To be more resilient to codec-detection failures when the hardware
powers on slowly, add retry mechanism to the device verification check.
Similar pattern is found throughout a number of Realtek codecs. Our
tests show that 60ms delay is sufficient to address readiness issues on
rt5640 chip.

When widebus was enabled for DisplayPort in commit c7c4122026
("drm/msm/dp: enable widebus on all relevant chipsets") it was clarified
that it is only supported on DPU 5.0.0 onwards which includes SC7180 on
DPU revision 6.2. However, this patch missed that the description
structure for SC7180 is also reused for SDM845 (because of identical
io_start address) which is only DPU 4.0.0, leading to a wrongly enbled
widebus feature and corruption on that platform.
Create a separate msm_dp_desc_sdm845 structure for this SoC compatible,
with the wide_bus_supported flag turned off.

Qcom lpass is using component->id to keep DAI ID (A).
(S) static int lpass_platform_pcmops_open(
sruct snd_soc_component *component,
struct snd_pcm_substream *substream)
{ ^^^^^^^^^(B0)
...
(B1) struct snd_soc_pcm_runtime *soc_runtime = snd_soc_substream_to_rtd(substream);
(B2) struct snd_soc_dai *cpu_dai = snd_soc_rtd_to_cpu(soc_runtime, 0);
...
(B3) unsigned int dai_id = cpu_dai->driver->id;
(A) component->id = dai_id;
...
}
This driver can get dai_id from substream (B0 - B3).
In this driver, below functions get dai_id from component->id (A).
(X) lpass_platform_pcmops_suspend()
(Y) lpass_platform_pcmops_resume()
(Z) lpass_platform_copy()
Here, (Z) can get it from substream (B0 - B3), don't need to use
component->id (A). On suspend/resume (X)(Y), dai_id can only be obtained
from component->id (A), because there is no substream (B0) in function
parameter.
But, component->id (A) itself should not be used for such purpose.
It is intilialized at snd_soc_component_initialize(), and parsed its ID
(= component->id) from device name (a).
int snd_soc_component_initialize(...)
{
...
if (!component->name) {
(a) component->name = fmt_single_name(dev, &component->id);
... ^^^^^^^^^^^^^
}
...
}
Unfortunately, current code is broken to start with.
There are many regmaps that the driver cares about, however its only
managing one (either dp or i2s) in component suspend/resume path.
I2S regmap is mandatory however other regmaps are setup based on flags
like "hdmi_port_enable" and "codec_dma_enable".
Correct thing for suspend/resume path to handle is by checking these
flags, instead of using component->id.

Sound machine drivers for Qualcomm SoCs can be reused across multiple
SoCs. But user space ALSA UCM files depend on the card driver name which
should be set per board/SoC.
Allow such customization by using driver match data as sound card driver
name. The QRB4210 RB2 gets its name set to "sm4250" as requested by
Srinivas Kandagatla, and since no (known) UCM has been written yet this
should not break anything.

Pull x86 fixes from Thomas Gleixner:
"A small set of x86 fixes:
- Cure IO bitmap inconsistencies
A failed fork cleans up all resources of the newly created thread
via exit_thread(). exit_thread() invokes io_bitmap_exit() which
does the IO bitmap cleanups, which unfortunately assume that the
cleanup is related to the current task, which is obviously bogus.
Make it work correctly
- A lockdep fix in the resctrl code removed the clearing of the
command buffer in two places, which keeps stale error messages
around. Bring them back.
- Remove unused trace events"

For the RAPL package energy status counter, Intel and AMD share the same
perf_subsys and perf_name, but with different MSR addresses.
Both rapl_counter_arch_infos[0] and rapl_counter_arch_infos[1] are
introduced to describe this counter for different Vendors.
As a result, the perf counter is probed twice, and causes a failure in
in get_rapl_counters() because expected_read_size and actual_read_size
don't match.
Fix the problem by skipping the already probed counter.
Note, this is not a perfect fix. For example, if different
vendors/platforms use the same MSR value for different purpose, the code
can be fooled when it probes a rapl_counter_arch_infos[] entry that does
not belong to the running Vendor/Platform.
In a long run, better to put rapl_counter_arch_infos[] into the
platform_features so that this becomes Vendor/Platform specific.

platform_features->rapl_msrs describes the RAPL MSRs supported. While
RAPL Perf counters can be exposed from different kernel backend drivers,
e.g. RAPL MSR I/F driver, or RAPL TPMI I/F driver.
Thus, turbostat should first blindly probe all the available RAPL Perf
counters, and falls back to the RAPL MSR counters if they are listed in
platform_features->rapl_msrs.
With this, platforms that don't have RAPL MSRs can clear the
platform_features->rapl_msrs bits and use RAPL Perf counters only.
