commit d0384eedcde21276ac51f57c641f875605024b32 upstream.
The firmware driver is optional, but the power driver depends on it,
which needs to be reflected in Kconfig to avoid link errors:
aarch64-linux-ld: drivers/soc/xilinx/zynqmp_power.o: in function `zynqmp_pm_isr':
zynqmp_power.c:(.text+0x284): undefined reference to `zynqmp_pm_invoke_fn'
The firmware driver can probably be allowed for compile-testing as
well, so it's best to drop the dependency on the ZYNQ platform
here and allow building as long as the firmware code is built-in.

[ Upstream commit e0ea2d11f8a08ba7066ff897e16c5217215d1e68 ]
Currently we wait only until the PGC inverts the isolation setting
before disabling the peripheral clocks. This doesn't ensure that the
reset is properly propagated through the peripheral devices in the
power domain.
Wait until the PGC signals that the power up request is done and
wait a bit for resets to propagate before disabling the clocks.

[ Upstream commit fe8fe7723a3a824790bda681b40efd767e2251a7 ]
The dpio irqs must be registered when you can actually
receive interrupts, ie when the dpios are created.
Kernel goes through NULL pointer dereference errors
followed by kernel panic [1] because the dpio irqs are
enabled before the dpio is created.

commit a9e9028b4a282f3676450a9c729b8b899a16c414 from
git@git.assembla.com:cavium/WindRiver.linux.git
Use SMC OCTEONTX_EDAC to inject ECC errors to DRAM & cache.
This provides an SMC error injection interface, for verifying
OcteonTX2's RAS/EDAC handling.
For example, injecting DRAM ECC single-bit error
at 8MB, and reading it back in EL3 ...
# edac=/sys/module/otx2_einj/parameters/smc_params
# echo 3,0x800000,0x300 >$edac
will cause ATF to inject error, field EL3 interrupt reporting it,
log that in the sdei-ghes area monitored by otx2-ghes driver,
which passes details to generic edac_ghes driver, which logs
the following via syslog (which may display in /var/log/kern.log,
or elsewhere, depending on syslog configuration)
{1}[Hardware Error]: Hardware error from APEI \

commit 128bdf7581fb9f7d92e8714ed679363d3ad06953 from
git@git.assembla.com:cavium/WindRiver.linux.git
This patch introduce PRBS command to serdes debugfs by adding
octeontx2_serdes/prbs file. It allows to start and stop PRBS on
specified QLM. When PRBS is running, errors for each QLM lane can be
collected.
debugfs/octeontx2_serdes# echo 2 start 7 > prbs
Above command will start PRBS-7 on QLM2.
debugfs/octeontx2_serdes# cat > prbs
This command output will look like this:
Time: 10 seconds QLM2.Lane0: errors: 3
Time: 10 seconds QLM2.Lane1: errors: 0
Time: 10 seconds QLM2.Lane2: errors: 2
Time: 10 seconds QLM2.Lane3: errors: 3
If PRBS is started on multiple QLMs, the QLM from which output will be
printed is selected by running:
debugfs/octeontx2_serdes# echo <qlm> > prbs
To stop PRBS on QLM2 following command is used:
debugfs/octeontx2_serdes# echo 2 stop > prbs

commit 2aa5339be19a3d2906a348e571a62d06805360b0 from
git@git.assembla.com:cavium/WindRiver.linux.git
Enable the firmware (ATF) to report RAS errors
from the LMC, MCC or MDC.
The Generic Hardware Error Source (GHES) allows for
non-standard errors to be reported to the system
(please refer to the ACPI specification).
The standard GHES driver requires the presence of
ACPI tables, and accompanying kernel ACPI support.
However, OcteonTX2 is commonly used in embedded
context with Device Tree, which disables ACPI
in the kernel. Therefore, the standard GHES
driver does not load or function.
Add support for GHES through a platform driver,
using data from the Device Tree to construct the
required ACPI table (Hardware Error Source Table,
or HEST) and inform the kernel thereof.
Additionally, create GHES devices for the LMC,
MCC & MDC OcteonTX2 devices, allowing the firmware
to propagate detected RAS errors to the kernel.

Reading this file will print a compined enable status for all cores.
Value read will be 1 if counter is enabled on all cores.
Access is enabled with as little PMU register modifications as possible.

commit 25da778fa5fe3825841a9e1ac6649ced2bcb85c0 from
git@git.assembla.com:cavium/WindRiver.linux.git
This patch adds a driver for managing non-NIC hardware offload resources
and exposing them to user through SSO/TIM type of RVU VF devices.
For that reason it acts as a proxy for RVU MBOX messages between SSO/TIM
RVU VFs and RVU AF.
It has previously lived outside of the Marvell internal kernel tree
which is not convenient in development process. Therefore this patch
aims to integrate this driver here with a caveat that upstreaming
process will have to include its re-work.
This driver contains a copy of quota management that is part of RVU AF
driver. That code is not re-used as it would require re-work of the
RVU AF driver which is in process of upstreaming. As part of upstreaming
the resource management interfaces used in this driver will have to
be re-worked too (suggested by upstream maintainers to use devlink) to
accommodate requirements of other users to minimize the functionality of
this driver to an RVU stub.

[ Upstream commit 03729cfa0d543bc996bf959e762ec999afc8f3d2 ]
Any user of wkup_m3_ipc calls wkup_m3_ipc_get to get a handle and this
checks the value of the static variable m3_ipc_state to see if the
wkup_m3 is ready. Currently this is populated during probe before
rproc_boot has been called, meaning there is a window of time that
wkup_m3_ipc_get can return a valid handle but the wkup_m3 itself is not
ready, leading to invalid IPC calls to the wkup_m3 and system
instability.
To avoid this, move the population of the m3_ipc_state variable until
after rproc_boot has succeeded to guarantee a valid and usable handle
is always returned.

commit a4e55ccd4392e70f296d12e81b93c6ca96ee21d5 upstream.
snoop_file_poll() is defined as returning 'unsigned int' but the
.poll method is declared as returning '__poll_t', a bitwise type.
Fix this by using the proper return type and using the EPOLL
constants instead of the POLL ones, as required for __poll_t.

commit 4194b583c104922c6141d6610bfbce26847959df upstream.
If the DTB for a device with an RZ/A2 SoC lacks a device node for the
BSID register, the ID validation code falls back to using a register at
address 0x0, which leads to undefined behavior (e.g. reading back a
random value).
This could be fixed by letting fam_rza2.reg point to the actual BSID
register. However, the hardcoded fallbacks were meant for backwards
compatibility with old DTBs only, not for new SoCs. Hence fix this by
validating renesas_family.reg before using it.

commit c9e753767a9c75d2044fb7343950a6a992d34a16 upstream.
Interrupts that don't have an associated wake event or GPIO wake events
end up with an associate IRQ chip that is NULL and which causes IRQ code
to crash. This is because we don't implicitly set the parent IRQ chip by
allocating the interrupt at the parent. However, there really isn't a
corresponding interrupt at the parent, so we need to work around this by
setting the special no_irq_chip as the IRQ chip for these interrupts.

Pull ARM SoC platform updates from Arnd Bergmann:
"The main change this time around is a cleanup of some of the oldest
platforms based on the XScale and ARM9 CPU cores, which are between 10
and 20 years old.
The Kendin/Micrel/Microchip KS8695, Winbond/Nuvoton W90x900 and Intel
IOP33x/IOP13xx platforms are removed after we determined that nobody
is using them any more.
The TI Davinci and NXP LPC32xx platforms on the other hand are still
in active use and are converted to the ARCH_MULTIPLATFORM build,
meaning that we can compile a kernel that works on these along with
most other ARMv5 platforms. Changes toward that goal are also merged
for IOP32x, but additional work is needed to complete this. Patches
for the remaining ARMv5 platforms have started but need more work and
some testing.
Support for the new ASpeed AST2600 gets added, this is based on the
Cortex-A7 ARMv7 core, and is a newer version of the existing ARMv5 and
ARMv6 chips in the same family.
Other changes include a cleanup of the ST-Ericsson ux500 platform and
the move of the TI Davinci platform to a new clocksource driver"
[ The changes had marked INTEL_IOP_ADMA and USB_LPC32XX as being
buildable on other platforms through COMPILE_TEST, but that causes new
warnings that I most definitely do not want to see during the merge
window as that could hide other issues.
So the COMPILE_TEST option got disabled for them again - Linus ]
