commit 90444b958461a5f8fc299ece0fe17eab15cba1e1 upstream.
Since its inception the module was meant to be disabled by default, but
the original commit failed to add the relevant property.

commit be08d278eb09210fefbad4c9b27d7843f1c096b2 upstream.
With the introduction of 55c7c0621078 ("ARM: dts: bcm283x: Fix vc4's
firmware bus DMA limitations") the firmware bus has to comply with
/soc's DMA limitations. Ultimately linking both buses to a same
dma-ranges property. The patch (and author) missed the fact that a bus'
#address-cells and #size-cells properties are not inherited, but set to
a fixed value which, in this case, doesn't match /soc's. This, although
not breaking Linux's DMA mapping functionality, generates ugly dtc
warnings.
Fix the issue by adding the correct address and size cells properties
under the firmware bus.

commit f1baca8896ae18e12c45552a4c4ae2086aa7e02c upstream.
512a928affd5 ("ARM: imx: build v7_cpu_resume() unconditionally")
introduced an unintended linker error for i.MX6 configurations that have
ARM_CPU_SUSPEND=n which can happen if neither CONFIG_PM, CONFIG_CPU_IDLE,
nor ARM_PSCI_FW are selected.
Fix this by having v7_cpu_resume() compiled only when cpu_resume() it
calls is available as well.
The C declaration for the function remains unguarded to avoid future code
inadvertently using a stub and introducing a regression to the bug the
original commit fixed.

commit 4141f1a40fc0789f6fd4330e171e1edf155426aa upstream.
In order to wake from suspend by ethernet magic packets the GPC
must be used as intc does not have wakeup functionality.
But the FEC DT node currently uses interrupt-extended,
specificying intc, thus breaking WoL.
This problem is probably fallout from the stacked domain conversion
as intc used to chain to GPC.
So replace "interrupts-extended" by "interrupts" to use the default
parent which is GPC.

commit bb9562cf5c67813034c96afb50bd21130a504441 upstream.
The current arm BPF JIT does not correctly compile RSH or ARSH when the
immediate shift amount is 0. This causes the "rsh64 by 0 imm" and "arsh64
by 0 imm" BPF selftests to hang the kernel by reaching an instruction
the verifier determines to be unreachable.
The root cause is in how immediate right shifts are encoded on arm.
For LSR and ASR (logical and arithmetic right shift), a bit-pattern
of 00000 in the immediate encodes a shift amount of 32. When the BPF
immediate is 0, the generated code shifts by 32 instead of the expected
behavior (a no-op).
This patch fixes the bugs by adding an additional check if the BPF
immediate is 0. After the change, the above mentioned BPF selftests pass.

commit 4178417cc5359c329790a4a8f4a6604612338cca upstream.
This patch fixes an incorrect check in how immediate memory offsets are
computed for BPF_DW on arm.
For BPF_LDX/ST/STX + BPF_DW, the 32-bit arm JIT breaks down an 8-byte
access into two separate 4-byte accesses using off+0 and off+4. If off
fits in imm12, the JIT emits a ldr/str instruction with the immediate
and avoids the use of a temporary register. While the current check off
<= 0xfff ensures that the first immediate off+0 doesn't overflow imm12,
it's not sufficient for the second immediate off+4, which may cause the
second access of BPF_DW to read/write the wrong address.
This patch fixes the problem by changing the check to
off <= 0xfff - 4 for BPF_DW, ensuring off+4 will never overflow.
A side effect of simplifying the check is that it now allows using
negative immediate offsets in ldr/str. This means that small negative
offsets can also avoid the use of a temporary register.
This patch introduces no new failures in test_verifier or test_bpf.c.

Pull ARM DT and driver fixes from Arnd Bergmann:
"For the devicetree files, there are a total of 20 patches, almost
entirely for 32-bit machines:
- The Allwinner/sun9i r40 SoC dtsi file contains a number of issues,
both for correctness and for style that are addressed in separate
patches. This causes most of the changed lines of the DT updates
this time.
- More Allwinner updates fixing the identification of the security
system on sun8i/A33, a recent regression of the A83t ethernet, and
a few board specific issues on the TBS-A711 macine.
- Several bug fixes for OMAP dts files, most notably fixing the
timings for the NAND flash on the Nokia N900 that regressed a while
ago after the move to configuring them from DT. Some other OMAPs
now set the correct dma limits on the L3 bus, and a regression fix
addresses lost Ethernet on dm814x
- One incorrect setting in the newly added Raspberry Pi Zero W that
may cause issues with the SD card controller.
- A missing property on the bcm2835 firmware node caused incorrect
DMA settings.
- An old bug on the oxnas platform causing spurious interrupts is
finally addressed.
- A regression on the Exynos Midas board broke the OLED panel power
supply.
- The i.MX6 phycore SoM specified the wrong voltage for the SoC, this
is now set to the values from the datasheet.
- Some 64-bit machines use a deprecated string to identify the PSCI
firmware.
There are also several small code fixes addressing mostly serious
issues:
- Fix the sunxi rsb bus access to no longer return incorrect data
when mixing 8 and 16 bit I/O.
- Fix a suspend/resume regression on the OMAP2+ lcdc from a missing
quirk in the ti-sysc driver
- Fix a NULL pointer access from a race in the fsl dpio driver
- Fix a v5.5 regression in the exynos-chipid driver that caused an
invalid error code probing the device on non-exynos platforms
- Fix an out-of-bounds access in the AMD TEE driver"

Commit d4ec0cb05064 ("ARM: dts: exynos: Add support for the
touch-sensitive buttons on Midas family") added a new fixed regulator
("voltage-regulator-6") to base "midas" .dtsi, but it didn't update the
clients of that .dtsi, which define their own fixed regulators starting
from the "voltage-regulator-6". This results in aliasing of the regulator
dt nodes and breaks operation of OLED panel due to lack of power supply.
Fix this by increasing the numbers in the fixed regulator names for those
boards.

Looks like we can have the maxtouch touchscreen stop producing interrupts
if an edge interrupt is lost. This can happen easily when the SoC idles as
the gpio controller may not see any state for an edge interrupt if it
is briefly triggered when the system is idle.
Also it looks like maxtouch stops sending any further interrupts if the
interrupt is not handled. And we do have several cases of maxtouch already
configured with a level interrupt, so let's do that.
With level interrupt the gpio controller has the interrupt state visible
after idle. Note that eventually we will probably also be using the
Linux generic wakeirq configured for the controller, but that cannot be
done until the maxtouch driver supports runtime PM.

Add the dma-ranges property to reflect the physical address limit
of the L3 bus.
Issues ere observed only with SATA on DRA7-EVM with 4GB RAM
and CONFIG_ARM_LPAE enabled. This is because the controller
supports 64-bit DMA and its driver sets the dma_mask to 64-bit
thus resulting in DMA accesses beyond L3 limit of 2G.
Setting the correct bus_dma_limit fixes the issue.

location in the device tree file. The device nodes should be sorted
by register address.
Move the devices node to their correct positions within the file.

The current set minimum voltage of 730000µV seems to be wrong. I don't
know the document which specifies that but the imx6qdl datasheets says
that the minimum voltage should be 0.925V for VDD_ARM (LDO bypassed,
lowest opp) and 1.15V for VDD_SOC (LDO bypassed, lowest opp).

Commit a758f50f10cf ("mtd: onenand: omap2: Configure driver from DT")
started using DT specified timings for GPMC, and as a result the
OneNAND stopped working on N900 as we had wrong values in the DT.
Fix by updating the values to bootloader timings that have been tested
to be working on Nokia N900 with OneNAND manufacturers: Samsung,
Numonyx.

commit cf9b5a26876adb266aa1ba8a0b08669389a2e301 in repository:
git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms.git
During the free_pgtables() call all user and modules/pkmap entries are
removed. If a translation fault for the modules/pkmap area occurs before
we switched away from the current pgd, do_translation_fault() would copy
the init_mm pud into the user pud.
There is a small window between pud_clear() and pmd_free_tlb() in
free_pmd_range() where the pud entry was cleared but the TLB has not
been invalidated yet and the CPU may have cached the original (valid)
pud entry in the TLB. A scenario like below would get stuck in
continuous prefetch abort:
1. Current process exiting. The modules pmd entries not populated
2. exit_mmap() -> ... -> pmd_free_tlb()
3. pud_clear() for the 1GB pud containing user stack and modules (no TLB
invalidation yet)
4. Interrupt -> module interrupt routine
5. Level 2 (pmd) translation fault occurs when executing the module
interrupt routine. The CPU previously cached (TLB) the old valid pud
value for the modules area, so we don't get a level 1 translation
fault
6. do_translation fault() copies the pud_k into the pud
7. Linux returns to the faulty instruction. Goes back to 5
At point 7, since the CPU still has the old pud value, it goes back to
point 5 and never gets out of this loop. With this patch, the stale pud
TLB entry is invalidated after point 6 and the subsequent prefetch abort
doesn't occur.

Commit cd28d1d6e52e ("net: phy: at803x: Disable phy delay for RGMII mode")
caused a regression for dm814x boards where NFSroot would no longer work.
Let's fix the issue by configuring "rgmii-id" mode as internal delays are
needed that is no longer the case with "rgmii" mode.
