Now, snd_soc_pcm_runtime supports multi cpu_dai/codec_dai.
It still has cpu_dai/codec_dai for single DAI,
and has cpu_dais/codec_dais for multi DAIs.
dais = [][][][][][][][][][][][][][][][][][]
^cpu_dais ^codec_dais
|--- num_cpus ---|--- num_codecs --|
/* for multi DAIs */
rtd->cpu_dais = &rtd->dais[0];
rtd->codec_dais = &rtd->dais[dai_link->num_cpus];
/* for single DAI */
rtd->cpu_dai = rtd->cpu_dais[0];
rtd->codec_dai = rtd->codec_dais[0];
But, these can be replaced by dais.
This patch adds asoc_rtd_to_cpu() / asoc_rtd_to_codec() macro for it.

Due to an issue with PCIe wrapper logic built for the DWC PCIe IP on
dra7xx, the driver needs to ensure that there are no pending MSI IRQ
vector set (i.e PCIE_MSI_INTR0_STATUS reads 0 at least once) before
exiting IRQ handler otherwise the dra7xx PCIe wrapper will not register
new MSI IRQs even though PCIE_MSI_INTR0_STATUS reports IRQs are pending.
Therefore it's no longer possible to use default IRQ handler provided by
DWC library.
Add an irqchip implementation inside pci-dra7xx.c and install new MSI
IRQ handler to handle the above errata.
This fixes a bug, where PCIe wifi cards with 4 DMA queues like Intel
8260 used to throw following error and stall during ping/iperf3 tests.
[ 97.776310] iwlwifi 0000:01:00.0: Queue 9 stuck for 2500 ms.

gcc 10 will default to -fno-common, which causes this error at link
time:
(.text+0x0): multiple definition of `yylloc'; dtc-lexer.lex.o (symbol from plugin):(.text+0x0): first defined here
This is because both dtc-lexer as well as dtc-parser define the same
global symbol yyloc. Before with -fcommon those were merged into one
defintion. The proper solution would be to to mark this as "extern",
however that leads to:
dtc-lexer.l:26:16: error: redundant redeclaration of 'yylloc' [-Werror=redundant-decls]
26 | extern YYLTYPE yylloc;

In file included from dtc-lexer.l:24:
dtc-parser.tab.h:127:16: note: previous declaration of 'yylloc' was here
127 | extern YYLTYPE yylloc;

cc1: all warnings being treated as errors
which means the declaration is completely redundant and can just be

The PERF_SAMPLE_CGROUP bit is to save (perf_event) cgroup information in
the sample. It will add a 64-bit id to identify current cgroup and it's
the file handle in the cgroup file system. Userspace should use this
information with PERF_RECORD_CGROUP event to match which cgroup it
belongs.
I put it before PERF_SAMPLE_AUX for simplicity since it just needs a
64-bit word. But if we want bigger samples, I can work on that
direction too.

To support cgroup tracking, add CGROUP event to save a link between
cgroup path and id number. This is needed since cgroups can go away
when userspace tries to read the cgroup info (from the id) later.
The attr.cgroup bit was also added to enable cgroup tracking from
userspace.
This event will be generated when a new cgroup becomes active.
Userspace might need to synthesize those events for existing cgroups.
Committer testing:
From the resulting kernel, using /sys/kernel/btf/vmlinux:
$ pahole perf_event_attr | grep -w cgroup -B5 -A1

SDIO irq is not triggered by low level, but by falling edge in our
previous IC. This mechanism only have one chance to catch the SDIO irq
if a SDIO irq comes within the multiple block transmission. This SDIO
irq may be easily lost, because falling edge appears only once within 2
clock after data transmission is completed.
SDIO irq recheck mechanism will make sure all irqs can be
