The symbols can no longer be used as loadable modules, leading to a harmless Kconfig
warning:

Roger Shimizu 6cfd3cd8d8 ARM: dts: orion5x-lschl: More consistent naming on linkstation series
DTS files, which includes orion5x-linkstation.dtsi, are named:
  orion5x-linkstation-*.dts

So we rename the file below:
  arch/arm/boot/dts/orion5x-lschl.dts
to the new name:
  arch/arm/boot/dts/orion5x-linkstation-lschl.dts

Because DTS conversion of this device was just introduced in 4.9, Debian
is still using legacy device support, other distros are the same,
so here we won't expect any impact actually.

Fabio Estevam a971c5545c ARM: dts: imx: Pass 'chosen' and 'memory' nodes
Commit 7f107887d1 ("ARM: dts: imx: Remove skeleton.dtsi") causes boot
issues when the bootloader does not create a 'chosen' node if such node
is not present in the dtb.

The reason for the boot failure is well explained by Javier Martinez
Canillas: "the decompressor relies on a pre-existing chosen node to be
available to insert the command line and merge other ATAGS info."

, so pass an empty 'chosen' node to fix the boot problem.

This issue has been seen in the kernelci reports with Barebox as
bootloader.

Also pass the 'memory' node in order to fix boot issues on the SolidRun
iMX6 platforms.

GPIO4_11 is on pin 152(MX6DL_PAD_KEY_ROW2) and not on pin

I found the error while booting a mainline kernel on APF6S SoM and

Fabien Parent 43849785e1 ARM: dts: da850-evm: fix read access to SPI flash
Read access to the SPI flash are broken on da850-evm, i.e. the data
read is not what is actually programmed on the flash.
According to the datasheet for the M25P64 part present on the da850-evm,
if the SPI frequency is higher than 20MHz then the READ command is not
usable anymore and only the FAST_READ command can be used to read data.

This commit specifies in the DTS that we should use FAST_READ command
instead of the READ command.

Linus Walleij 90f92c631b ARM: 8613/1: Fix the uaccess crash on PB11MPCore
The following patch was sketched by Russell in response to my
crashes on the PB11MPCore after the patch for software-based
priviledged no access support for ARMv8.1. See this thread:
http://marc.info/?l=linux-arm-kernel&m=144051749807214&w=2

I am unsure what is going on, I suspect everyone involved in
the discussion is. I just want to repost this to get the
discussion restarted, as I still have to apply this patch
with every kernel iteration to get my PB11MPCore Realview
running.

Testing by Neil Armstrong on the Oxnas NAS has revealed that
this bug exist also on that widely deployed hardware, so
we are probably currently regressing all ARM11MPCore systems.

Jean-Jacques Hiblot 87cb12910a ARM: dts: OMAP5 / DRA7: indicate that SATA port 0 is available.
AHCI provides the register PORTS_IMPL to let the software know which port
is supported. The register must be initialized by the bootloader. However
in some cases u-boot doesn't properly initialize this value (if it is not
compiled with SATA support for example or if the SATA initialization fails).
The DTS entry "ports-implemented" can be used to override the value in
PORTS_IMPL.

Without this patch the SATA will not work in the following two cases:

* if there has been a failure to initialize SATA in u-boot.

* if ahci_platform module has been removed and re-inserted. The reason is
  that the content of PORTS_IMPL is lost after the module is removed.
  I suspect that it's because the controller is reset by the hwmod.

Nicolas Dichtel ed79c9d34f ARM: put types.h in uapi
Due to the way kbuild works, this header was unintentionally exported
back in 2013 when it was created, despite it not being in a uapi/
directory.  This is very non-intuitive behaviour by Kbuild.

However, we've had this include exported to userland for almost four
years, and searching google for "ARM types.h __UINTPTR_TYPE__" gives
no hint that anyone has complained about it.  So, let's make it
officially exported in this state.

Jintack Lim 488f94d721 KVM: arm64: Access CNTHCTL_EL2 bit fields correctly on VHE systems
Current KVM world switch code is unintentionally setting wrong bits to
CNTHCTL_EL2 when E2H == 1, which may allow guest OS to access physical
timer.  Bit positions of CNTHCTL_EL2 are changing depending on
HCR_EL2.E2H bit.  EL1PCEN and EL1PCTEN are 1st and 0th bits when E2H is
not set, but they are 11th and 10th bits respectively when E2H is set.

In fact, on VHE we only need to set those bits once, not for every world
switch. This is because the host kernel runs in EL2 with HCR_EL2.TGE ==
1, which makes those bits have no effect for the host kernel execution.
So we just set those bits once for guests, and that's it.

Mark Rutland ddc37832a1 ARM: 8634/1: hw_breakpoint: blacklist Scorpion CPUs
On APQ8060, the kernel crashes in arch_hw_breakpoint_init, taking an
undefined instruction trap within write_wb_reg. This is because Scorpion
CPUs erroneously appear to set DBGPRSR.SPD when WFI is issued, even if
the core is not powered down. When DBGPRSR.SPD is set, breakpoint and
watchpoint registers are treated as undefined.

It's possible to trigger similar crashes later on from userspace, by
requesting the kernel to install a breakpoint or watchpoint, as we can
go idle at any point between the reset of the debug registers and their
later use. This has always been the case.

Given that this has always been broken, no-one has complained until now,
and there is no clear workaround, disable hardware breakpoints and
watchpoints on Scorpion to avoid these issues.

Rabin Vincent 270c8cf1ca ARM: 8632/1: ftrace: fix syscall name matching
ARM has a few system calls (most notably mmap) for which the names of
the functions which are referenced in the syscall table do not match the
names of the syscall tracepoints.  As a consequence of this, these
tracepoints are not made available.  Implement
arch_syscall_match_sym_name to fix this and allow tracing even these
system calls.

Emmanuel Vadot 3116d37651 ARM: dts: sunxi: Change node name for pwrseq pin on Olinuxino-lime2-emmc
The node name for the power seq pin is mmc2@0 like the mmc2_pins_a one.
This makes the original node (mmc2_pins_a) scrapped out of the dtb and
result in a unusable eMMC if U-Boot didn't configured the pins to the
correct functions.

Chen-Yu Tsai 205ac7b33e ARM: dts: sun6i: Disable display pipeline by default
While we now support the internal display pipeline found on sun6i, it
is possible that we are unable to enable the display for some boards,
due to a lack of drivers for the panels or bridges found on them. If
the display pipeline is enabled, the driver will try to enable, and
possibly screw up the simple framebuffer U-boot had configured.

Disable the display pipeline by default.

Gary Bisson 37530e7460 ARM: dts: imx6qdl-nitrogen6_som2: fix sgtl5000 pinctrl init
Since the codec is probed first, the pinctrl node should be
under the codec node.

The codec init was working for this board since U-Boot was
already setting GPIO_0 as CLKO1 but better fix it anyway.

This patch fixes the following error:

imx-sgtl5000 sound: ASoC: CODEC DAI sgtl5000 not registered
imx-sgtl5000 sound: snd_soc_register_card failed (-517)

The problem was that the pinctrl group was linked to the sound driver
instead of the codec node. Since the codec is probed first, the sys_mclk
was missing and it would therefore fail to initialize.

Peter Ujfalusi 657279778a ARM: OMAP1: DMA: Correct the number of logical channels
OMAP1510, OMAP5910 and OMAP310 have only 9 logical channels.
OMAP1610, OMAP5912, OMAP1710, OMAP730, and OMAP850 have 16 logical channels
available.

The wired 17 for the lch_count must have been used to cover the 16 + 1
dedicated LCD channel, in reality we can only use 9 or 16 channels.

The d->chan_count is not used by the omap-dma stack, so we can skip the
setup. chan_count was configured to the number of logical channels and not
the actual number of physical channels anyways.
