====================
net: dsa: vsc73xx: fix MDIO bus access and PHY opera
This series are extracted patches from net-next series [0].
The VSC73xx driver has issues with PHY configuration. This patch series
fixes most of them.
The first patch synchronizes the register configuration routine with the
datasheet recommendations.
Patches 2-3 restore proper communication on the MDIO bus. Currently,
the write value isn't sent to the MDIO register, and without a busy check,
communication with the PHY can be interrupted. This causes the PHY to
receive improper configuration and autonegotiation could fail.
The fourth patch removes the PHY reset blockade, as it is no longer
required.
After fixing the MDIO operations, autonegotiation became possible.
The last patch removes the blockade, which became unnecessary after
the MDIO operations fix.

Resetting the VSC73xx PHY was problematic because the MDIO bus, without
a busy check, read and wrote incorrect register values.
My investigation indicates that resetting the PHY only triggers changes
in configuration. However, improper register values written earlier
were only exposed after a soft reset.
The reset itself wasn't the issue; rather, the problem stemmed from
incorrect read and write operations.
A 'soft_reset' can now proceed normally. There are no reasons to keep
the VSC73xx from being reset.
This commit removes the reset blockade in the 'vsc73xx_phy_write'
function.

The VSC73xx has a busy flag used during MDIO operations. It is raised
when MDIO read/write operations are in progress. Without it, PHYs are
misconfigured and bus operations do not work as expected.

According to the datasheet description ("Port Mode Procedure" in 5.6.2),
the VSC73XX_MAC_CFG_WEXC_DIS bit is configured only for half duplex mode.
The WEXC_DIS bit is responsible for MAC behavior after an excessive
collision. Let's set it as described in the datasheet.

Some of these laptop models have quirk IDs that are identical but have
different amplifier parts fitted, this difference is described in the
ACPI information.
The solution introduced for this product family can derive the required
component binding information from ACPI instead of hardcoding it,
supports the new variants of the CS35L56 being used and has generalized
naming that makes it applicable to other ALC+amp combinations.

spi: Add empty versions of ACPI lookup functions
A patch from Richard Fitzgerald adding dummy versions of the ACPI lookup
functions for SPI:
Provide empty versions of acpi_spi_count_resources(),
acpi_spi_device_alloc() and acpi_spi_find_controller_by_adev()
if the real functions are not being built.
This commit fixes two problems with the original definitions:
1) There wasn't an empty version of these functions
2) The #if only depended on CONFIG_ACPI. But the functions are implemented
in the core spi.c so CONFIG_SPI_MASTER must also be enabled for the real
functions to exist.

Pull x86 fixes from Thomas Gleixner:
- Fix 32-bit PTI for real.
pti_clone_entry_text() is called twice, once before initcalls so that
initcalls can use the user-mode helper and then again after text is
set read only. Setting read only on 32-bit might break up the PMD
mapping, which makes the second invocation of pti_clone_entry_text()
find the mappings out of sync and failing.
Allow the second call to split the existing PMDs in the user mapping
and synchronize with the kernel mapping.
- Don't make acpi_mp_wake_mailbox read-only after init as the mail box
must be writable in the case that CPU hotplug operations happen after
boot. Otherwise the attempt to start a CPU crashes with a write to
read only memory.
- Add a missing sanity check in mtrr_save_state() to ensure that the
fixed MTRR MSRs are supported.
Otherwise mtrr_save_state() ends up in a #GP, which is fixed up, but
the WARN_ON() can bring systems down when panic on warn is set.

Pull time keeping fixes from Thomas Gleixner:
- Fix a couple of issues in the NTP code where user supplied values are
neither sanity checked nor clamped to the operating range. This
results in integer overflows and eventualy NTP getting out of sync.
According to the history the sanity checks had been removed in favor
of clamping the values, but the clamping never worked correctly under
all circumstances. The NTP people asked to not bring the sanity
checks back as it might break existing applications.
Make the clamping work correctly and add it where it's missing
- If adjtimex() sets the clock it has to trigger the hrtimer subsystem
so it can adjust and if the clock was set into the future expire
timers if needed. The caller should provide a bitmask to tell
hrtimers which clocks have been adjusted.
adjtimex() uses not the proper constant and uses CLOCK_REALTIME
instead, which is 0. So hrtimers adjusts only the clocks, but does
not check for expired timers, which might make them expire really
late. Use the proper bitmask constant instead.

During Linux graceful reboot, the GPIO interrupts are not disabled.
Since the drivers are not removed during graceful reboot,
the logic to call mlxbf3_gpio_irq_disable() is not triggered.
Interrupts that remain enabled can cause issues on subsequent boots.
For example, the mlxbf-gige driver contains PHY logic to bring up the link.
If the gpio-mlxbf3 driver loads first, the mlxbf-gige driver
will use a GPIO interrupt to bring up the link.
Otherwise, it will use polling.
The next time Linux boots and loads the drivers in this order, we encounter the issue:
- mlxbf-gige loads first and uses polling while the GPIO10
interrupt is still enabled from the previous boot. So if
the interrupt triggers, there is nothing to clear it.
- gpio-mlxbf3 loads.
- i2c-mlxbf loads. The interrupt doesn't trigger for I2C
because it is shared with the GPIO interrupt line which
was not cleared.
The solution is to add a shutdown function to the GPIO driver to clear and disable
all interrupts. Also clear the interrupt after disabling it in mlxbf3_gpio_irq_disable().

When a machine enters a sleep state while a trigger is associated to
an iio device that trigger is not resumed after exiting the sleep state:
provide iio device drivers a way to suspend and resume
the associated trigger to solve the aforementioned bug.
Each iio driver supporting external triggers is expected to call
iio_device_suspend_triggering before suspending,
and iio_device_resume_triggering upon resuming.

Add scaling support to STM32 DFSDM.
When used in an analog context, a DFSDM filter typically converts the data
from a sigma delta modulator. The IIO device associated to the DFSDM
filter provides these data as raw data.
The IIO device can provide scaling information (voltage and offset) to
allow conversion of raw data into physical values.
With the new binding based on IIO backend framework, the sigma delta
modulators are defined as backends providing scaling information.
The scaling is not supported with legacy binding.

The legacy sd modulator driver registers the sigma delta modulator as
an IIO channel provider. This implementation is not convenient when the
SD modulator has to be cascaded with another IIO device. The scaling
information is distributed across devices, which makes it difficult to
report consistent scaling data on IIO devices.
The solution is to expose these cascaded IIO devices as an aggregate
device, which report global scaling information.
Add IIO backend support to SD modulator to allow scaling information
management.

Move to generic channels binding to ease new backend framework adoption
and prepare the convergence with MDF IP support on STM32MP2 SoC family.
Legacy binding:
DFSDM is an IIO channel consumer.
SD modulator is an IIO channels provider.
The channel phandles are provided in DT through io-channels property
and channel indexes through st,adc-channels property.
New binding:
DFSDM is an IIO channel provider.
The channel indexes are given by reg property in channel child node.
This new binding is intended to be used with SD modulator IIO backends.
It does not support SD modulator legacy IIO devices.
The st,adc-channels property presence is used to discriminate
between legacy and backend bindings.
The support of the DFSDM legacy channels and SD modulator IIO devices
is kept for backward compatibility.

Allow to specify the reference voltage used by the SD modulator.
When the SD modulator is defined as an IIO backend, the reference
voltage can be used to evaluate scaling information of the IIO device.
The reference voltage is not used otherwise.

Change the DFSDM binding to use the new IIO backend framework,
along with the adoption of IIO generic channels.
This binding change allows to add scaling support to the DFSDM.
Keep the legacy binding as deprecated for backward compatibility.
The io-backends property is supported only in generic IIO channel
binding.
- Channel description with the generic binding (Audio and Analog):
Properties superseded by generic properties:
st,adc-channels: becomes "reg" property in channel node
st,adc-channel-names: becomes "label" property in channel node
Properties moved to channel child node:
st,adc-channel-types: becomes st,adc-channel-type
st,adc-channel-clk-src, st,adc-alt-channel
- Analog binding:
DFSDM filter channel is configured as an IIO backend consumer.
Add io-backends property in channel child nodes.
DFSDM is no more configured as a channel consumer from SD modulator.
Use of io-channels in DFSDM node is deprecated.
- Audio binding:
DFSDM audio DAI is configured as a channel consumer from DFSDM filter.
No change compare to legacy.
