The EC of OneXPlayer devices used to only control the fan. This is no
longer the case, with the EC of OneXPlayer gaining additional
functionality (turbo button, turbo led, battery controls).
As it will be beneficial from a complexity perspective to retain this
driver as a single unit, move it out of hwmon, and into platform/x86.
Also, remove the hwmon documentation to prepare moving it to
Documentation/ABI/.
While at it, add myself to the maintainer's file.

Allow the special case of a redirect from a lower layer to a data layer
without having to turn on metacopy. This makes the feature work with
userxattr, which in turn allows data layers to be usable in user
namespaces.
Minimize the risk by only enabling redirect from a single lower layer to a
data layer iff a data layer is specified. The only way to access a data
layer is to enable this, so there's really no reason not to enable this.
This can be used safely if the lower layer is read-only and the
user.overlay.redirect xattr cannot be modified.

The generic FourCC format always prints the data using the big endian
order. It is generic because it allows to read the data using a custom
ordering.
The current code uses "n" for reading data in the reverse host ordering.
It makes the 4 variants [hnbl] consistent with the generic printing
of IPv4 addresses.
Unfortunately, it creates confusion on big endian systems. For example,
it shows the data &(u32)0x67503030 as
%p4cn 00Pg (0x30305067)
But people expect that the ordering stays the same. The network ordering
is a big-endian ordering.
The problem is that the semantic is not the same. The modifiers affect
the output ordering of IPv4 addresses while they affect the reading order
in case of FourCC code.
Avoid the confusion by replacing the "n" modifier with "hR", aka
reverse host ordering. It is inspired by the existing %p[mM]R printf
format.

The KVM PV ABI recently added a feature that allows the VM to discover
the set of physical CPU implementations, identified by a tuple of
{MIDR_EL1, REVIDR_EL1, AIDR_EL1}. Unlike other KVM PV features, the
expectation is that the VMM implements the hypercall instead of KVM as
it has the authoritative view of where the VM gets scheduled.
To do this the VMM needs to know the values of these registers on any
CPU in the system. While MIDR_EL1 and REVIDR_EL1 are already exposed,
AIDR_EL1 is not. Provide it in sysfs along with the other identification
registers.

Linux is intended to be compatible with userspace written to Arm's
AAPCS64 procedure call standard [1,2]. For the Scalable Matrix Extension
(SME), AAPCS64 was extended with a "ZA lazy saving scheme", where SME's
ZA tile is lazily callee-saved and caller-restored. In this scheme,
TPIDR2_EL0 indicates whether the ZA tile is live or has been saved by
pointing to a "TPIDR2 block" in memory, which has a "za_save_buffer"
pointer. This scheme has been implemented in GCC and LLVM, with
necessary runtime support implemented in glibc.
AAPCS64 does not specify how the ZA lazy saving scheme is expected to
interact with signal handling, and the behaviour that AAPCS64 currently
recommends for (sig)setjmp() and (sig)longjmp() does not always compose
safely with signal handling, as explained below.
When Linux delivers a signal, it creates signal frames which contain the
original values of PSTATE.ZA, the ZA tile, and TPIDR_EL2. Between saving
the original state and entering the signal handler, Linux clears
PSTATE.ZA, but leaves TPIDR2_EL0 unchanged. Consequently a signal
handler can be entered with PSTATE.ZA=0 (meaning accesses to ZA will
trap), while TPIDR_EL0 is non-null (which may indicate that ZA needs to
be lazily saved, depending on the contents of the TPIDR2 block). While
in this state, libc and/or compiler runtime code, such as longjmp(), may
attempt to save ZA. As PSTATE.ZA=0, these accesses will trap, causing
the kernel to inject a SIGILL. Note that by virtue of lazy saving
occurring in libc and/or C runtime code, this can be triggered by
application/library code which is unaware of SME.
To avoid the problem above, the kernel must ensure that signal handlers
are entered with PSTATE.ZA and TPIDR2_EL0 configured in a manner which
complies with the ZA lazy saving scheme. Practically speaking, the only
choice is to enter signal handlers with PSTATE.ZA=0 and TPIDR2_EL0=NULL.
This change should not impact SME code which does not follow the ZA lazy
saving scheme (and hence does not use TPIDR2_EL0).
An alternative approach that was considered is to have the signal
handler inherit the original values of both PSTATE.ZA and TPIDR2_EL0,
relying on lazy save/restore sequences being idempotent and capable of
racing safely. This is not safe as signal handlers must be assumed to
have a "private ZA" interface, and therefore cannot be entered with
PSTATE.ZA=1 and TPIDR2_EL0=NULL, but it is legitimate for signals to be
taken from this state.
With the kernel fixed to clear TPIDR2_EL0, there are a couple of
remaining issues (largely masked by the first issue) that must be fixed
in userspace:
(1) When a (sig)setjmp() + (sig)longjmp() pair cross a signal boundary,
ZA state may be discarded when it needs to be preserved.
Currently, the ZA lazy saving scheme recommends that setjmp() does
not save ZA, and recommends that longjmp() is responsible for saving
ZA. A call to longjmp() in a signal handler will not have visibility
of ZA state that existed prior to entry to the signal, and when a
longjmp() is used to bypass a usual signal return, unsaved ZA state
will be discarded erroneously.
To fix this, it is necessary for setjmp() to eagerly save ZA state,
and for longjmp() to configure PSTATE.ZA=0 and TPIDR2_EL0=NULL. This
works regardless of whether a signal boundary is crossed.
(2) When a C++ exception is thrown and crosses a signal boundary before
it is caught, ZA state may be discarded when it needs to be
preserved.
AAPCS64 requires that exception handlers are entered with
PSTATE.{SM,ZA}={0,0} and TPIDR2_EL0=NULL, with exception unwind code
expected to perform any necessary save of ZA state.
Where it is necessary to perform an exception unwind across an
exception boundary, the unwind code must recover any necessary ZA
state (along with TPIDR2) from signal frames.
Fix the kernel as described above, with setup_return() clearing
TPIDR2_EL0 when delivering a signal. Folk on CC are working on fixes for
the remaining userspace issues, including updates/fixes to the AAPCS64
specification and glibc.

The MHI registers are present in IPQ5332, IPQ6018, IPQ8074 and IPQ9574
SoCs. Hence, add the MHI registers to the binding to allow these registers
to be defined in devicetree.

Merge series from Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>:
Renesas MSIOF can work as both SPI and I2S.
Current Linux supports MSIOF-SPI. This patch-set adds new MSIOF-I2S.
Because it is using same HW-IP, we want to share same compatible for both
MSIOF-SPI/I2S case. MSIOF-I2S (Sound) will use Audio-Graph-Card/Card2 which
uses Of-Graph, but MSIOF-SPI is not use Of-Graph.
So, this patch-set assumes it was used as MSIOF-I2S if DT is using Of-Graph,
otherwise, it is MSIOF-SPI (This assumption will works if SPI *never*
use Of-Graph in the future).
One note so far is that it is using "spi@xxx" node name for both
MSIOF-SPI/I2S. DTC will automatically checks "spi@xxx" node as SPI device
which requests #address-cells/#size-cells. But is not needed for I2S.
So we will get warning about it on Sparrow Hawk which uses MSIOF-I2S.
We have no solution about it, so far.

Renesas MSIOF (Clock-Synchronized Serial Interface with FIFO) can work as
both SPI and I2S. MSIOF-I2S will use Audio Graph Card/Card2 driver which
uses Of-Graph in DT.
MSIOF-SPI/I2S are using same DT compatible properties.
MSIOF-I2S uses Of-Graph for Audio-Graph-Card/Card2,
MSIOF-SPI doesn't use Of-Graph.
Adds schema for MSIOF-I2S (= Sound).

These are already used in device trees, so describe them here. As the
driver only declares up through Tegra210, these must use a fallback
