Rename the PHY_C20_CUSTOM_SERDES / PHY_C20_CUSTOM_SERDES_MASK register
field names to PHY_C20_DP_RATE / PHY_C20_DP_RATE_MASK, and move the
definitions under the actual register containing the fields.

This assert can trigger here with non pin_map users that select
LATE_RESTORE, since the vmap is allowed to be NULL given that
save/restore can now use the blitter instead. The check here doesn't
seem to have much value anymore given that we no longer move pinned
memory, so any existing vmap is left well alone, and doesn't need to be
recreated upon restore, so just drop the assert here.

If the location madvise() is set to

Detect when PSE hardware is already configured (user byte == 42) and
skip hardware initialization to prevent power interruption to connected
devices during system reboots.
Previously, the driver would always reconfigure the PSE hardware on
probe, causing a port matrix reflash that resulted in temporary power
loss to all connected devices. This change maintains power continuity

While associating, firmware needs the peer's receive capability
to calculate its own VHT transmit MCS. Currently, the host
sends this information via mcs->rx_mcs_set field, but firmware
actually reads it from mcs->tx_mcs_set field. This mismatch is
incorrect.
This issue has not caused failures so far because most peers
advertise identical TX and RX capabilities. Fix this by
assigning the value to tx_mcs_set as expected.
Additionally, the rate control mask is intended to limit our
transmit MCS, so it should also apply to the peer's receive
capability. Update the logic accordingly.

Mac80211 schedules CSA finalize work twice during a channel switch: first
during the reserved switch phase and again during the finalize phase.
The beacon content is updated only during the second schedule, which occurs
after the reserved switch completes. However, the ath12k driver attempts to
bring up the VDEV during the channel switch callback
(ath12k_mac_update_vif_chan()), which leads to premature installation of
stale beacon templates before the updated content is available.
This premature VDEV bring-up causes outdated beacon information to be
broadcast, which can result in updated channel parameters during the
transition. In MBSSID scenarios, this behavior is particularly problematic
because the transmitting interface's beacon must be updated before
non-transmitting interfaces are brought up. Failing to do so can lead to
beacon mismatches across interfaces.
Introduce a is_csa_in_progress flag to defer VDEV_UP until CSA finalize is
complete. Set this flag during the channel switch callback when CSA is
active. In bss_info_changed(), check this flag and issue VDEV_UP only
after the beacon template has been updated.
Ensure that in MBSSID cases, the transmitting interface is brought up
first, followed by all non-transmitting interfaces. This ordering makes
sure correct beacon propagation and avoids stale beacon installation
during CSA transitions.
Additionally, move the call to ath12k_mac_update_peer_puncturing_width()
before VDEV bring-up during CSA handling. This ensures that the puncturing
bitmap and bandwidth settings are applied before the VDEV is brought up.

Currently, packets received on the REO exception ring from
unassociated peers are of MSDU buffer type, while the driver expects
link descriptor type packets. These packets are not parsed further due
to a return check on packet type in ath12k_hal_desc_reo_parse_err(),
but the associated skb is not freed. This may lead to kernel
crashes and buffer leaks.
Hence to fix, update the RX error handler to explicitly drop
MSDU buffer type packets received on the REO exception ring.
This prevents further processing of invalid packets and ensures
stability in the RX error handling path.

Hardware target implements an address space larger than that PCI BAR can
map. In order to be able to access the whole target address space, the BAR
space is split into 4 segments, of which the last 3, called windows, can
be dynamically mapped to the desired area. This is achieved by updating
window register with appropriate window value. Currently each time when
accessing a register that beyond ATH11K_PCI_WINDOW_START, host calculates
the window value and caches it after window update, this way next time
when accessing a register falling in the same window, host knows that the
window is already good hence no additional update needed.
However this mechanism breaks after global reset is triggered in
ath11k_pci_soc_global_reset(), because with global reset hardware resets
window register hence the window is not properly mapped any more. Current
host does nothing about this, as a result a subsequent register access may
not work as expected if it falls in a window same as before.
Although there is no obvious issue seen now, better to fix it to avoid
future problem. The fix is done by restoring the window register after
global reset.

Currently, ath10k has a recovery check logic. It will wait for the
last recovery to finish by wait_for_completion_timeout();
But in SDIO scenarios, the recovery function may be invoked from
interrupt context, where long blocking waits are undesirable and can
lead to system instability.
Additionally, Linux’s ordered workqueue processes one task at a time.
If a previous recovery is still queued or executing, new triggers are
ignored. This prevents accurate tracking of consecutive failures and
delays transition to the WEDGED state.
To address this, move the recovery check logic into a different
workqueue.

Currently, the BiosImage type in vbios code is implemented as a
type-wrapping enum with the sole purpose of implementing a type that is
common to all specific image types. To make this work, macros were used
to overcome limitations of using enums. Ugly match statements were also
required to route methods from the enum type to the specific image type.
Simplify the code by just creating the common BiosImage type in the
iterator, and then converting it to specific image type after. This
works well since all the methods common to different BiosImage are
called only during the iteration and not later. Should we need to call
these common methods later, we can use AsRef and traits, but for now not
doing so gives us a nice ~50 negative line delta versus the existing
code and is a lot simpler.
Also remove the now obsolete BiosImage enum type.

Because nova-core depends on CONFIG_64BIT and a raw DmaAddress is
always a u64, we can remove the now actually useless conversion.

In order to support correct initialization of the timer base in the HDMI
QP IP block, setup platform data to include the required reference clock
rate.
While at it, ensure plat_data is zero-initialized in
dw_hdmi_qp_rockchip_bind().

The error handling in dw_hdmi_qp_rockchip_bind() is quite inconsistent,
i.e. in some cases the error code is not included in the message, while
in some other cases there is no check for -EPROBE_DEFER.
Since this is part of the probe path, address the aforementioned issues
by switching to dev_err_probe(), which also reduces the code a bit.

Currently the TIMER_BASE_CONFIG0 register gets initialized to a fixed
value as initially found in vendor driver code supporting the RK3588
SoC. As a matter of fact the value matches the rate of the HDMI TX
reference clock, which is roughly 428.57 MHz.
However, on RK3576 SoC that rate is slightly lower, i.e. 396.00 MHz, and
the incorrect register configuration breaks CEC functionality.
Set the timer base according to the actual reference clock rate that
shall be provided by the platform driver. Otherwise fallback to the
vendor default.
While at it, also drop the unnecessary empty lines in
dw_hdmi_qp_init_hw().

Add support for the CEC interface of the Synopsys DesignWare HDMI QP TX
controller.
This is based on the downstream implementation, but rewritten on top of
the CEC helpers added recently to the DRM HDMI connector framework.
Also note struct dw_hdmi_qp_plat_data has been extended to include the
CEC IRQ number to be provided by the platform driver.

Add support for PMH0101/PMCX0102/PMH0110/PMH0104 PMIC voltage
regulators which are present on Glymur boards.
Introduce new LDOs & SMPSs under them (PMIC5 subtype 530 for
both).
For these new LDOs support a new optimum power mode(OPM). In
this mode LDO will automatically switch between high power mode
(HPM) and low power mode (LPM) based on the real-time LDO load
current. Its operation is analogous to SMPS AUTO mode.

Currently rpmh-regulator resource name inside CMD-DB follows this
format: `^(ldo|smp|bob|vs)[a-n][1-9][0-9]?$`
(eg - ldob11, smpa2, bobc1 etc)
Here `[a-n]` in the resource name signifies the `pmic-id`.
However, newer firmware follows a different format that also
includes the `bus_id` as well in the resource name.
New format:
`^(L|S|B)[1-9][0-9]?[A-N]_E[0-3]$`
(eg - L11B_E1, S2A_E0, B1C_E0 etc)
Here `_E[0-3]` at the end is the `bus_id`, and upper case `[A-N]`
is used to denote `pmic-id`, while the regulator `(ldo|smp|bob)`
is replaced with their initials in upper case `(L|S|B|VA)`.
To handle this properly, do the following:
- Remove the `resource_name` member from vreg init data
- Add `index` and `regulator_hw_type` new members, which will
contain the index number and the regulator hardware type
(SMPS/LDO/BOB/VS) which can be combined with the pmic-id read
from the devicetree to generate the resource_name.
- Choose new resource name format if `pmic-id` contains `_E`
in it, else fallback to old format.

Merge series from Haibo Chen <haibo.chen@nxp.com>:
PATCH 1: different operations maybe require different max frequency, so
add flexspi to handle such case, re-config the clock rate when
new coming operation require new clock frequency.
Patch 2: add workaround for erratum ERR050272. Since only add 4us dealy
in nxp_fspi_dll_calibration(), so do not distinguish different
platforms.
Patch 3: add max frequency limitation for different sample clock source
selection. Datasheet give max 66MHz for mode 0 and 166MHz for
mode 3. And IC suggest to add this limitation on all SoCs for
safety and stability.

The SCMI specification states that SENSOR_CONFIG_SET is used to
enable/disable the sensors. The sensors can be disabled by default,
which is the case at least on NXP i.MX95. Explicitly trigger the
SENSOR_CONFIG_SET to enable the sensors, otherwise sensor read may
fail and won't return valid data.
