Merge series from Francesco Dolcini <francesco@dolcini.it>:
This patch series adds DMIC and DRC support to the WM8904 driver, a new
of_ helper is added to simplify the driver code.
DRC functionality is added in the same patch series to provide the
necessary dynamic range control to make DMIC support useful.
The WM8904 supports digital microphones on two of its inputs:
IN1L/DMICDAT1 and IN1R/DMICDAT2. These two inputs can either be
connected to an ADC or to the DMIC system. There is an ADC for each
line, and only one DMIC block. This DMIC block is either connected to
DMICDAT1 or to DMICDAT2. One DMIC data line supports two digital
microphones via time multiplexing.
The pin's functionality is decided during hardware design (IN1L vs
DMICDAT1 and IN1R vs DMICDAT2). This is reflected in the Device Tree.
If one line is analog and one is DMIC, we need to be able to switch
between ADC and DMIC at runtime. The DMIC source is known from the
Device Tree. If both are DMIC inputs, we need to be able to switch the
DMIC source. There is no need to switch between ADC and DMIC at runtime.
Therefore, kcontrols are dynamically added by the driver depending on
its Device Tree configuration.
This is a heavy rework of a previous patch series provided by Alifer
Moraes and Pierluigi Passaro,
https://lore.kernel.org/lkml/20220307141041.27538-1-alifer.m@variscite.com.

The SD spec version 6.0 section 6.4.1.5 requires that Vdd must be
lowered to less than 0.5V for a minimum of 1 ms when powering off a
card. Increase wait to 15 ms so that voltage has time to drain down
to 0.5V and cards can power off correctly. Issues with voltage drain
time were only observed on Apollo Lake and Bay Trail host controllers
so this fix is limited to those devices.

Many spi-mem controller drivers have a very similar debug log at the
beginning of their ->exec_op() callback implementation. This debug log is
effectively useful, so let's create one that is complete and concise
enough, so developers no longer need to write their own. The verbosity
being high, VERBOSE_DEBUG will be required in this case.
Remove the debug log from individual drivers and propose a common one.

Currently the API emac_update_hardware_stats() reads different ICSSG
stats without any lock protection.
This API gets called by .ndo_get_stats64() which is only under RCU
protection and nothing else. Add lock to this API so that the reading of
statistics happens during lock.

*** DEADLOCK ***
This driver uses a global lock to protect the list of enumerated DMA
remapping units. It is necessary due to the driver's support for dynamic
addition and removal of remapping units at runtime.
Two distinct code paths require iteration over this remapping unit list:
- Device registration and probing: the driver iterates the list to
register each remapping unit with the upper layer IOMMU framework
and subsequently probe the devices managed by that unit.
- Global configuration: Upper layer components may also iterate the list
to apply configuration changes.
The lock acquisition order between these two code paths was reversed. This
caused lockdep warnings, indicating a risk of deadlock. Fix this warning
by releasing the global lock before invoking upper layer interfaces for
device registration.

Don't overwrite an IRTE that is posting IRQs to a vCPU with a posted MSI
entry if the host IRQ affinity happens to change. If/when the IRTE is
reverted back to "host mode", it will be reconfigured as a posted MSI or
remapped entry as appropriate.
Drop the "mode" field, which doesn't differentiate between posted MSIs and
posted vCPUs, in favor of a dedicated posted_vcpu flag. Note! The two
posted_{msi,vcpu} flags are intentionally not mutually exclusive; an IRTE
can transition between posted MSI and posted vCPU.

Add a helper to take care of reconfiguring an IRTE to deliver IRQs to the
host, i.e. not to a vCPU, and use the helper when an IRTE's vCPU affinity
is nullified, i.e. when KVM puts an IRTE back into "host" mode. Because
posted MSIs use an ephemeral IRTE, using modify_irte() puts the IRTE into
full remapped mode, i.e. unintentionally disables posted MSIs on the IRQ.

The global dma_dev trick was mostly because the old domain_alloc op
provided no context, so no way to know which IOMMU was to own the
pagetable, or if a suitable one even existed at all. In the new
multi-instance world with domain_alloc_paging this is no longer a
concern - now we know that the given device must be associated with a
valid IOMMU instance which provided the op to call in the first place,
and therefore that instance can and should be the pagetable owner. To
avoid worrying about the lifetime and stability of the rk_domain->iommus
list, and keep the lookups simple and efficient, we'll still stash a
dma_dev pointer, but now it's accurately per-domain.

Currently Rockchip calls iommu_device_register() before it's finished
setting up the hardware and driver state, and as such it now gets
unhappy in various ways when registration starts working the way it was
always intended to, and probing client devices straight away. Reorder
the operations to ensure that what we're registering is a prepared and
functional IOMMU instance.

Now that DT-based probing is finally happening in the right order again,
it reveals an issue in Rockchip's of_xlate, which can now be called
during registration, but is using the global dma_dev which is only
assigned later. However, this makes little sense when we're already
looking up the correct IOMMU device, who should logically be the owner
of the devm allocation anyway.

The ravb_ptp_extts() function checks the flags coming from the
PTP_EXTTS_REQUEST ioctl, to ensure that future flags are not accepted on
accident.
This was updated to 'honor' the PTP_STRICT_FLAGS in commit 6138e687c7b6
("ptp: Introduce strict checking of external time stamp options.").
However, the driver does not *actually* validate the flags.
I originally fixed this driver to reject future flags in commit
592025a03b34 ("renesas: reject unsupported external timestamp flags"). It
is still unclear whether this hardware timestamps the rising, falling, or
both edges of the input signal.
Accepting requests with PTP_STRICT_FLAGS is a bug, as this could lead to
users mistakenly assuming a request with PTP_RISING_EDGE actually
timestamps the rising edge only.
Reject requests with PTP_STRICT_FLAGS (and hence all PTP_EXTTS_REQUEST2
requests) until someone with access to the datasheet or hardware knowledge
can confirm the timestamping behavior and update this driver.

The igb_ptp_feature_enable_82580 function correctly checks that unknown
flags are not passed to the function. However, it does not actually check
PTP_RISING_EDGE or PTP_FALLING_EDGE when configuring the external timestamp
function.
The data sheet for the 82580 product says:
Upon a change in the input level of one of the SDP pins that was
configured to detect Time stamp events using the TSSDP register, a time
stamp of the system time is captured into one of the two auxiliary time
stamp registers (AUXSTMPL/H0 or AUXSTMPL/H1).
For example to define timestamping of events in the AUXSTMPL0 and
AUXSTMPH0 registers, Software should:
1. Set the TSSDP.AUX0_SDP_SEL field to select the SDP pin that detects
the level change and set the TSSDP.AUX0_TS_SDP_EN bit to 1.
2. Set the TSAUXC.EN_TS0 bit to 1 to enable timestamping
The same paragraph is in the i350 and i354 data sheets.
The wording implies that the time stamps are captured at any level change.
There does not appear to be any way to only timestamp one edge of the
signal.
Reject requests which do not set both PTP_RISING_EDGE and PTP_FALLING_EDGE
when operating under PTP_STRICT_FLAGS mode via PTP_EXTTS_REQUEST2.

phy_loopback() leaves it to the PHY driver to select the speed of the
loopback mode. Thus, the speed of the loopback mode depends on the PHY
driver in use.
Add support for speed selection to phy_loopback() to enable loopback
with defined speeds. Ensure that link up is signaled if speed changes
as speed is not allowed to change during link up. Link down and up is
necessary for a new speed.

PHY drivers support loopback mode, but it is not possible to select the
