iio: magnetometer: Add driver for Yamaha YAS530
This adds an IIO magnetometer driver for the Yamaha
YAS530 family of magnetometer/compass chips YAS530,
YAS532 and YAS533.
A quick survey of the source code released by different
vendors reveal that we have these variants in the family
with some deployments listed:
* YAS529 MS-3C (2005 Samsung Aries)
* YAS530 MS-3E (2011 Samsung Galaxy S Advance)
* YAS532 MS-3R (2011 Samsung Galaxy S4)
* YAS533 MS-3F (Vivo 1633, 1707, V3, Y21L)
* (YAS534 is a magnetic switch)
* YAS535 MS-6C
* YAS536 MS-3W
* YAS537 MS-3T (2015 Samsung Galaxy S6, Note 5)
* YAS539 MS-3S (2018 Samsung Galaxy A7 SM-A750FN)
The YAS529 is so significantly different from the
YAS53x variants that it will require its own driver.
The YAS537 and YAS539 have slightly different register
sets but have strong similarities so a common driver
patching this one will probably be reasonable.
The source code for Samsung Galaxy A7's YAS539 is not
that is significantly different from the YAS530 in the
Galaxy S Advance, so I believe we will only need this
one driver with quirks to handle all of them.
The YAS539 is actively announced on Yamaha's devices
site:
https://device.yamaha.com/en/lsi/products/e_compass/
This is a driver written from scratch using buffered
IIO and runtime PM handling regulators and reset.
Thanks to Andy Shevchenko for great help in finding all
the special kernel infrastructure functions and quirks
during review of this driver.

The iio-core extends the attr_group provided by the driver with its
own attributes. To be able to do this it:
1. Has its own (non const) io_dev_opaque.chan_attr_group attr_group struct
2. It allocates a new attrs array with room for both the drivers and its
own attributes
3. It copies over the driver provided attributes into the newly allocated
attrs array.
But the drivers attr_group may contain more then just the attrs array, it
may also contain an is_visible callback and at least the adi-axi-adc.c
is currently defining such a callback.
Change the attr_group copying code to also copy over the is_visible
callback, so that drivers can define one and have it workins as is
normal for attr_group-s all over the kernel.
Note that the is_visible callback takes an index into the array as
argument, so that indices of the driver's attributes must not change,
this is not a problem as the driver's own attributes are added first
to the newly allocated attrs array and the attributes handled by the
core are appended after the driver's attributes.

iio: xilinx-xadc: Add basic support for Ultrascale System Monitor
The xilinx-xadc IIO driver currently has support for the XADC in the Xilinx
7 series FPGAs. The system-monitor is the equivalent to the XADC in the
Xilinx UltraScale and UltraScale+ FPGAs.
The IP designers did a good job at maintaining backwards compatibility and
only minor changes are required to add basic support for the system-monitor
core.
The non backwards compatible changes are:
* Register map offset was moved from 0x200 to 0x400
* Only one ADC compared to two in the XADC
* 10 bit ADC instead of 12 bit ADC
* Two of the channels monitor different supplies
Add the necessary logic to accommodate these changes to support the
system-monitor in the XADC driver.
Note that this patch does not include support for some new features found
in the system-monitor like additional alarms, user supply monitoring and
secondary system-monitor access. This might be added at a later time.

This seems harmless, as the function should normally get inlined, with
the output directly written or not. In any case, the uninitialized data
is never used after get_user() fails.
As Dan mentions, it could still trigger an UBSAN runtime error, and it
is of course a bad idea to copy uninitialized variables, so just

PCI: tegra: Fix host link initialization
Commit
b9ac0f9dc8ea ("PCI: dwc: Move dw_pcie_setup_rc() to DWC common
code") broke enumeration of downstream devices on Tegra:
In non-working case (next-
20201211):
0001:00:00.0 PCI bridge: NVIDIA Corporation Device 1ad2 (rev a1)
0001:01:00.0 SATA controller: Marvell Technology Group Ltd. Device 9171 (rev 13)
0005:00:00.0 PCI bridge: NVIDIA Corporation Device 1ad0 (rev a1)
In working case (v5.10-rc7):
0001:00:00.0 PCI bridge: Molex Incorporated Device 1ad2 (rev a1)
0001:01:00.0 SATA controller: Marvell Technology Group Ltd. Device 9171 (rev 13)
0005:00:00.0 PCI bridge: Molex Incorporated Device 1ad0 (rev a1)
0005:01:00.0 PCI bridge: PLX Technology, Inc. Device 3380 (rev ab)

0005:03:00.0 USB controller: PLX Technology, Inc. Device 3380 (rev ab)
The problem seems to be dw_pcie_setup_rc() is now called twice before and
after the link up handling. The fix is to move Tegra's link up handling to
.start_link() function like other DWC drivers. Tegra is a bit more
complicated than others as it re-inits the whole DWC controller to retry
the link. With this, the initialization ordering is restored to match the
prior sequence.

drm/amd/display: avoid uninitialized variable warning
clang (quite rightly) complains fairly loudly about the newly added
mpc1_get_mpc_out_mux() function returning an uninitialized value if the
'opp_id' checks don't pass.
This may not happen in practice, but the code really shouldn't return
garbage if the sanity checks don't pass.
So just initialize 'val' to zero to avoid the issue.

genirq: Fix export of irq_to_desc() for powerpc KVM
Commit
64a1b95bb9fe ("genirq: Restrict export of irq_to_desc()") removed
the export of irq_to_desc() unless powerpc KVM is being built, because
there is still a use of irq_to_desc() in modular code there.
However it used:
#ifdef CONFIG_KVM_BOOK3S_64_HV
Which doesn't work when that symbol is =m, leading to a build failure:
ERROR: modpost: "irq_to_desc" [arch/powerpc/kvm/kvm-hv.ko] undefined!
Fix it by checking for the definedness of the correct symbol which is
CONFIG_KVM_BOOK3S_64_HV_MODULE.

device-dax: Fix range release
There are multiple locations that open-code the release of the last

dev_dax_trim_range() helper.

perf probe: Fix memory leak when synthesizing SDT probes
The argv_split() function must be paired with argv_free(), else we must
keep a reference to the argv array received or do the freeing ourselves,
in synthesize_sdt_probe_command() we were simply leaking that argv[]
array.

perf stat aggregation: Add separate thread member
A separate field isn't strictly required. The core field could be
re-used for thread IDs as a single field was used previously.
But separating them will avoid confusion and catch potential errors
where core IDs are read as thread IDs and vice versa.
Also remove the placeholder id field which is now no longer used.

perf stat aggregation: Add separate socket member
Add socket as a separate member so that it doesn't have to be packed

When the socket ID was larger than 8 bits the output appeared corrupted
or incomplete.
For example, here on ThunderX2 'perf stat' reports a socket of -1 and an
invalid die number:
./perf stat -a --per-die
The socket id number is too big.
Performance counter stats for 'system wide':
S-1-D255 128 687.99 msec cpu-clock # 57.240 CPUs utilized
...
S36-D0 128 842.34 msec cpu-clock # 70.081 CPUs utilized
...
And with --per-core there is an entry with an invalid core ID:
./perf stat record -a --per-core
The socket id number is too big.
Performance counter stats for 'system wide':
S-1-D255-C65535 128 671.04 msec cpu-clock # 54.112 CPUs utilized
...
S36-D0-C0 4 28.27 msec cpu-clock # 2.279 CPUs utilized

This fixes the "Session topology" self test on ThunderX2.
After this fix the output contains the correct socket and die IDs and no
longer prints a warning about the size of the socket ID:
./perf stat --per-die -a
