Dell headset mode platform with ALC236.
It doesn't recording after system resume from S3.
S3 mode was deep. s2idle was not has this issue.
S3 deep will cut of codec power. So, the register will back to default
after resume back.
This patch will solve this issue.

When enabling or disabling the vcpu dispatch statistics, we do a lot of
work including allocating/deallocating memory across all possible cpus
for the DTL buffer. In order to guard against hogging the cpu for too
long, track the time we're taking and yield the processor if necessary.

For Shared Processor LPARs, the POWER Hypervisor maintains a
relatively static mapping of the LPAR processors (vcpus) to physical
processor chips (representing the "home" node) and tries to always
dispatch vcpus on their associated physical processor chip. However,
under certain scenarios, vcpus may be dispatched on a different
processor chip (away from its home node). The actual physical
processor number on which a certain vcpu is dispatched is available to
the guest in the 'processor_id' field of each DTL entry.
The guest can discover the home node of each vcpu through the
H_HOME_NODE_ASSOCIATIVITY(flags=1) hcall. The guest can also discover
the associativity of physical processors, as represented in the DTL
entry, through the H_HOME_NODE_ASSOCIATIVITY(flags=2) hcall.
These can then be compared to determine if the vcpu was dispatched on
its home node or not. If the vcpu was not dispatched on the home node,
it is possible to determine if the vcpu was dispatched in a different
chip, socket or drawer.
Introduce a procfs file /proc/powerpc/vcpudispatch_stats that can be
used to obtain these statistics. Writing '1' to this file enables
collecting the statistics, while writing '0' disables the statistics.
The statistics themselves are available by reading the procfs file. By
default, the DTLB log for each vcpu is processed 50 times a second so
as not to miss any entries. This processing frequency can be changed
through /proc/powerpc/vcpudispatch_stats_freq.

Since we would be introducing a new user of the DTL buffer in a
subsequent patch, we need a way to gatekeep use of the DTL buffer.
The current debugfs interface for DTL allows registering and opening
cpu-specific DTL buffers. Cpu specific files are exposed under
debugfs 'powerpc/dtl/' node, and changing 'dtl_event_mask' in the same
directory enables controlling the event mask used when registering DTL
buffer for a particular cpu.
Subsequently, we will be introducing a user of the DTL buffers that
registers access to the DTL buffers across all cpus with the same event
mask. To ensure these two users do not step on each other, we introduce
a rwlock to gatekeep DTL buffer access. This fits the requirement of the
current debugfs interface wanting to allow multiple independent
cpu-specific users (read lock), and the subsequent user wanting
exclusive access (write lock).

When CONFIG_VIRT_CPU_ACCOUNTING_NATIVE is enabled, we always initialize
DTL enable mask to DTL_LOG_PREEMPT (0x2). There are no other places
where the mask is changed. As such, when reading the DTL log buffer
through debugfs, there is no need to save and restore the previous mask
value.
We don't need to save and restore the earlier mask value if
CONFIG_VIRT_CPU_ACCOUNTING_NATIVE is not enabled. So, remove the field
from the structure as well.

When using the legacy clock framework, clock pointers are no longer

Notify drm core before sending pending events during crtc disable.
This fixes the first event after disable having an old stale timestamp
by having drm_crtc_vblank_off update the timestamp to now.
This was seen while debugging weston log message:
Warning: computed repaint delay is insane: -8212 msec
This occurred due to:
1. driver starts up
2. fbcon comes along and restores fbdev, enabling vblank
3. vblank_disable_fn fires via timer disabling vblank, keeping vblank
seq number and time set at current value
(some time later)
4. weston starts and does a modeset
5. atomic commit disables crtc while it does the modeset
6. ipu_crtc_atomic_disable sends vblank with old seq number and time

We make the invalid assumption in arm_smmu_detach_dev() that the ATC is
clear after calling pci_disable_ats(). For one thing, only enabling the
PCIe ATS capability constitutes an implicit invalidation event, so the
comment was wrong. More importantly, the ATS capability isn't necessarily
disabled by pci_disable_ats() in a PF, if the associated VFs have ATS
enabled. Explicitly invalidate all ATC entries in arm_smmu_detach_dev().
The endpoint cannot form new ATC entries because STE.EATS is clear.

Enable compile-testing of the stp-xway GPIO driver now that it does not
depend on any architecture specific includes anymore.

Use the xway_stp_{r,w}32 helpers in xway_stp_w32_mask instead of relying
on ltq_{r,w}32 from the architecture specific <lantiq_soc.h>.
This will allow the driver to be compile-tested on all architectures
that support MMIO.

Three module clock error handling improvements:
- use devm_clk_get() so the clock instance can be freed if
devm_gpiochip_add_data() fails later on
- switch to clk_prepare_enable() so the driver is ready whenever the
lantiq target switches to the common clock framework
- disable the clock again (using clk_disable_unprepare()) if
devm_gpiochip_add_data()
All of these are virtually no-ops with the current lantiq target.
However, these will be relevant if we switch to the common clock
framework.

Return early if devm_gpiochip_add_data() returns an error instead of
having two consecutive "if (!ret) ..." statements.
Also make xway_stp_hw_init() return void because it unconditionally
returns 0. While here also update the kerneldoc comment for
xway_stp_hw_init().
These changes makes the error handling within the driver consistent.
No functional changes intended.
