Antoine Tenart dd0da407bb arm64: dts: marvell: armada-cp110: describe more PPv2 interrupts
This patch describes 3 additional interrupts per PPv2 port. Those
interrupts will be used later in future versions of the Marvell PPv2
driver, and now the device tree description matches the hardware
capabilities.

Antoine Tenart eeee84f7a6 arm64: dts: marvell: armada-cp110: change the PPv2 IRQ names
This patch changes the PPv2 IRQ names in the CP110 device tree to match
a corresponding change in the Marvell PPv2 driver. The reason this was
updated is the IRQ where names after Tx/Rx interrupts, but this is not
true and can be configured. A following patch will add more of them and
the names wouldn't make sense.

DSI controllers are also the hosts of their dsi bus and therefore contain

Jun Yao 8eb7e28d4c arm64/mm: move runtime pgds to rodata
Now that deliberate writes to swapper_pg_dir are made via the fixmap, we
can defend against errant writes by moving it into the rodata section.
Since tramp_pg_dir and reserved_ttbr0 must be at a fixed offset from
swapper_pg_dir, and are not modified at runtime, these are also moved
into the rodata section. Likewise, idmap_pg_dir is not modified at
runtime, and is moved into rodata.

Jun Yao 2330b7ca78 arm64/mm: use fixmap to modify swapper_pg_dir
Once swapper_pg_dir is in the rodata section, it will not be possible to
modify it directly, but we will need to modify it in some cases.

To enable this, we can use the fixmap when deliberately modifying
swapper_pg_dir. As the pgd is only transiently mapped, this provides
some resilience against illicit modification of the pgd, e.g. for
Kernel Space Mirror Attack (KSMA).

Jun Yao 2b5548b681 arm64/mm: Separate boot-time page tables from swapper_pg_dir
Since the address of swapper_pg_dir is fixed for a given kernel image,
it is an attractive target for manipulation via an arbitrary write. To
mitigate this we'd like to make it read-only by moving it into the
rodata section.

We require that swapper_pg_dir is at a fixed offset from tramp_pg_dir
and reserved_ttbr0, so these will also need to move into rodata.
However, swapper_pg_dir is allocated along with some transient page
tables used for boot which we do not want to move into rodata.

As a step towards this, this patch separates the boot-time page tables
into a new init_pg_dir, and reduces swapper_pg_dir to the single page it
needs to be. This allows us to retain the relationship between
swapper_pg_dir, tramp_pg_dir, and swapper_pg_dir, while cleanly
separating these from the boot-time page tables.

The init_pg_dir holds all of the pgd/pud/pmd/pte levels needed during
boot, and all of these levels will be freed when we switch to the
swapper_pg_dir, which is initialized by the existing code in
paging_init(). Since we start off on the init_pg_dir, we no longer need
to allocate a transient page table in paging_init() in order to ensure
that swapper_pg_dir isn't live while we initialize it.

There should be no functional change as a result of this patch.

In subsequent patches we'll use a transient pgd during the primary cpu's
boot process. To make this work while allowing secondary cpus to use the
swapper_pg_dir, we need to pass the relevant TTBR1 pgd as a parameter

This patch updates __enable__mmu() to take this as a parameter, updating
callsites to pass swapper_pg_dir for now.

Robin Murphy 7adb562c3e arm64/dma-mapping: Mildly optimise non-coherent IOMMU ops
Whilst the symmetry of deferring to the existing sync callback in
__iommu_map_page() is nice, taking a round-trip through
iommu_iova_to_phys() is a pretty heavyweight way to get an address we
can trivially compute from the page we already have. Tweaking it to just
perform the cache maintenance directly when appropriate doesn't really
make the code any more complicated, and the runtime efficiency gain can
only be a benefit.

Furthermore, the sync operations themselves know they can only be

Yoshihiro Shimoda 737e05bf03 arm64: dts: renesas: revise properties for R-Car Gen3 SoCs' usb 2.0
R-Car Gen3 SoCs need to enable/deassert clocks/resets of both usb 2.0
host (included phy) and peripheral. Otherwise, other side device
cannot work correctly. So, this patch revises properties of clocks
and resets. After that, each device driver can enable/deassert
clocks/resets by its self.

Notes:
 - To work the renesas_usbhs driver correctly when host side drivers
   are disabled and the renesas_usbhs driver doesn't have multiple
   clock management, this patch doesn't change the order of the clocks
   property in each hsusb node.
 - This patch doesn't have any side-effects even if the renesas_usbhs
   driver doesn't have reset_control and multiple clock management.

Steve Capper 031e6e6b4e arm64: hugetlb: Avoid unnecessary clearing in huge_ptep_set_access_flags
For contiguous hugetlb, huge_ptep_set_access_flags performs a
get_clear_flush (which then flushes the TLBs) even when no change of ptes
is necessary.

Unfortunately, this behaviour can lead to back-to-back page faults being
generated when running with multiple threads that access the same
contiguous huge page.

Thread 1                     |  Thread 2
-----------------------------+------------------------------
hugetlb_fault                |
huge_ptep_set_access_flags   |
  -> invalidate pte range    | hugetlb_fault
continue processing          | wait for hugetlb_fault_mutex
release mutex and return     | huge_ptep_set_access_flags
                             |   -> invalidate pte range
hugetlb_fault
...

This patch changes huge_ptep_set_access_flags s.t. we first read the
contiguous range of ptes (whilst preserving dirty information); the pte
range is only then invalidated where necessary and this prevents further
spurious page faults.

In the contiguous bit hugetlb break-before-make code we assume that all
hugetlb pages are young.

In fact, remove_migration_pte is able to place an old hugetlb pte so
this assumption is not valid.

This patch fixes the contiguous hugetlb scanning code to preserve young
ptes.

Since the same family members of Rock960 boards (Rock960 and Ficus)
share the same configuration, split out the common nodes into a common

Ficus boards are then placed in corresponding board DTS file.

Below are some of the key differences between both Rock960 and Ficus
boards:

1. Different host enable GPIO for USB
2. Different power and reset GPIO for PCI-E
3. No Ethernet port on Rock960

Only the properties which differ between both boards are placed in the
board specific dts and the reset of the nodes are placed in common dtsi

Vicente Bergas 88a20edf76 arm64: dts: rockchip: Fix microSD in rk3399 sapphire board
The microSD card slot in the Sapphire board is not working because of
several issues:
 1.- The vmmc power supply is missing in the DTS. It is capable of 3.0V
 and has a GPIO-based enable control.
 2.- The vqmmc power supply can provide up to 3.3V, but it is capped in
 the DTS to just 3.0V because of the vmmc capability. This results in a
 conflict from the mmc driver requesting an unsupportable voltage range
 from 3.3V to 3.0V (min > max) as reported in dmesg. So, extend the
 range up to 3.3V. The hw should be able to stand this 0.3V tolerance.
 See mmc_regulator_set_vqmmc in drivers/mmc/core/core.c.
 3.- The card detect signal is non-working. There is a known conflict
 with jtag, but the workaround in drivers/soc/rockchip/grf.c does not
 work. Adding the broken-cd attribute to the DTS fixes the issue.

include/linux/mmzone.h describes ARCH_HAS_HOLES_MEMORYMODEL as
relevant when parts the memmap have been free()d. This would
happen on systems where memory is smaller than a sparsemem-section,
and the extra struct pages are expensive. pfn_valid() on these
systems returns true for the whole sparsemem-section, so an extra
memmap_valid_within() check is needed.

On arm64 we have nomap memory, so always provide pfn_valid() to test
for nomap pages. This means ARCH_HAS_HOLES_MEMORYMODEL's extra checks
are already rolled up into pfn_valid().

Remove it.

Armv8.4-A extension enables MRS instruction encodings inside ESR_ELx.ISS
during exception class ESR_ELx_EC_SYS64 (0x18). This encoding can be used
to emulate MRS instructions which can avoid fetch/decode from user space
thus improving performance. This adds a new sys64_hook structure element

Anshuman Khandual 520ad98871 arm64/cpufeatures: Factorize emulate_mrs()
MRS emulation gets triggered with exception class (0x00 or 0x18) eventually
calling the function emulate_mrs() which fetches the user space instruction
and analyses it's encodings (OP0, OP1, OP2, CRN, CRM, RT). The kernel tries
to emulate the given instruction looking into the encoding details. Going
forward these encodings can also be parsed from ESR_ELx.ISS fields without
requiring to fetch/decode faulting userspace instruction which can improve
performance. This factorizes emulate_mrs() function in a way that it can be
called directly with MRS encodings (OP0, OP1, OP2, CRN, CRM) for any given
target register which can then be used directly from 0x18 exception class.

Ard Biesheuvel 2e5d2f33d1 crypto: arm64/aes-blk - improve XTS mask handling
The Crypto Extension instantiation of the aes-modes.S collection of
skciphers uses only 15 NEON registers for the round key array, whereas
the pure NEON flavor uses 16 NEON registers for the AES S-box.

This means we have a spare register available that we can use to hold
the XTS mask vector, removing the need to reload it at every iteration
of the inner loop.

Since the pure NEON version does not permit this optimization, tweak
the macros so we can factor out this functionality. Also, replace the
literal load with a short sequence to compose the mask vector.

On Cortex-A53, this results in a ~4% speedup.

Ard Biesheuvel dd597fb33f crypto: arm64/aes-blk - add support for CTS-CBC mode
Currently, we rely on the generic CTS chaining mode wrapper to
instantiate the cts(cbc(aes)) skcipher. Due to the high performance
of the ARMv8 Crypto Extensions AES instructions (~1 cycles per byte),
any overhead in the chaining mode layers is amplified, and so it pays
off considerably to fold the CTS handling into the SIMD routines.

On Cortex-A53, this results in a ~50% speedup for smaller input sizes.

The reasoning of commit f10dc56c64 ("crypto: arm64 - revert NEON yield
for fast AEAD implementations") applies equally to skciphers: the walk
API already guarantees that the input size of each call into the NEON
code is bounded to the size of a page, and so there is no need for an
additional TIF_NEED_RESCHED flag check inside the inner loop. So revert
the skcipher changes to aes-modes.S (but retain the mac ones)

This partially reverts commit 0c8f838a52.

Add initial devicetree support for Hisilicon Hi3670 SoC which
is similar to Hi3660 SoC with NPU support.

This SoC has Octal core BigLittle CPUs in two clusters(4 * A53 & 4 * A73).

Only UART6 has been added for console support which is
pre configured by the bootloader. A fixed clock is sourcing
the UART6 which will get replaced by the clock driver when available.

Viresh Kumar b27dedf551 arm64: dts: hisilicon: Add missing clocks property for CPUs
The clocks property should either be present for all the CPUs of a
cluster or none. If these are present only for a subset of CPUs of a
cluster then things will start falling apart as soon as the CPUs are
brought online in a different order. For example, this will happen
because the operating system looks for such properties in the CPU node
it is trying to bring up, so that it can register a cooling device.

the 4GB address space of the SoC (cbass_main) in addition to the
register space. The size of the address space above the 4GB SoC address
space is 4GB. These address ranges will be used by CPU/DMA to access
the PCIe address space. In order to represent the address space above
the 4GB SoC address space and to represent the size of this address
space as 4GB, change address-cells and size-cells of interconnect to 2.

Since OSPI has similar need in MCU Domain Memory Map, change

For the guest we encode CNP bit while building vttbr, so we don't need
to bother with that in a world switch.

Vladimir Murzin 5ffdfaedfa arm64: mm: Support Common Not Private translations
Common Not Private (CNP) is a feature of ARMv8.2 extension which
allows translation table entries to be shared between different PEs in
the same inner shareable domain, so the hardware can use this fact to
optimise the caching of such entries in the TLB.

CNP occupies one bit in TTBRx_ELy and VTTBR_EL2, which advertises to
the hardware that the translation table entries pointed to by this
TTBR are the same as every PE in the same inner shareable domain for
which the equivalent TTBR also has CNP bit set. In case CNP bit is set
but TTBR does not point at the same translation table entries for a
given ASID and VMID, then the system is mis-configured, so the results
of translations are UNPREDICTABLE.

For kernel we postpone setting CNP till all cpus are up and rely on
cpufeature framework to 1) patch the code which is sensitive to CNP
and 2) update TTBR1_EL1 with CNP bit set. TTBR1_EL1 can be
reprogrammed as result of hibernation or cpuidle (via __enable_mmu).
For these two cases we restore CnP bit via __cpu_suspend_exit().

There are a few cases we need to care of changes in TTBR0_EL1:
  - a switch to idmap
  - software emulated PAN

we rule out latter via Kconfig options and for the former we make
sure that CNP is set for non-zero ASIDs only.

Suzuki K Poulose 74e248286e arm64: sysreg: Clean up instructions for modifying PSTATE fields
Instructions for modifying the PSTATE fields which were not supported
in the older toolchains (e.g, PAN, UAO) are generated using macros.
We have so far used the normal sys_reg() helper for defining the PSTATE
fields. While this works fine, it is really difficult to correlate the
code with the Arm ARM definition.

As per Arm ARM, the PSTATE fields are defined only using Op1, Op2 fields,
with fixed values for Op0, CRn. Also the CRm field has been reserved
for the Immediate value for the instruction. So using the sys_reg()
looks quite confusing.

This patch cleans up the instruction helpers by bringing them
in line with the Arm ARM definitions to make it easier to correlate
code with the document. No functional changes.

that this will leave us with one "host" and one "peripheral" port.

In order for host mode this to work, we assume that the bootloader
left things configured enough for us.  Apparently the magic for that
is is to do these writes on pmi8998:

  are very similar, this is probably the right call since boards
  could make changes to the way these regulators are hooked up and
  trying to find a way to avoid duplication will result in some
  confusing node overrides.
- Regulators that are hooked up to supply pins on the SoC are given
  an alias matching the name of that pin (pin name comes from the
  Qualcomm SoC "device specification" doc).
- Other regulator labels are based on the schematic.  If there is
  more than one logical name on the schematic for the same rail the
  secondary names are also listed and should be referred to as
  appropriate.
- Regulators all default to HPM mode w/ no ability to switch modes.
  Future patches can switch things to LPM and possibly add
  dynamic load switching if we have determined there's a benefit.
  This should only be done for rails where we'll actually be able
  to take advantage of the lower power modes so we don't need to
  churn with lots of patches adding regulator_set_load() calls
  to drivers.

NOTE: This patch is loosely based on one originally shared to me by
David Collins.

Will Deacon ace8cb7545 arm64: tlb: Avoid synchronous TLBIs when freeing page tables
By selecting HAVE_RCU_TABLE_INVALIDATE, we can rely on tlb_flush() being
called if we fail to batch table pages for freeing. This in turn allows
us to postpone walk-cache invalidation until tlb_finish_mmu(), which
avoids lots of unnecessary DSBs and means we can shoot down the ASID if
the range is large enough.

James Morse 84c57dbd3c arm64: kernel: arch_crash_save_vmcoreinfo() should depend on CONFIG_CRASH_CORE
Since commit 23c85094fe ("proc/kcore: add vmcoreinfo note to /proc/kcore")
the kernel has exported the vmcoreinfo PT_NOTE on /proc/kcore as well
as /proc/vmcore.

arm64 only exposes it's additional arch information via
arch_crash_save_vmcoreinfo() if built with CONFIG_KEXEC, as kdump was
previously the only user of vmcoreinfo.

Move this weak function to a separate file that is built at the same
time as its caller in kernel/crash_core.c. This ensures values like
'kimage_voffset' are always present in the vmcoreinfo PT_NOTE.

Ard Biesheuvel 7481cddf29 arm64/lib: add accelerated crc32 routines
Unlike crc32c(), which is wired up to the crypto API internally so the
optimal driver is selected based on the platform's capabilities,
crc32_le() is implemented as a library function using a slice-by-8 table
based C implementation. Even though few of the call sites may be
bottlenecks, calling a time variant implementation with a non-negligible
D-cache footprint is a bit of a waste, given that ARMv8.1 and up mandates
support for the CRC32 instructions that were optional in ARMv8.0, but are
already widely available, even on the Cortex-A53 based Raspberry Pi.

So implement routines that use these instructions if available, and fall
back to the existing generic routines otherwise. The selection is based
on alternatives patching.

Note that this unconditionally selects CONFIG_CRC32 as a builtin. Since
CRC32 is relied upon by core functionality such as CONFIG_OF_FLATTREE,
this just codifies the status quo.

Morten Rasmussen 3ba09df4b8 sched/topology, arch/arm64: Rebuild the sched_domain hierarchy when the CPU capacity changes
Asymmetric CPU capacity can not necessarily be determined accurately at
the time the initial sched_domain hierarchy is built during boot. It is
therefore necessary to be able to force a full rebuild of the hierarchy
later triggered by the arch_topology driver. A full rebuild requires the
arch-code to implement arch_update_cpu_topology() which isn't yet
implemented for arm64. This patch points the arm64 implementation to
arch_topology driver to ensure that full hierarchy rebuild happens when
needed.

Marc Zyngier 7d14919c0d arm64: KVM: Only force FPEXC32_EL2.EN if trapping FPSIMD
If trapping FPSIMD in the context of an AArch32 guest, it is critical
to set FPEXC32_EL2.EN to 1 so that the trapping is taken to EL2 and
not EL1.

Conversely, it is just as critical *not* to set FPEXC32_EL2.EN to 1
if we're not going to trap FPSIMD, as we then corrupt the existing
VFP state.

Moving the call to __activate_traps_fpsimd32 to the point where we
know for sure that we are going to trap ensures that we don't set that
bit spuriously.

Mark Rutland fac880c7d0 arm64: fix erroneous warnings in page freeing functions
In pmd_free_pte_page() and pud_free_pmd_page() we try to warn if they
hit a present non-table entry. In both cases we'll warn for non-present
entries, as the VM_WARN_ON() only checks the entry is not a table entry.

This has been observed to result in warnings when booting a v4.19-rc2
kernel under qemu.

Fix this by bailing out earlier for non-present entries.

Ard Biesheuvel 2fffee536c crypto: arm64/crct10dif - implement non-Crypto Extensions alternative
The arm64 implementation of the CRC-T10DIF algorithm uses the 64x64 bit
polynomial multiplication instructions, which are optional in the
architecture, and if these instructions are not available, we fall back
to the C routine which is slow and inefficient.

So let's reuse the 64x64 bit PMULL alternative from the GHASH driver that
uses a sequence of ~40 instructions involving 8x8 bit PMULL and some
shifting and masking. This is a lot slower than the original, but it is
still twice as fast as the current [unoptimized] C code on Cortex-A53,
and it is time invariant and much easier on the D-cache.

Ard Biesheuvel 598b7d41e5 crypto: arm64/crc32 - remove PMULL based CRC32 driver
Now that the scalar fallbacks have been moved out of this driver into
the core crc32()/crc32c() routines, we are left with a CRC32 crypto API
driver for arm64 that is based only on 64x64 polynomial multiplication,
which is an optional instruction in the ARMv8 architecture, and is less
and less likely to be available on cores that do not also implement the
CRC32 instructions, given that those are mandatory in the architecture
as of ARMv8.1.

Since the scalar instructions do not require the special handling that
SIMD instructions do, and since they turn out to be considerably faster
on some cores (Cortex-A53) as well, there is really no point in keeping
this code around so let's just remove it.

Replace the literal load of the addend vector with a sequence that

longer than the original, and 2% faster on Cortex-A53.

This is an improvement by itself, but also works around a Clang issue,
whose integrated assembler does not implement the GNU ARM asm syntax
completely, and does not support the =literal notation for FP registers

The "r_i2c_pins_a" label is renamed to "r_i2c_pl89_pins" to fit our
current style. The node name "i2c" is also changed to "r-i2c-pl89-pins"
to match. The reason for the peculiar name is that the other option for
muxing R_I2C is on the PL0/PL1 pins, so the name has to mention the pin

The eMMC 5.0 standard introduced the data strobe (DS) pin. This pin is
not used for pre-5.0 data modes, nor is it found on pre-5.0 eMMC chips.
On the A64, this pin is muxed with spi0's MISO pin. If the DS pin is
included in the mmc2 pinmux by default, this wil prevent the usage
of both mmc2 and spi0 together.

Instead, split out the DS pin to a separate pinmux that only gets used
by boards that actually have it wired up. Currently supported ones
include the Bananapi M64 and Pine64 Pinebook. These are fixed up.

James Morse f52bb98f5a arm64: mm: always enable CONFIG_HOLES_IN_ZONE
Commit 6d526ee26c ("arm64: mm: enable CONFIG_HOLES_IN_ZONE for NUMA")
only enabled HOLES_IN_ZONE for NUMA systems because the NUMA code was
choking on the missing zone for nomap pages. This problem doesn't just
apply to NUMA systems.

If the architecture doesn't set HAVE_ARCH_PFN_VALID, pfn_valid() will
return true if the pfn is part of a valid sparsemem section.

When working with multiple pages, the mm code uses pfn_valid_within()
to test each page it uses within the sparsemem section is valid. On
most systems memory comes in MAX_ORDER_NR_PAGES chunks which all
have valid/initialised struct pages. In this case pfn_valid_within()

Systems where this isn't true (e.g. due to nomap) should set
HOLES_IN_ZONE and provide HAVE_ARCH_PFN_VALID so that mm tests each

Arnd Bergmann 4faea239e5 y2038: utimes: Rework #ifdef guards for compat syscalls
After changing over to 64-bit time_t syscalls, many architectures will
want compat_sys_utimensat() but not respective handlers for utime(),
utimes() and futimesat(). This adds a new __ARCH_WANT_SYS_UTIME32 to
complement __ARCH_WANT_SYS_UTIME. For now, all 64-bit architectures that
support CONFIG_COMPAT set it, but future 64-bit architectures will not
(tile would not have needed it either, but got removed).

As older 32-bit architectures get converted to using CONFIG_64BIT_TIME,
they will have to use __ARCH_WANT_SYS_UTIME32 instead of
__ARCH_WANT_SYS_UTIME. Architectures using the generic syscall ABI don't
need either of them as they never had a utime syscall.

Since the compat_utimbuf structure is now required outside of
CONFIG_COMPAT, I'm moving it into compat_time.h.

Arnd Bergmann caf6f9c8a3 asm-generic: Remove unneeded __ARCH_WANT_SYS_LLSEEK macro
The sys_llseek sytem call is needed on all 32-bit architectures and
none of the 64-bit ones, so we can remove the __ARCH_WANT_SYS_LLSEEK guard
and simplify the include/asm-generic/unistd.h header further.

Since 32-bit tasks can run either natively or in compat mode on 64-bit
architectures, we have to check for both !CONFIG_64BIT and CONFIG_COMPAT.

There are a few 64-bit architectures that also reference sys_llseek
in their 64-bit ABI (e.g. sparc), but I verified that those all
select CONFIG_COMPAT, so the #if check is still correct here. It's
a bit odd to include it in the syscall table though, as it's the
same as sys_lseek() on 64-bit, but with strange calling conventions.

Arnd Bergmann fb37397594 asm-generic: Move common compat types to asm-generic/compat.h
While converting compat system call handlers to work on 32-bit
architectures, I found a number of types used in those handlers
that are identical between all architectures.

Let's move all the identical ones into asm-generic/compat.h to avoid
having to add even more identical definitions of those types.

For unknown reasons, mips defines __compat_gid32_t, __compat_uid32_t
and compat_caddr_t as signed, while all others have them unsigned.
This seems to be a mistake, but I'm leaving it alone here. The other
types all differ by size or alignment on at least on architecture.

compat_aio_context_t is currently defined in linux/compat.h but
also needed for compat_sys_io_getevents(), so let's move it into
the same place.

While we still have not decided whether the 32-bit time handling
will always use the compat syscalls, or in which form, I think this
is a useful cleanup that we can merge regardless.

Arnd Bergmann 82b355d161 y2038: Remove newstat family from default syscall set
We have four generations of stat() syscalls:
- the oldstat syscalls that are only used on the older architectures
- the newstat family that is used on all 64-bit architectures but
  lacked support for large files on 32-bit architectures.
- the stat64 family that is used mostly on 32-bit architectures to
  replace newstat
- statx() to replace all of the above, adding 64-bit timestamps among
  other things.

We already compile stat64 only on those architectures that need it,
but newstat is always built, including on those that don't reference
it. This adds a new __ARCH_WANT_NEW_STAT symbol along the lines of
__ARCH_WANT_OLD_STAT and __ARCH_WANT_STAT64 to control compilation of
newstat. All architectures that need it use an explict define, the
others now get a little bit smaller, and future architecture (including
64-bit targets) won't ever see it.

Arnd Bergmann 9afc5eee65 y2038: globally rename compat_time to old_time32
Christoph Hellwig suggested a slightly different path for handling
backwards compatibility with the 32-bit time_t based system calls:

Rather than simply reusing the compat_sys_* entry points on 32-bit
architectures unchanged, we get rid of those entry points and the
compat_time types by renaming them to something that makes more sense
on 32-bit architectures (which don't have a compat mode otherwise),
and then share the entry points under the new name with the 64-bit
architectures that use them for implementing the compatibility.

The following types and interfaces are renamed here, and moved
from linux/compat_time.h to linux/time32.h:

old				new
---				---
compat_time_t			old_time32_t
struct compat_timeval		struct old_timeval32
struct compat_timespec		struct old_timespec32
struct compat_itimerspec	struct old_itimerspec32
ns_to_compat_timeval()		ns_to_old_timeval32()
get_compat_itimerspec64()	get_old_itimerspec32()
put_compat_itimerspec64()	put_old_itimerspec32()
compat_get_timespec64()		get_old_timespec32()
compat_put_timespec64()		put_old_timespec32()

As we already have aliases in place, this patch addresses only the
instances that are relevant to the system call interface in particular,
not those that occur in device drivers and other modules. Those
will get handled separately, while providing the 64-bit version
of the respective interfaces.

I'm not renaming the timex, rusage and itimerval structures, as we are
still debating what the new interface will look like, and whether we
will need a replacement at all.

This also doesn't change the names of the syscall entry points, which can
be done more easily when we actually switch over the 32-bit architectures
to use them, at that point we need to change COMPAT_SYSCALL_DEFINEx to
SYSCALL_DEFINEx with a new name, e.g. with a _time32 suffix.

Andre Przywara ca6aee21ce arm64: dts: allwinner: a64: NanoPi-A64: Add Wifi chip
The NanoPi-A64 has an on-board WiFi chip, connected to the usual MMC1 SDIO
interface. The AXP power line is the always-on VDD_SYS_3.3V, but it uses
pin L2 to enable the regulator.
As the actual WiFi driver is not in mainline Linux, it doesn't have a
compatible string, so we omit this from the node.

Add the respective nodes to the DT to make it usable.

Andre Przywara 480f58cdbe arm64: dts: allwinner: a64: NanoPi-A64: Fix DCDC1 voltage
According to the NanoPi-A64 schematics, DCDC1 is connected to a voltage
rail named "VDD_SYS_3.3V". All users seem to expect 3.3V here: the
Ethernet PHY, the uSD card slot, the camera interface and the GPIO pins
on the headers.
Fix up the voltage on the regulator to lift it up to 3.3V.

The Olinuxino has two USB sockets:
USB0 is connected to a micro B socket. As it has the ID pin wired and
the VBUS line connected to the PMIC, we describe it as a proper OTG socket,
which switches between host and device automatically.
USB1 is connected to a normal USB A socket. PG9 enables the power line,
so add the required regulator as well.

Andre Przywara 93366b49a3 arm64: dts: allwinner: a64: Olinuxino: fix DRAM voltage
The Olinuxino board uses DDR3L chips which are supposed to be driven
with 1.35V. The reset default of the AXP is properly set to 1.36V.

While technically the chips can also run at 1.5 volts, changing the
voltage on the fly while booting Linux is asking for trouble. Also
running at a lower voltage saves power.

So fix the DCDC5 value to match the actual board design.

The Orange Pi Win board uses the AXP's ALDO1 power rail to drive the
VCC-CSI line, which, according to the schematic, needs to be set to 2.8V.

Also the ELDO3 power rail is connected to the CSI, with somewhat unclear
voltage requirements. Add this regulator and allow the voltage to be set
between 1.5V and 1.8V, which are the voltages mentioned in the
schematic.
