A number of laptops have gone to market with old firmware versions that
export controls that have since been hidden, but we can't just install a
newer firmware because the firmware for each product is customized and
qualified by the OEM. The issue is that alsactl save and restore has no
idea what controls are good to persist which can lead to
misconfiguration.
There is no reason that the UCM or user should need to interact with any
of the ALSA controls for the firmware coefficients so they can be
removed entirely.

To enable the domain-idle-states to be used during s2idle on a PREEMPT_RT
based configuration, let's allow the re-assignment of the ->enter_s2idle()
callback to psci_enter_s2idle_domain_idle_state().
Similar to s2ram, let's leave the support for CPU hotplug outside
PREEMPT_RT, as it's depending on using runtime PM. For s2idle, this means
that an offline CPU's PM domain will remain powered-on. In practise this
may lead to that a shallower idle-state than necessary gets selected, which
shouldn't be an issue (besides wasting power).

The domain-idle-states are currently disabled on a PREEMPT_RT based

There is no need to hold the genpd-lock, while assigning the
dev->pm_domain. In fact, it becomes a problem on a PREEMPT_RT based
configuration as the genpd-lock may be a raw spinlock, while the lock
acquired through the call to dev_pm_domain_set() is a regular spinlock.
To fix the problem, let's simply move the calls to dev_pm_domain_set()
outside the genpd-lock.

To allow a genpd provider for a CPU PM domain to enter a domain-idle-state
during s2idle on a PREEMPT_RT based configuration, we can't use the regular
spinlock, as they are turned into sleepable locks on PREEMPT_RT.
To address this problem, let's convert into using the raw spinlock, but
only for genpd providers that have the GENPD_FLAG_CPU_DOMAIN bit set. In
this way, the lock can still be acquired/released in atomic context, which
is needed in the idle-path for PREEMPT_RT.
Do note that the genpd power-on/off notifiers may also be fired during
s2idle, but these are already prepared for PREEMPT_RT as they are based on
the raw notifiers. However, consumers of them may need to adopt accordingly
to work properly on PREEMPT_RT.

the vq coalescing parameters. This issue needs to be fixed.

In transmit path, it is likely that the iova is not aligned to PCIe TLP
max payload size, which is 128 for WCN7850. Normally in such cases hardware
is expected to split the packet into several parts in a manner such that
they, other than the first one, have aligned iova. However due to hardware
limitations, WCN7850 does not behave like that properly with some specific
unaligned iova in transmit path. This easily results in target hang in a
KPI transmit test: packet send/receive failure, WMI command send timeout
etc. Also fatal error seen in PCIe level:
...
Capabilities: ...
...
DevSta: ... FatalErr+ ...
...
...
Work around this by manually moving/reallocating payload buffer such that
we can map it to a 128 bytes aligned iova. The moving requires sufficient
head room or tail room in skb: for the former we can do ourselves a favor
by asking some extra bytes when registering with mac80211, while for the
latter we can do nothing.
Moving/reallocating buffer consumes additional CPU cycles, but the good news
is that an aligned iova increases PCIe efficiency. In my tests on some X86
platforms the KPI results are almost consistent.
Since this is seen only with WCN7850, add a new hardware parameter to
differentiate from others.

Linux kernel expects thermal zone node names to be maximum of 19
characters (see THERMAL_NAME_LENGTH, including terminating NUL byte) and
bindings/dtbs_check points that:
fsl-ls2088a-rdb.dtb: thermal-zones: 'core-cluster1-thermal', 'core-cluster2-thermal', 'core-cluster3-thermal', 'core-cluster4-thermal'
do not match any of the regexes: '^[a-zA-Z][a-zA-Z0-9\\-]{1,10}-thermal$', 'pinctrl-[0-9]+'
Name longer than 19 characters leads to driver probe errors when
registering such thermal zone.

The previous pinconf settings(made by the bootloader) need to be
overwritten when configuring the pinctrl of a driver during the boot
process.
Configuring the bias of a GPIO at runtime (e.g. pull-up) needs to
preserve the other settings unaltered.
This patch introduces changes to differentiate between the two cases.

Previously, it was possible to only configure the open-drain for a pin.
However, after a pin got configured with open-drain, there wasn't any
way to disable it. Add the push-pull configuration in order to reverse
the open-drain configuration.

The IBE (input buffer enable) should be enabled for a GPIO. Reading the
value will return the one from the input register, writing the value
will return the one from the output register.
This offers the flexibility to check if the value intended to be set
matches the actual physical one.

There is no need to describe the compatible string inside
a dtso file.
dt-schema produces super verbose warnings about that.
