Regulators, which are marked as 'on-in-suspend' seems to be critical for
board operation, thus they must not be disabled anytime. This can be
only assured by marking them as 'always-on', because otherwise some
actions of their clients might result in turning them off. This patch
restores suspend/resume operation on Peach-Pit Chromebook board. It
partially reverts 'always-on' property removal done by the commit
mentioned in the Fixes tag.

Some architectures need to use stop_machine() to patch functions for
ftrace, and the assumption is that the stopped CPUs do not make function
calls to traceable functions when they are in the stopped state.
Commit ce4f06dcbb ("stop_machine: Touch_nmi_watchdog() after
MULTI_STOP_PREPARE") added calls to the watchdog touch functions from
the stopped CPUs and those functions lack notrace annotations. This
leads to crashes when enabling/disabling ftrace on ARM kernels built
with the Thumb-2 instruction set.
Fix it by adding the necessary notrace annotations.

Reset the KASAN shadow state of the task stack before rewinding RSP.
Without this, a kernel oops will leave parts of the stack poisoned, and
code running under do_exit() can trip over such poisoned regions and cause
nonsensical false-positive KASAN reports about stack-out-of-bounds bugs.
This does not wipe the exception stacks; if an oops happens on an exception
stack, it might result in random KASAN false-positives from other tasks
afterwards. This is probably relatively uninteresting, since if the kernel
oopses on an exception stack, there are most likely bigger things to worry
about. It'd be more interesting if vmapped stacks and KASAN were
compatible, since then handle_stack_overflow() would oops from exception
stack context.

The newly added code that emits ksymtab entries as pairs of 32-bit
relative references interacts poorly with the way powerpc lays out its
address space: when a module exports a per-CPU variable, the primary
module region covering the ksymtab entry -and thus the 32-bit relative
reference- is too far away from the actual per-CPU variable's base
address (to which the per-CPU offsets are applied to obtain the
respective address of each CPU's copy), resulting in corruption when the
module loader attempts to resolve symbol references of modules that are
loaded on top and link to the exported per-CPU symbol.
So let's disable this feature on powerpc. Even though it implements
CONFIG_RELOCATABLE, it does not implement CONFIG_RANDOMIZE_BASE and so
KASLR kernels (which are the main target of the feature) do not exist on
powerpc anyway.

100 ms is not enough time for the LSPCON adapter on Intel NUC devices to
settle. This causes dropped display modes at boot or screen reconfiguration.
Empirical testing can reproduce the error up to a timeout of 190 ms. Basic
boot and stress testing at 200 ms has not (yet) failed.
Increase timeout to 400 ms to get some margin of error.
Changes from v1:
The initial suggestion of 1000 ms was lowered due to concerns about delaying
valid timeout cases.

This patch adds missing properties to the CODEC and sound nodes, so the
audio will work also on Snow rev5 Chromebook. This patch is an extension
to the commit e9eefc3f8c ("ARM: dts: exynos: Add missing clock and
DAI properties to the max98095 node in Snow Chromebook")
and commit 6ab569936d ("ARM: dts: exynos: Enable HDMI audio on Snow
Chromebook"). It has been reported that such changes work fine on the
rev5 board too.

The LDO28 is used only on Odroid XU3 for Display Port. Define it so DTS
will describe entire hardware.
Depending on bootloader behavior this might affect the Display Port
because none of drivers are enabling it. By default it is off in S2MPS11
PMIC reset values. However it could be enabled by bootloader so in such
case kernel will later disable it as unused regulator.

Disable unused PMIC regulators on Exynos5422 Odroid boards to reduce
energy used. According to schematics:
1. LDO12, LDO16 and LDO24 are not connected,
2. LDO26 is not used on Odroid HC1.

1 GHz CPU OPP is the default boot value for the Exynos5250 SOC, so mark it
as suspend OPP. This fixes suspend/resume on Samsung Exynos5250 Snow
Chomebook, which was broken since switching to generic cpufreq-dt driver
in v4.3.

Convert Exynos5250 to OPP-v2 bindings. This is a preparation to add proper
support for suspend operation point, which cannot be marked in opp-v1.

- i.MX display folks decided to switch MXS display driver from legacy
FB to DRM during 4.19 merge window. It leads to a fallout on some
Freescale/NXP development boards with Seiko 43WVF1G panel, because
this DRM panel driver is not enabled in i.MX defconfig. Here is
a series from Fabio to convert i.MX23/28 EVK DT to Seiko 43WVF1G
panel bindings and enable the panel driver in i.MX defconfig, so that
users can still get functional LCD on these boards by default.
- A fix from Leonard to revert incorrect legacy PCI irq mapping in
i.MX7 device tree, that was caused by document errors.
