The "cooling-min-level" and "cooling-max-level" properties are not
parsed by any part of the kernel currently and the max cooling state of
gpio-fan cooling device is found by referring to the
"gpio-fan,speed-map" instead.

Remove the unused properties from the gpio-fan node.

Arnd Bergmann cdcdbbf350 Renesas ARM Based SoC DT Updates for v4.17
* Silk board with R-Car E2 (r8a7794) SoC
   - Add r1ex24002 EEPROM to DT
 
     Magnus Damm says "Extend the Silk board support to include U14 which is
     an I2C based EEPROM hooked up to the I2C1 bus."
 
   - Add GPIO keys to DT
 
     Magnus Damm says "Extend the Silk board support to include SW3, SW4,
     SW6 and SW12. They are all connected via GPIO lines and handled by the
     gpio-keys driver"
 
 * Marzen board with R-Car H1 (r7a7779) SoC
   - Add SDHI0 VCCQ Regulator
 
     Magnus Damm says "Add support for the on-board voltage regulator hooked
     up to GPIO3_20 on r8a7779 Marzen. The board schematics describes the
     regulator as U4 TPS2110A. Input wise, U4 has D0 fixed to ground, D1
     tied to GPIO3_20 while IN1 is fixed to 3.3V and IN2 is fixed to 1.8V.
     OUT goes to the pull-ups for the data pins of SDHI0."
 
 * Porter board with R-Car M3W (r8a7791) SoC
   - Fix HDMI output routing
 
     Laurent Pinchart says "The HDMI encoder is connected to the RGB output
     of the DU, which is port@0, not port@1."
 
 * iWave Systems RZ/G1E SODIMM System On Module (iW-RainboW-G22M-SM) and
   iWave Systems RZ/G1M Qseven System On Module (iW-RainboW-G20M-Qseven)
   - Enable cmt0
 
 * Stout board with R-Car H2 (r8a7790) SoC
   - Initial support
 
 * Lager board with R-Car H2 (r8a7790) SoC
   - Add CEC clock for HDMI transmitter
 
     Niklas Söderlund says "The adv7511 on the Lager board has a 12 MHz
     fixed clock for the CEC block. Specify this in the dts to enable CEC
     support."
 
   - Move cec_clock to root node
 
     By definition nodes without a bus address do not belong on the bus
 
 * kzm9d board with EMMA Mobile EV2 (EMEV2) SoC
   - Fix "debounce-interval" property misspelling
 
 * RZ/G1M (r8a7743) and RZ/G1H (r8a7745) SoCs
   - Add IPMMU DT nodes
   - Add VSP support
 
 * R-Car Gen2 boards
   - Use I2C demuxer for
 
     This allows run-time switching between alternate I2C IP blocks
 
 * R-Car Gen2 and RZ/G1 SoCs
   - Clean up DT files to ease future maintenance
     + add soc node for IP attached to the bus
     + sort subnodes of soc and root node
     + consistently use single space after =
 
 * R-Car H2 (r8a7790), M3-W (r8a7791) and M3-N (r7a7793) SoCs
   - Reduce size of thermal registers
 
     According to the "User's Manual: Hardware" v2.00 the registers at base
     0xe61f0000 extend to an offset of 0x10, rather than 0x14 which is the
     case on the r8a73a4 (R-Mobile APE6).
 
     This should not have any runtime affect as mapping granularity is
     PAGE_SIZE.

Michael Forney a670b0b4ae kbuild: Use ls(1) instead of stat(1) to obtain file size
stat(1) is not standardized and different implementations have their own
(conflicting) flags for querying the size of a file.

ls(1) provides the same information (value of st.st_size) in the 5th
column, except when the file is a character or block device. This output
is standardized[0]. The -n option turns on -l, which writes lines
formatted like

  "%s %u %s %s %u %s %s\n", <file mode>, <number of links>,
      <owner name>, <group name>, <size>, <date and time>,
      <pathname>

but instead of writing the <owner name> and <group name>, it writes the
numeric owner and group IDs (this avoids /etc/passwd and /etc/group
lookups as well as potential field splitting issues).

The <size> field is specified as "the value that would be returned for
the file in the st_size field of struct stat".

To avoid duplicating logic in several locations in the tree, create
scripts/file-size.sh and update callers to use that instead of stat(1).

Leonard Crestez 6aaf49b495 crypto: arm,arm64 - Fix random regeneration of S_shipped
The decision to rebuild .S_shipped is made based on the relative
timestamps of .S_shipped and .pl files but git makes this essentially
random. This means that the perl script might run anyway (usually at
most once per checkout), defeating the whole purpose of _shipped.

Fix by skipping the rule unless explicit make variables are provided:
REGENERATE_ARM_CRYPTO or REGENERATE_ARM64_CRYPTO.

This can produce nasty occasional build failures downstream, for example
for toolchains with broken perl. The solution is minimally intrusive to
make it easier to push into stable.

Marc Zyngier 33625282ad irqchip/gic-v3: Probe for SCR_EL3 being clear before resetting AP0Rn
We would like to reset the Group-0 Active Priority Registers
at boot time if they are available to us. They would be available
if SCR_EL3.FIQ was not set, but we cannot directly probe this bit,
and short of checking, we may end-up trapping to EL3, and the
firmware may not be please to get such an exception. Yes, this
is dumb.

Instead, let's use PMR to find out if its value gets affected by
SCR_EL3.FIQ being set. We use the fact that when SCR_EL3.FIQ is
set, the LSB of the priority is lost due to the shifting back and
forth of the actual priority. If we read back a 0, we know that
Group0 is unavailable. In case we read a non-zero value, we can
safely reset the AP0Rn register.

Marek Szyprowski a7480dbcf9 ARM: EXYNOS: Fix coupled CPU idle freeze on Exynos4210
Since commit 04c8b0f82c ("irqchip/gic: Make locking a BL_SWITCHER only
feature") coupled CPU idle freezes from time to time on Exynos4210. Later
commit 313c8c16ee ("PM / CPU: replace raw_notifier with atomic_notifier")
changed the context in which the CPU idle code is executed, what results
in fully reproducible freeze all the time. However, almost the same coupled
CPU idle code works fine on Exynos3250 regardless of the changes made in
the mentioned commits.

It turned out that the IPI call used on Exynos4210 is conflicting with the
change done in the first mentioned commit in GIC. Fix this by using the

Tony Lindgren eb85a355c3 ARM: OMAP: Fix SRAM W+X mapping
We are still using custom SRAM code for some SoCs and are not marking
the PM code mapped to SRAM as read-only and executable after we're
done. With CONFIG_DEBUG_WX=y, we will get "Found insecure W+X mapping
at address" warning.

Let's fix this issue the same way as commit 728bbe75c8 ("misc: sram:
Introduce support code for protect-exec sram type") is doing for
drivers/misc/sram-exec.c.

On omap3, we need to restore SRAM when returning from off mode after
idle, so init time configuration is not enough.

And as we no longer have users for omap_sram_push_address() we can
make it static while at it.

Note that eventually we should be using sram-exec.c for all SoCs.

Martin Blumenstingl 4e461e62fc ARM: dts: meson8b: the CBUS GPIO controller only has 83 GPIOs
Update the "gpio-ranges" property of the CBUS GPIO controller on Meson8b
because it only provides 83 GPIOs.
The GPIO definitions in include/dt-bindings/gpio/meson8b-gpio.h
inherited all GPIOs from Meson8 until recently. However, Meson8b does
not support all GPIOs which are supported by Meson8 (Meson8b doesn't
have a GPIOZ bank, most of the pins from the GPIODV bank are missing on
Meson8b - just to name a few differences).

The actual number of GPIOs is only 83, instead of 120 from Meson8 plus
the 10 GPIOs from the DIF bank on Meson8b.

to userspace. Define that bit 28 in this encoding indicates secure vs
nonsecure, so we can distinguish the secure and nonsecure banked versions
of a banked AArch32 register.

For KVM currently, all guest registers are nonsecure, but defining
the bit is useful for userspace. In particular, QEMU uses this
encoding as part of its on-the-wire migration format, and needs to be

Marc Zyngier dc2e4633ff arm/arm64: KVM: Introduce EL2-specific executable mappings
Until now, all EL2 executable mappings were derived from their
EL1 VA. Since we want to decouple the vectors mapping from
the rest of the hypervisor, we need to be able to map some
text somewhere else.

The "idmap" region (for lack of a better name) is ideally suited
for this, as we have a huge range that hardly has anything in it.

Let's extend the IO allocator to also deal with executable mappings,
thus providing the required feature.

Marc Zyngier e3f019b37b KVM: arm/arm64: Move HYP IO VAs to the "idmap" range
We so far mapped our HYP IO (which is essentially the GICv2 control
registers) using the same method as for memory. It recently appeared
that is a bit unsafe:

We compute the HYP VA using the kern_hyp_va helper, but that helper
is only designed to deal with kernel VAs coming from the linear map,
and not from the vmalloc region... This could in turn cause some bad
aliasing between the two, amplified by the upcoming VA randomisation.

A solution is to come up with our very own basic VA allocator for
MMIO. Since half of the HYP address space only contains a single
page (the idmap), we have plenty to borrow from. Let's use the idmap
as a base, and allocate downwards from it. GICv2 now lives on the
other side of the great VA barrier.

Marc Zyngier 1bb32a44ae KVM: arm/arm64: Keep GICv2 HYP VAs in kvm_vgic_global_state
As we're about to change the way we map devices at HYP, we need
to move away from kern_hyp_va on an IO address.

One way of achieving this is to store the VAs in kvm_vgic_global_state,
and use that directly from the HYP code. This requires a small change
to create_hyp_io_mappings so that it can also return a HYP VA.

We take this opportunity to nuke the vctrl_base field in the emulated
distributor, as it is not used anymore.

Both HYP io mappings call ioremap, followed by create_hyp_io_mappings.
Let's move the ioremap call into create_hyp_io_mappings itself, which

Marc Zyngier 44a497abd6 KVM: arm/arm64: Do not use kern_hyp_va() with kvm_vgic_global_state
kvm_vgic_global_state is part of the read-only section, and is
usually accessed using a PC-relative address generation (adrp + add).

It is thus useless to use kern_hyp_va() on it, and actively problematic
if kern_hyp_va() becomes non-idempotent. On the other hand, there is
no way that the compiler is going to guarantee that such access is
always PC relative.

So let's bite the bullet and provide our own accessor.

Christoffer Dall 2d0e63e030 KVM: arm/arm64: Avoid VGICv3 save/restore on VHE with no IRQs
We can finally get completely rid of any calls to the VGICv3
save/restore functions when the AP lists are empty on VHE systems.  This
requires carefully factoring out trap configuration from saving and
restoring state, and carefully choosing what to do on the VHE and
non-VHE path.

One of the challenges is that we cannot save/restore the VMCR lazily
because we can only write the VMCR when ICC_SRE_EL1.SRE is cleared when
emulating a GICv2-on-GICv3, since otherwise all Group-0 interrupts end
up being delivered as FIQ.

To solve this problem, and still provide fast performance in the fast
path of exiting a VM when no interrupts are pending (which also
optimized the latency for actually delivering virtual interrupts coming
from physical interrupts), we orchestrate a dance of only doing the
activate/deactivate traps in vgic load/put for VHE systems (which can
have ICC_SRE_EL1.SRE cleared when running in the host), and doing the
configuration on every round-trip on non-VHE systems.

Christoffer Dall 923a2e30e5 KVM: arm/arm64: Move VGIC APR save/restore to vgic put/load
The APRs can only have bits set when the guest acknowledges an interrupt
in the LR and can only have a bit cleared when the guest EOIs an
interrupt in the LR.  Therefore, if we have no LRs with any
pending/active interrupts, the APR cannot change value and there is no
need to clear it on every exit from the VM (hint: it will have already
been cleared when we exited the guest the last time with the LRs all
EOIed).

The only case we need to take care of is when we migrate the VCPU away
from a CPU or migrate a new VCPU onto a CPU, or when we return to
userspace to capture the state of the VCPU for migration.  To make sure
this works, factor out the APR save/restore functionality into separate
functions called from the VCPU (and by extension VGIC) put/load hooks.

Since this file also no longer saves/restores anything, rename the file

Christoffer Dall 00536ec476 KVM: arm/arm64: Prepare to handle deferred save/restore of SPSR_EL1
SPSR_EL1 is not used by a VHE host kernel and can be deferred, but we
need to rework the accesses to this register to access the latest value

The handling of accessing the various banked SPSRs for 32-bit VMs is a
bit clunky, but this will be improved in following patches which will
first prepare and subsequently implement deferred save/restore of the
32-bit registers, including the 32-bit SPSRs.

The only difference after this patch between the VHE and non-VHE run

Arnd Bergmann 0240f30721 i.MX SoC changes for 4.17:
- Add i.MX 6SoloLiteLite (i.MX6SLL) SoC support on top of the existing
    i.MX6SL platform code.
  - Improve the SoC revision mapping by utilizing the MAJOR field of
    ANATOP DIGPROG register.
  - Add CPUIDLE_FLAG_TIMER_STOP flag for cpuidle ARM power off state,
    so that we can use ARM generic timer for some i.MX6 SoC.
  - Set low-power interrupt mask for i.MX25 to support STOP mode.
  - Drop EPIT driver as there is no user of it.
  - Simplify the error path of imx6_pm_get_base() a bit.

Updates to OpenPower BMC systems:
 
  A number of updates to use recently merged drivers, including moving to
  upstreamed IPMI BT nodes, a temp sensor for Romulus, and adding
  simple-reset for UARTs.
 
  This includes more of Palmetto's device tree, so that it's ever so

Marc Zyngier d6062a6d62 irqchip/gic-v3: Reset APgRn registers at boot time
Booting a crash kernel while in an interrupt handler is likely
to leave the Active Priority Registers with some state that
is not relevant to the new kernel, and is likely to lead
to erratic behaviours such as interrupts not firing as their
priority is already active.

As a sanity measure, wipe the APRs clean on startup. We make
sure to wipe both group 0 and 1 registers in order to avoid
any surprise.

Joel Stanley 9bdc00a5c1 ARM: dts: aspeed: Add default memory node
When we removed the inclusion of skeleton.dtsi from the device trees, we
broke booting for systems with bootloaders that aren't device tre aware.
This can be seen, for example, when appending the device tree blob to
the kernel image.

The reason booting broke was that the kernel lacked the device_type
label in the memory node. Add in a default memory node wth the
device_type. It can contain the memory address as the location is fixed
for each SoC generation, but the size needs to be added by the
bootloader or the board specific dts.

Fabrizio Castro 58adf1ba0d ARM: shmobile: Add watchdog support
On R-Car Gen2 and RZ/G1 platforms, we use the SBAR registers to make non
boot CPUs run a routine designed to bring up SMP and deal with hot plug.
The value contained in the SBAR registers is not initialized by a WDT
triggered reset, which means that after a WDT triggered reset we jump
to the SMP bring up routine, preventing the system from executing the
bootrom code.

The purpose of this patch is to jump to the bootrom code in case of a
WDT triggered reset, and keep the SMP functionality untouched.
In order to tell if the code had been called due to the WDT overflowing
we are testing WOVF from register RWTCSRA.

The new function shmobile_boot_vector_gen2 isn't replacing
shmobile_boot_vector for backward compatibility reasons. The kernel
will install the best option (either shmobile_boot_vector or
shmobile_boot_vector_gen2) to ICRAM1 after parsing the device tree,
according to the amount of memory available.

Since shmobile_boot_vector has become bigger, "reg" property of nodes
compatible with "renesas,smp-sram" now need to be set to a value
greater or equal to "<0 0x60>".

Now that we have added support for pre-pended Broadcom tags with commit
1160603960 ("net: dsa: b53: Support prepended Broadcom tags") we can
switch all the Northstar Plus reference boards to use port 8 for the CPU
port. This allows us to prepare room for supporting the Flow Accelerator
2 NAPT offload, and frees up port 5 to be made fully configurable for
the modes that it supports: internal, SGMII, RGMII etc.

Sebastian Reichel 3c6b4f46b4 ARM: dts: omap3-n900: Add link between battery and charger
This adds information, that the battery is charged by the charger.
The Linux kernel uses this information to refresh battery information
when the power-supply changes.

Sean Wang 0629a01920 arm: dts: mt7623: fix USB initialization fails on bananapi-r2
Fix that USB initialization fails as below runtime log is present during
booting on bananapi-r2 board by adding missing regulators the USB device
requires. Current regulators USB device uses are being updated with the
correct ones to reflect real configurations which are all from fixed
regulators rather than MT6323 one's output.

ARM: dts: sun8i: reference tablet design: Enable PMIC power supplies
The A23/A33 reference tablet design has a DC barrel tied to the ACIN
of the PMIC. And being a tablet, it has a Li-Po battery.

Enable both power supplies in the device tree.

ARM: dts: sun8i: a33: Enable A33 internal audio codec on A33-OLinuXino
The A33-OLinuXino routes the SoC's headphone output to a headphone jack,
and the microphone input to a microphone jack. Power to the microphone
is provided by MBIAS.

This patch enables the various parts of the codec, and adds widgets and
routes for simple-card.

HBIAS is connected to the microphone jack as well, but in a manner that
is confusing and likely does not provide power. This part is left out
of this patch.
