1ac19c8b7f ARM: dts: DRA74x: Use PCIe compatible specific to dra74
Use dra74 specific compatible string for PCIe while preserving
the older compatible. While at that add a new label for the
2nd instance of pcie.

337c6c9a69 ARM: dts: am437x-idk-evm: Disable OPP50 for MPU
AM437x IDK has a TPS386000 supply voltage supervisor on the VDD_MPU rail
set to trigger undervoltage condition at 0.96V. Because of this, OPP50,
which is normally configured to 300MHz at 0.95V, must be disabled to
avoid triggering the undervoltage condition. Also mark OPP100 as the
suspend-opp as it is now our lowest OPP.

Due to a mistake in documentation the DS0_PULL_UP_DOWN_EN macro was
mistakenly defined as an active high bit, however setting the bit

9b490b3db5 ARM: dts: am3/am4/dra7/omap: Remove leading 0x and 0s from bindings notation
Improve the DTS files by removing all the leading "0x" and zeros to fix the
following dtc warnings:

Warning (unit_address_format): Node /XXX unit name should not have
leading "0x"

and

Warning (unit_address_format): Node /XXX unit name should not have
leading 0s

Converted using the following command:

$ find . -type f \( -iname *.dts -o -iname *.dtsi \) -exec \
sed -i -e "s/@\([0-9a-fA-FxX\.;:#]+\)\s*{/@\L\1 {/g" \
-e "s/@0x\(.*\) {/@\1 {/g" -e "s/@0+\(.*\) {/@\1 {/g" {} +^C

For simplicity, two sed expressions were used to solve each warnings
separately.

To make the regex expression more robust a few other issues were resolved,
namely setting unit-address to lower case, and adding a whitespace before
the the opening curly brace:

https://elinux.org/Device_Tree_Linux#Linux_conventions

This will solve as a side effect warning:

Warning (simple_bus_reg): Node /XXX@<UPPER> simple-bus unit address format
error, expected "<lower>"

This is a follow up to commit 4c9847b737 ("dt-bindings: Remove leading
0x from bindings notation")

b8c9c6fa20 ARM: dts: dra7: Disable USB metastability workaround for USB2
The metastability workaround causes Erratic errors [1]
on the HighSpeed USB PHY which can cause upto 2 seconds
delay in enumerating to a USB host while in Gadget mode.

Disable the Run/Stop metastability workaround to avoid this
ill effect. We are aware that this opens up the opportunity
for Run/Stop metastability, however this issue has never been
observed in TI releases so we think that Run/Stop metastability
is a lesser evil than the PHY Erratic errors. So disable it.

cf87634c8b ARM: dts: Fix omap4 hang with GPS connected to USB by using wakeupgen
There's been a reproducable USB OHCI/EHCI cpuidle related hang on omap4
for a while that happens after about 20 - 40 minutes on an idle system
with some data feeding device being connected, like a USB GPS device or
a cellular modem.

This issue happens in cpuidle states C2 and C3 and does not happen if
cpuidle is limited to C1 state only. The symptoms are that the whole
system hangs and never wakes up from idle, and if a watchdog is
configured the system reboots after a while.

Turns out that OHCI/EHCI devices on omap4 are trying to use the GIC
interrupt controller directly as a parent instead of the WUGEN. We
need to pass the interrupts through WUGEN to GIC to provide the wakeup
events for the processor.

Let's fix the issue by removing the gic interrupt-parent and use the
default interrupt-parent wakeupgen instead. Note that omap5.dtsi had
this already fixes earlier by commit 7136d457f3 ("ARM: omap: convert
wakeupgen to stacked domains") but we somehow missed omap4 at that
point.

8bafae202c ARM: BUG if jumping to usermode address in kernel mode
Detect if we are returning to usermode via the normal kernel exit paths
but the saved PSR value indicates that we are in kernel mode.  This
could occur due to corrupted stack state, which has been observed with
"ftracetest".

This ensures that we catch the problem case before we get to user code.

Pull timer updates from Thomas Gleixner:

 - The final conversion of timer wheel timers to timer_setup().

   A few manual conversions and a large coccinelle assisted sweep and
   the removal of the old initialization mechanisms and the related
   code.

 - Remove the now unused VSYSCALL update code

 - Fix permissions of /proc/timer_list. I still need to get rid of that
   file completely

 - Rename a misnomed clocksource function and remove a stale declaration

83ada03196 powerpc fixes for 4.15 #2
A small batch of fixes, about 50% tagged for stable and the rest for recently
 merged code.
 
 There's one more fix for the >128T handling on hash. Once a process had
 requested a single mmap above 128T we would then always search above 128T. The
 correct behaviour is to consider the hint address in isolation for each mmap
 request.
 
 Then a couple of fixes for the IMC PMU, a missing EXPORT_SYMBOL in VAS, a fix
 for STRICT_KERNEL_RWX on 32-bit, and a fix to correctly identify P9 DD2.1 but in
 code that is currently not used by default.

Pull SCSI target updates from Nicholas Bellinger:

 "This series is predominantly bug-fixes, with a few small improvements
  that have been outstanding over the last release cycle.

  As usual, the associated bug-fixes have CC' tags for stable.

  Also, things have been particularly quiet wrt new developments the
  last months, with most folks continuing to focus on stability atop 4.x
  stable kernels for their respective production configurations.

  Also at this point, the stable trees have been synced up with
  mainline. This will continue to be a priority, as production users
  tend to run exclusively atop stable kernels, a few releases behind
  mainline.

  The highlights include:

   - Fix PR PREEMPT_AND_ABORT null pointer dereference regression in
     v4.11+ (tangwenji)

   - Fix OOPs during removing TCMU device (Xiubo Li + Zhang Zhuoyu)

   - Add netlink command reply supported option for each device (Kenjiro
     Nakayama)

   - cxgbit: Abort the TCP connection in case of data out timeout (Varun

   - Fix PR/ALUA file path truncation (David Disseldorp)
