At the moment, all the Minis running Linux have the same MAC
address (00:10:18:00:00:00), which is a bit annoying.
Expose the PCI node corresponding to the Ethernet device, and
declare a 'local-mac-address' property. The bootloader will update
it (m1n1 already has the required feature). And if it doesn't, then
the default value is already present in the DT.
This relies on forcing the bus number for each port so that the
endpoints connected to them are correctly numbered (and keeps dtc
quiet).

The RPM and RPMh sleep stats are introduced on a number of platforms, to
aid the enablement of entering low power mode.
The MSM8916 support receives some polishing touches, followed by
introduction of the necessary pieces to use the DeviceTree on 32-bit
variants of the MSM8916 platform, in particular to boot the secondary
CPUs. Based on this support for the Samsung Galaxy S4 Mini Value Edition
is introduced.
The Asus Zenfone 2 Laser gained touchscreen, sensors and sdcard support.
MSM8996 got support for the its crypto hardware and the Xiaomi Mi 5
gained a description of its LCD panel.
The Trogdor device on SC7180 gained support for a second source eDP
brigde, while SC7280 gains PCIe support and the newly introduced
Herobrine device.
Both MSM8916 and SDM845 has their standalong SMEM node dropped, in favour
of the newly introduced support for specifying the compatible directly
on the reserved-memory node.
The SM7225 platform is introduced, as a derrivative of SM6350, initial
support for the PM6350 PMIC and based on this the Fairphone 4 is
introduced.
The RB3 and RB5 devices gains msm-id and board-id, to allow the two DTBs
to be baked into a single boot.img that can be booted on both devices.
As the GDSC driver has been extended to properly describe the
relationship between MMCX and MDSS_GDSC, the now deprecated mmcx
regulator is removed from SM8250.
SM8350 gained CPU topology, idle-states and fastrpc support. FastRPC was
also added for SM8150 and the SA8155p ADP got a couple of remoteprocs
enabled.
Additionally a number of DT validation issues was corrected across the
various platforms and devices.

is introduced.
The Asus Zenfone 2 Laser gained touchscreen, sensors and sdcard support.
MSM8996 got support for the its crypto hardware and the Xiaomi Mi 5
gained a description of its LCD panel.
The Trogdor device on SC7180 gained support for a second source eDP
brigde, while SC7280 gains PCIe support and the newly introduced
Herobrine device.
Both MSM8916 and SDM845 has their standalong SMEM node dropped, in favour
of the newly introduced support for specifying the compatible directly
on the reserved-memory node.
The SM7225 platform is introduced, as a derrivative of SM6350, initial
support for the PM6350 PMIC and based on this the Fairphone 4 is
introduced.
The RB3 and RB5 devices gains msm-id and board-id, to allow the two DTBs
to be baked into a single boot.img that can be booted on both devices.
As the GDSC driver has been extended to properly describe the
relationship between MMCX and MDSS_GDSC, the now deprecated mmcx
regulator is removed from SM8250.
SM8350 gained CPU topology, idle-states and fastrpc support. FastRPC was
also added for SM8150 and the SA8155p ADP got a couple of remoteprocs
enabled.
Additionally a number of DT validation issues was corrected across the
various platforms and devices.

The major change here is the disabling of the firmware loades user space
fallback, this is done as arm64 is the only platform with this flag
enabled and as a result doesn't play nice with standard distributions.
It then enables the new limits driver, which controls the hardware based
thermal mitigation on a range of Qualcomm platforms. The prima/pronto
WiFi and Bluetooth drivers are enabled to ensure these features works
out of the box, now that the last details in the dts are landed.
The new driver for acquiring sleep stats is enabled to facilitate the
various efforts on getting these platforms into low power mode.
Lastly the base SC7280 drivers needed to simply boot this platform are
enabled.

Now that entry code handles IRQ entry (including setting the IRQ regs)
before calling irqchip code, irqchip code can safely call
generic_handle_domain_irq(), and there's no functional reason for it to
call handle_domain_irq().
Let's cement this split of responsibility and remove handle_domain_irq()
entirely, updating irqchip drivers to call generic_handle_domain_irq().
For consistency, handle_domain_nmi() is similarly removed and replaced
with a generic_handle_domain_nmi() function which also does not perform
any entry logic.
Previously handle_domain_{irq,nmi}() had a WARN_ON() which would fire
when they were called in an inappropriate context. So that we can
identify similar issues going forward, similar WARN_ON_ONCE() logic is
added to the generic_handle_*() functions, and comments are updated for
clarity and consistency.

In preparation for removing HANDLE_DOMAIN_IRQ_IRQENTRY, have arch/arm64
perform all the irqentry accounting in its entry code.
As arch/arm64 already performs portions of the irqentry logic in
enter_from_kernel_mode() and exit_to_kernel_mode(), including
rcu_irq_{enter,exit}(), the only additional calls that need to be made
are to irq_{enter,exit}_rcu(). Removing the calls to
rcu_irq_{enter,exit}() from handle_domain_irq() ensures that we inform
RCU once per IRQ entry and will correctly identify quiescent periods.
Since we should not call irq_{enter,exit}_rcu() when entering a
pseudo-NMI, el1_interrupt() is reworked to have separate __el1_irq() and
__el1_pnmi() paths for regular IRQ and psuedo-NMI entry, with
irq_{enter,exit}_irq() only called for the former.
In preparation for removing HANDLE_DOMAIN_IRQ, the irq regs are managed
in do_interrupt_handler() for both regular IRQ and pseudo-NMI. This is
currently redundant, but not harmful.
For clarity the preemption logic is moved into __el1_irq(). We should
never preempt within a pseudo-NMI, and arm64_enter_nmi() already
enforces this by incrementing the preempt_count, but it's clearer if we
never invoke the preemption logic when entering a pseudo-NMI.

Going forward we want architecture/entry code to perform all the
necessary work to enter/exit IRQ context, with irqchip code merely
handling the mapping of the interrupt to any handler(s). Among other
reasons, this is necessary to consistently fix some longstanding issues
with the ordering of lockdep/RCU/tracing instrumentation which many
architectures get wrong today in their entry code.
Importantly, rcu_irq_{enter,exit}() must be called precisely once per
IRQ exception, so that rcu_is_cpu_rrupt_from_idle() can correctly
identify when an interrupt was taken from an idle context which must be
explicitly preempted. Currently handle_domain_irq() calls
rcu_irq_{enter,exit}() via irq_{enter,exit}(), but entry code needs to
be able to call rcu_irq_{enter,exit}() earlier for correct ordering
across lockdep/RCU/tracing updates for sequences such as:
lockdep_hardirqs_off(CALLER_ADDR0);
rcu_irq_enter();
trace_hardirqs_off_finish();
To permit each architecture to be converted to the new style in turn,
this patch adds a new CONFIG_HANDLE_DOMAIN_IRQ_IRQENTRY selected by all
current users of HANDLE_DOMAIN_IRQ, which gates the existing behaviour.
When CONFIG_HANDLE_DOMAIN_IRQ_IRQENTRY is not selected,
handle_domain_irq() requires entry code to perform the
irq_{enter,exit}() work, with an explicit check for this matching the
style of handle_domain_nmi().
Subsequent patches will:
1) Add the necessary IRQ entry accounting to each architecture in turn,
dropping CONFIG_HANDLE_DOMAIN_IRQ_IRQENTRY from that architecture's
Kconfig.
2) Remove CONFIG_HANDLE_DOMAIN_IRQ_IRQENTRY once it is no longer
selected.
3) Convert irqchip drivers to consistently use
generic_handle_domain_irq() rather than handle_domain_irq().
4) Remove handle_domain_irq() and CONFIG_HANDLE_DOMAIN_IRQ.
... which should leave us with a clear split of responsiblity across the
entry and irqchip code, making it possible to perform additional
cleanups and fixes for the aforementioned longstanding issues with entry
code.
There should be no functional change as a result of this patch.

For some reason apq8016-sbc, apq8096-db820c, msm8916-mtp and msm8996-mtp
were added as separate .dts and .dtsi files where the first only contains
the model name and the latter contains most of the actual definitions.
Perhaps this was done with the expectation that there would be other
devices also making use of exactly the same. However, this has not
been the case until now and it also seems unlikely in the future.
Having the extra .dtsi only clutters the file list and provides
little benefit.
Move the contents of the .dtsi into the .dts file to make this consistent
with most other devices that simply define everything in the .dts.
There are no functional changes introduced by this patch:

The RTC on the pmk8350 is not useful on all boards. Some boards may
not provide backup power to the PMIC but might have another RTC on the
board that does have backup power. In this case it's better to not use
the RTC on the PMIC.
At the moment, the only boards that includes this PMIC are sc7280-idp
and sc7280-idp2. On sc7280-idp I'm not aware of any other RTCs, but
sc7280-idp2 has a Chrome OS EC on it and this is intended to provide
the RTC for the AP.
Let's do what we normally do for hardware that's not used by all
boards and set it to a default status of "disabled" and then enable it
on the boards that need it.
NOTE: for sc7280-idp it's _possible_ we might also want to add
`allow-set-time;`. That could be the subject of a future patch if it
is indeed true.

as status = "reserved" by default (from the device tree specification):
"Indicates that the device is operational, but should not be used.
Typically this is used for devices that are controlled by another
software component, such as platform firmware."
Since this is part of the MSM8916 SoC it should be added to msm8916.dtsi
but in practice these nodes should only get enabled via an extra include
on ARM32.
This is necessary for some devices with signed firmware which is missing
both ARM64 and PSCI support and can therefore only boot ARM32 kernels.

The LTE version of the S4 Mini VE has a NXP PN547, which is supported
by the nxp-nci-i2c driver in mainline. It seems to detect NFC tags
using "nfctool" just fine, although more testing is difficult given
there seem to be very few useful applications making use of the
Linux NFC subsystem. :(
Note that for some reason Samsung decided to connect the I2C pins
to GPIOs where no hardware I2C bus is available, so we need to
fall back to software bit-banging with i2c-gpio.

Like the Samsung Galaxy A3/A5, the S4 Mini VE uses a Richtek RT5033 PMIC
as battery fuel gauge, charger, flash LED and for some regulators.
For now, only add the fuel gauge/battery device to the device tree,
so we can check the remaining battery percentage.
The other RT5033 drivers need some more work first before
they can be used properly.

The Samsung Galaxy S4 Mini Value Edition is an updated version of the
original S4 Mini based on MSM8916. It is similar to the other Samsung
devices based on MSM8916 with only a few minor differences.
The device tree contains initial support for the S4 Mini Value Edition with:
- UART
- eMMC/SD card (needs quirk for some reason)
- Buttons
- Vibrator
- WiFi/Bluetooth (WCNSS)
- USB
Unfortunately, the S4 Mini VE was released with outdated 32-bit only
firmware and never received any update from Samsung. Since the 32-bit
TrustZone firmware is signed there seems to be no way currently to
actually boot this device tree on arm64 Linux at the moment. :(
However, it is possible to use this device tree by compiling an ARM32 kernel
instead. The device tree can be easily built on ARM32 with an #include
and it works really well there. To avoid confusion for others it is still
better to add this device tree on arm64. Otherwise it's easy to forget
to update this one when making some changes that affect all MSM8916 devices.
Maybe someone finds a way to boot ARM64 Linux on this device at some point.
In this case I expect that this device tree can be simply used as-is.

Since the kretprobe replaces the function return address with
the kretprobe_trampoline on the stack, stack unwinder shows it
instead of the correct return address.
This checks whether the next return address is the
__kretprobe_trampoline(), and if so, try to find the correct
return address from the kretprobe instance list. For this purpose
this adds 'kr_cur' loop cursor to memorize the current kretprobe
instance.
With this fix, now arm64 can enable
CONFIG_ARCH_CORRECT_STACKTRACE_ON_KRETPROBE, and pass the
kprobe self tests.

Make a frame pointer (make the x29 register points the
address of pt_regs->regs[29]) on __kretprobe_trampoline.
This frame pointer will be used by the stacktracer when it is
called from the kretprobe handlers. In this case, the stack
tracer will unwind stack to trampoline_probe_handler() and
find the next frame pointer in the stack frame of the
__kretprobe_trampoline().

Record the frame pointer instead of stack address with kretprobe
instance as the identifier on the instance list.
Since arm64 always enable CONFIG_FRAME_POINTER, we can use the
actual frame pointer (x29).
This will allow the stacktrace code to find the original return
address from the FP alone.

Arm Neoverse-N2 and Cortex-A710 cores are affected by an erratum where
the trbe, under some circumstances, might write upto 64bytes to an
address after the Limit as programmed by the TRBLIMITR_EL1.LIMIT.
This might -
- Corrupt a page in the ring buffer, which may corrupt trace from a
previous session, consumed by userspace.
- Hit the guard page at the end of the vmalloc area and raise a fault.
To keep the handling simpler, we always leave the last page from the
range, which TRBE is allowed to write. This can be achieved by ensuring
that we always have more than a PAGE worth space in the range, while
calculating the LIMIT for TRBE. And then the LIMIT pointer can be
adjusted to leave the PAGE (TRBLIMITR.LIMIT -= PAGE_SIZE), out of the
TRBE range while enabling it. This makes sure that the TRBE will only
write to an area within its allowed limit (i.e, [head-head+size]) and
we do not have to handle address faults within the driver.

Arm Neoverse-N2 (#2067961) and Cortex-A710 (#2054223) suffers
from errata, where a TSB (trace synchronization barrier)
fails to flush the trace data completely, when executed from
a trace prohibited region. In Linux we always execute it
after we have moved the PE to trace prohibited region. So,
we can apply the workaround every time a TSB is executed.
The work around is to issue two TSB consecutively.
NOTE: This errata is defined as LOCAL_CPU_ERRATUM, implying
that a late CPU could be blocked from booting if it is the
first CPU that requires the workaround. This is because we
do not allow setting a cpu_hwcaps after the SMP boot. The
other alternative is to use "this_cpu_has_cap()" instead
of the faster system wide check, which may be a bit of an
overhead, given we may have to do this in nvhe KVM host
before a guest entry.

Arm Neoverse-N2 and the Cortex-A710 cores are affected
by a CPU erratum where the TRBE will overwrite the trace buffer
in FILL mode. The TRBE doesn't stop (as expected in FILL mode)
when it reaches the limit and wraps to the base to continue
writing upto 3 cache lines. This will overwrite any trace that
was written previously.
Add the Neoverse-N2 erratum(#2139208) and Cortex-A710 erratum
(#2119858) to the detection logic.
This will be used by the TRBE driver in later patches to work
around the issue. The detection has been kept with the core
arm64 errata framework list to make sure :
- We don't duplicate the framework in TRBE driver
- The errata detection is advertised like the rest
of the CPU errata.
Note that the Kconfig entries are not fully active until the
TRBE driver implements the work around.
