. bnxt_fill_hw_rss_tbl_p5() uses ring
id to index bp->rx_ring[], which without the check may end up
being out of bounds.
BUG: KASAN: slab-out-of-bounds in __bnxt_hwrm_vnic_set_rss+0xb79/0xe40

Not all registers in PMU_ALIVE block support atomic set/clear operations.
GS101_SYSIP_DAT0 and GS101_SYSTEM_CONFIGURATION registers are two regs
where attempting atomic access fails.
As documentation on exactly which registers support atomic operations is
not forthcoming. We default to atomic access, unless the register is
explicitly added to the tensor_is_atomic() function. Update the comment
to reflect this as well.

Qualcomm driver updates for v6.11
Support for Shared Memory (shm) Bridge is added, which provides a
stricter interface for handling of buffers passed to TrustZone.
The X1Elite platform is added to uefisecapp allow list, to instantiate
the efivars implementation.
A new in-kernel implementation of the pd-mapper (or servreg) service is
introduced, to replace the userspace dependency for USB Type-C and
battery management.
Support for sharing interrupts across multiple bwmon instances is added,
and a refcount imbalance issue is corrected.
The LLCC support for recent platforms is corrected, and SA8775P support
is added.
A new interface is added to SMEM, to expose "feature codes". One example
of the usecase for this is to indicate to the GPU driver which
frequencies are available on the given device.
The interrupt consumer and provider side of SMP2P is updated to provide
more useful names in interrupt stats.
Support for using the mailbox binding and driver for outgoing IPC
interrupt in the SMSM driver is introduced.
socinfo driver learns about SDM670 and IPQ5321, as well as get some
updates to the X1E PMICs.
pmic_glink is bumped to now support managing 3 USB Type-C ports.

The GPIO subsystem used to have a serious problem with undefined behavior
and use-after-free bugs on hot-unplug of GPIO chips. This can be
considered a corner-case by some as most GPIO controllers are enabled
early in the boot process and live until the system goes down but most
GPIO drivers do allow unbind over sysfs, many are loadable modules that
can be (force) unloaded and there are also GPIO devices that can be
dynamically detached, for instance CP2112 which is a USB GPIO expender.
Bugs can be triggered both from user-space as well as by in-kernel users.
We have the means of testing it from user-space via the character device
but the issues manifest themselves differently in the kernel.
This is a proposition of adding a new virtual driver - a configurable
GPIO consumer that can be configured over configfs (similarly to
gpio-sim) or described on the device-tree.
This driver is aimed as a helper in spotting any regressions in
hot-unplug handling in GPIOLIB.

If we fail to read a logical block size in virtblk_read_limits() ->
virtio_cread_feature(), then we default to what is in
lim->logical_block_size, but that would be 0.
We can deal with lim->logical_block_size = 0 later in the
blk_mq_alloc_disk(), but the code in virtblk_read_limits() needs a proper
default, so give a default of SECTOR_SIZE.

sa8775p-ride-r3
On sa8775p-ride-r3 the RX clocks from the AQR115C PHY are not available at
the time of the DMA reset. We can however extract the RX clock from the
internal SERDES block. Once the link is up, we can revert to the
previous state.
The AQR115C PHY doesn't support in-band signalling so we can count on
getting the link up notification and safely reuse existing callbacks
which are already used by another HW quirk workaround which enables the
functional clock to avoid a DMA reset due to timeout.
Only enable loopback on revision 3 of the board - check the phy_mode to
make sure.

Use the dev_err_probe() helper to log the errors on every error path in
the probe function and its sub-functions. This includes
* adding error messages where there was none
* converting over dev_err/dev_warn
* removing the top-level error message after mtk_cpu_dvfs_info_init() is
called, since every error path inside that function already logs the
error reason. This gets rid of the misleading error message when probe
is deferred:

Some of LoongArch processors (Loongson-3 series) support DVFS, their
IOCSR.FEATURES has IOCSRF_FREQSCALE set. And they has a micro-core in
the package called SMC (System Management Controller), which can be
used to detect temperature, control fans, scale frequency and voltage,
etc.
The Loongson-3 CPUFreq driver is very simple now, it communicate with
SMC, get DVFS info, set target frequency from CPUFreq core, and so on.
There is a command list to interact with SMC, widely-used commands in
the CPUFreq driver include:
CMD_GET_VERSION: Get SMC firmware version.
CMD_GET_FEATURE: Get enabled SMC features.
CMD_SET_FEATURE: Enable SMC features, such as basic DVFS, BOOST.
CMD_GET_FREQ_LEVEL_NUM: Get the number of all frequency levels.
CMD_GET_FREQ_BOOST_LEVEL: Get the first boost frequency level.
CMD_GET_FREQ_LEVEL_INFO: Get the detail info of a frequency level.
CMD_GET_FREQ_INFO: Get the current frequency.
CMD_SET_FREQ_INFO: Set the target frequency.
In future we will add automatic frequency scaling, which is similar to
Intel's HWP (HardWare P-State).

PCI devices and bridges DT nodes created during the PCI scan are created
with the interrupt-map property set to handle interrupts.
In order to set this interrupt-map property at a specific level, a
phandle to the parent interrupt controller is needed. On systems that
are not fully described by a device-tree, the parent interrupt
controller may be unavailable (i.e. not described by the device-tree).
As mentioned in the [1], avoiding the use of the interrupt-map property
and considering a PCI device as an interrupt controller itself avoid the
use of a parent interrupt phandle.
In that case, the PCI device itself as an interrupt controller is
responsible for routing the interrupts described in the device-tree
world (DT overlay) to the PCI interrupts.
Add the 'interrupt-controller' property in the PCI device DT node.

The str_array parameter has no reason to be an un-const array.
Indeed, elements of the 'str_array' array are not changed by the code.
Constify the 'str_array' array parameter.
With this const qualifier added, the following construction is allowed:
static const char * const tab_str[] = { "string1", "string2" };
of_changeset_add_prop_string_array(..., tab_str, ARRAY_SIZE(tab_str));

The HX83100A is a bit of an outlier in the Himax HX831xxx series of
touch controllers as it requires reading touch events through the AHB
interface of the MCU rather than providing a dedicated FIFO address like
the other chips do.
This patch implements the specific read function and introduces the
HX83100A chip with an appropriate i2c ID and DT compatible string.
The HX83100A doesn't have a straightforward way to do chip
identification, which is why it is not implemented in this patch.

Input core expects input handlers to be either filters, or regular
handlers, but not both. Additionally, for regular handlers it does
not make sense to define both single event method and batch method.
Refuse registering handler if it defines more than one method.

Imagis IST3038 is another variant of Imagis IST3038 IC, which has
a different register interface from IST3038C (possibly firmware defined).
Unlike IST3038C/IST3032C, IST3038 has different registers for commands,
which means IST3038 doesn't use protocol B.
Similar to IST3032C and maybe the other variants, IST3038 has touch keys
support, which provides KEY_APPSELECT and KEY_BACK.
Add support for IST3038 with touch keys.

xiic_start_xfer can fail for different reasons:
- EBUSY: bus is busy or i2c messages still in tx_msg or rx_msg
- ETIMEDOUT: timed-out trying to clear the RX fifo
- EINVAL: wrong clock settings
Both EINVAL and ETIMEDOUT will currently print a specific error
message followed by a generic one, for example:
Failed to clear rx fifo
Error xiic_start_xfer
however EBUSY will simply output the generic message:
Error xiic_start_xfer
which is not really helpful.
This commit adds a new error message when a busy condition is detected
and also removes the generic message since it does not provide any
relevant information to the user.

A device may need the controller up during suspend_noirq() or
resume_noirq().
But if the controller is autosuspended, there is no way to wakeup it during
suspend_noirq() or resume_noirq() because runtime pm is disabled at this
time.
The suspend() callback wakes up the controller, so it is available until
its suspend_noirq() callback (pm_runtime_force_suspend()).
During the resume, it's restored by resume_noirq() callback
(pm_runtime_force_resume()). Then resume() callback enables autosuspend.
So the controller is up during a little time slot in suspend and resume
sequences even if it's not used.
