Pull ARM SoC fixes from Olof Johansson:
"Final batch of SoC fixes
A few fixes that have trickled in over the last week, all fixing minor
errors in devicetrees -- UART pin assignment on Allwinner H3,
correcting number of SATA ports on a Marvell-based Linkstation
platform and a display clock fix for Freescale/NXP i.MX7D that fixes a
freeze when starting up X"

Bug report from Debian [0] shows there's minor changed model of
Linkstation LS-GL that uses the 2nd SATA port of the SoC.
So it's necessary to enable two SATA ports, though for that specific
model only the 2nd one is used.

The eLCDIF IP of the i.MX 7 SoC knows multiple clocks and lists them
separately:
Clock Clock Root Description
apb_clk MAIN_AXI_CLK_ROOT AXI clock
pix_clk LCDIF_PIXEL_CLK_ROOT Pixel clock
ipg_clk_s MAIN_AXI_CLK_ROOT Peripheral access clock
All of them are switched by a single gate, which is part of the
IMX7D_LCDIF_PIXEL_ROOT_CLK clock. Hence using that clock also for
the AXI bus clock (clock-name "axi") makes sure the gate gets
enabled when accessing registers.
There seem to be no separate AXI display clock, and the clock is
optional. Hence remove the dummy clock.
This fixes kernel freezes when starting the X-Server (which
disables/re-enables the display controller).

In a previous commit, I made a copy/paste error in the pinmux
definitions of UART3: PG{13,14} instead of PA{13,14}. This commit takes
care of that. I have tested this commit on Orange Pi PC and Orange Pi
Plus, and it works for these boards.

Pull ARM SoC fixes from Arnd Bergmann:
"This should be the last set of bugfixes for arm-soc in v4.9. None of
these are critical regressions, but it would be nice to still get them
merged.
- On the Juno platform, the idle latency was described wrong, leading
to suboptimal cpuidle tuning.
- Also on the same platform, PCI I/O space was set up incorrectly and
could not work.
- On the sti platform, a syntactically incorrect DT entry caused
warnings.
- The newly added 'gr8' platform has somewhat confusing file names,
which we rename for consistency"

This reverts commit 4dd1837d7589f468ed109556513f476e7a7f9121.
Moving the exports for assembly code into the assembly files breaks
KSYM trimming, but also breaks modversions.
While fixing the KSYM trimming is trivial, fixing modversions brings
us to a technically worse position that we had prior to the above
change:
- We end up with the prototype definitions divorsed from everything
else, which means that adding or removing assembly level ksyms
become more fragile:
* if adding a new assembly ksyms export, a missed prototype in
asm-prototypes.h results in a successful build if no module in
the selected configuration makes use of the symbol.
* when removing a ksyms export, asm-prototypes.h will get forgotten,
with armksyms.c, you'll get a build error if you forget to touch
the file.
- We end up with the same amount of include files and prototypes,
they're just in a header file instead of a .c file with their
exports.
As for lines of code, we don't get much of a size reduction:
(original commit)
47 files changed, 131 insertions(+), 208 deletions(-)
(fix for ksyms trimming)
7 files changed, 18 insertions(+), 5 deletions(-)
(two fixes for modversions)
1 file changed, 34 insertions(+)
3 files changed, 7 insertions(+), 2 deletions(-)
which results in a net total of only 25 lines deleted.
As there does not seem to be much benefit from this change of approach,
revert the change.

Commit 7619751f8c90 ("ARM: 8595/2: apply more __ro_after_init") caused
a regression with XIP kernels by moving the __ro_after_init data into
the read-only section. With XIP kernels, the read-only section is
located in read-only memory from the very beginning.
Work around this by moving the __ro_after_init data back into the .data
section, which will be in RAM, and hence will be writable.
It should be noted that in doing so, this remains writable after init.

fs_initcall is definitely too late to initialize DMA-debug hash tables,
because some drivers might get probed and use DMA mapping framework
already in core_initcall. Late initialization of DMA-debug results in
false warning about accessing memory, that was not allocated, like this
one:

This patch moves initialization of DMA-debug to core_initcall. This is
safe from the initialization perspective. dma_debug_do_init() internally calls
debugfs functions and debugfs also gets initialised at core_initcall(), and
that is earlier than arch code in the link order, so it will get initialized
just before the DMA-debug.

Recent kernels have changed their behaviour to be more inconsistent
when handling printk continuations. With todays kernels, the output
looks sane on the console, but dmesg splits individual printk()s which
do not have the KERN_CONT prefix into separate lines.
Since the assembly code is not trivial to add the KERN_CONT, and we
ideally want to avoid using KERN_CONT (as multiple printk()s can race
between different threads), convert the assembly dumping the register
values to C code, and have the C code build the output a line at a
time before dumping to the console.
This avoids the KERN_CONT issue, and also avoids situations where the
output is intermixed with other console activity.

without them, the pinmux cannot be initialized, and the uart cannot
be used.
Add them back to fix the problem, and makes the bluetooth on iNet D978

Fixes for omaps for v4.9-rc cycle. Except for the omap3 fix for the SoC
features printed, all these are quite trivial and tiny. The omap5 jack
detection and gpadc patches are not strictly fixes, but I wanted to get
binding document typo fixed before it pops up on other boards. The
gpadc one liner was in the same series and I applied and pushed it out
already before noticing it could have waited. The list of changes is:
- Fix omap3 SoC features printed
- Make sure OMAP_INTERCONNECT is selected for am43xx only configurations
- Add missing memory node for torpedo
- Initialize uart4_mask properly to avoid writing garbage to PRM registers
- Fix NULL pointer dereference for omap4 volt_data
- Add alias for omap5 gpadc needed by iio drivers
- Enable omap5 jack headset jack detection and fix it's binding typo
- Add missing memory node for logicpd-som-lv

DDR3L is usually specified as
JEDEC standard 1.35V(1.28V~1.45V) & 1.5V(1.425V~1.575V)
Therefore setting smps6 regulator to 1.2V is definitively below
minimum. It appears that real world chips are more forgiving than
data sheets indicate, but let's set the regulator right.
Note: a board that uses other voltages (DDR with 1.5V) can
overwrite by referencing &smps6_reg.

The skeleton.dtsi file was removed in ARM64 for different reasons as
explained in commit ("3ebee5a2e141 arm64: dts: kill skeleton.dtsi").
commit ("766a1fe78fc3 ARM: omap3: Add missing memory node") had
fixes for Torpedo and Overo boards, but this SOM-LV was missed.
This should help prevent the DTC warning:
"Node /memory has a reg or ranges property, but no unit name"

For OMAP4, volt_data is set in omap44xx_voltagedomains_init.
If the SoC is neither OMAP443X or OMAP446X, we end up with a
NULL in volt_data which causes a kernel oops.
This is the case when booting OMAP4470.

In the case where has_uart4 is false, en_uart4_mask and grpsel_uart4_mask
are not initialized and so any garbage value is being logically or'd into
the write of PM_WKEN and OMAP3430_PM_MPUGRPSEL. Fix this by initializing
these masks to zero.

With the printk cleanups merged into v4.9-rc1, we now get the omap
revision printed on multiple lines. Let's fix that and also remove the
extra empty space at the end of the features. And let's update things
to use scnprintf as suggested by Ivaylo Dimitrov
<ivo.g.dimitrov.75@gmail.com>.

KVM/ARM updates for v4.9-rc4
- Kick the vcpu when a pending interrupt becomes pending again
- Prevent access to invalid interrupt registers
- Invalid TLBs when two vcpus from the same VM share a CPU

single CPU
Architecturally, TLBs are private to the (physical) CPU they're
associated with. But when multiple vcpus from the same VM are
being multiplexed on the same CPU, the TLBs are not private
to the vcpus (and are actually shared across the VMID).
Let's consider the following scenario:
- vcpu-0 maps PA to VA
- vcpu-1 maps PA' to VA
If run on the same physical CPU, vcpu-1 can hit TLB entries generated
by vcpu-0 accesses, and access the wrong physical page.
The solution to this is to keep a per-VM map of which vcpu ran last
on each given physical CPU, and invalidate local TLBs when switching
to a different vcpu from the same VM.

this by making the abort handler save and restore R9.

Nothing sticks out as particularly bad or scary, it's mostly a handful

changes could probably have been delayed to 4.10, but they're not
scary and just plumbing up driver changes that went in during the

The global timer IRQ (PPI[0], PPI 11 in device tree terms) is a
rising edge interrupt. The ARM Cortex-A5 MPCore TRM in Chapter
10.1.2. Interrupt types and sources says:
"Interrupt is rising-edge sensitive."
The bits seem to be read-only, hence this missconfiguration had
no negative effect. However, with commit 992345a58e0c
("irqchip/gic: WARN if setting the interrupt type for a PPI fails")
warnings such as this get printed:
GIC: PPI11 is secure or misconfigured
With this change the new configuration matches the default
configuration and no warning is printed anymore.

Instead of returning of_genpd_add_provider_onecell() directly,
we should check its return value and in the case of error we
should unwind the previously taken actions, which in these case are:
- Call imx6q_pm_pu_power_off()
- Set imx6q_pu_domain.reg back to NULL
Setting imx6q_pu_domain.reg to NULL in the error case is important
as it will prevent further operations in the pu_reg regulator.
This kernel crash is not observed with imx_v6_v7_defconfig because
it selects GPU and VPU drivers, which are consumers of the GPC block
and thus change the refcount of the pu_reg regulator.

Since commit 0159ec670763dd ("PM / Domains: Verify the PM domain is present
when adding a provider") the following regression is observed on imx6:
imx-gpc: probe of 20dc000.gpc failed with error -22
The gpc probe fails because of_genpd_add_provider_onecell() now checks
if all the domains are initialized via pm_genpd_present() function
and it fails because not all the power domains are initialized.
In order to fix this error, initialize all the power domains from
imx_gpc_domains[], not only the imx6q_pu_domain.base one.

I made a mistake bacuse the Media I/O block is not implemented in
these SoCs.

This fixes a very annoying regression on the Snowball SD card
that has been around for a while. It turns out that the device
tree does not configure the direction pins properly, nor sets
up the pins for the voltage converter properly at boot. Unless
all things are correctly set up, the feedback clock will not
work, and makes the driver spew messages in the console (but
it works, very slowly):
root@Ux500:/ mount /dev/mmcblk0p2 /mnt/
[ 9.953460] mmci-pl18x 80126000.sdi0_per1: error during DMA transfer!
[ 9.960296] mmcblk0: error -110 sending status command, retrying
[ 9.966461] mmcblk0: error -110 sending status command, retrying
[ 9.972534] mmcblk0: error -110 sending status command, aborting
Fix this by rectifying the device tree to correspond to that of
the Ux500 HREF boards plus the DAT31DIR setting that is unique for
the Snowball, and things start working smoothly. Add in the SDR12
and SDR25 modes which this host can do without any problems.
I don't know if this has ever been correct, sadly. It works after
this patch.

mvebu fixes for 4.8 (part 3)

Since the commit bd3677ff31a3 ("clk: mvebu: Remove corediv clock from
Armada XP"), the corediv clk is no more selected for Armada XP, however
this clock is used for Armada XP using the compatible
armada-370-corediv-clock.
While since commit 1594d568c6e3 ("clk: mvebu: Move corediv config to
mvebu config") Armada 38x and Armada 375 got corediv support again, not
only Armada XP was missed but also Armada 39x.
Actually all the SoC selecting MVEBU_V7 config need this clock:
git grep "\-corediv-clock" arch/arm/boot/dts
arch/arm/boot/dts/armada-370-xp.dtsi: compatible = "marvell,armada-370-corediv-clock";
arch/arm/boot/dts/armada-375.dtsi: compatible = "marvell,armada-375-corediv-clock";
arch/arm/boot/dts/armada-38x.dtsi: compatible = "marvell,armada-380-corediv-clock";
arch/arm/boot/dts/armada-39x.dtsi: compatible = "marvell,armada-390-corediv-clock"
This commit now fixes this behavior by letting MVEBU_V7 select
MVEBU_CLK_COREDIV.
