[ 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.

[ 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.

- The Samsung Exynos family gains a new Chipid driver exporting using
the soc device sysfs interface
- A similar socinfo driver for Qualcomm Snapdragon chips.
- A firmware driver for the NXP i.MX DSP IPC protocol using shared
memory and a mailbox
Other changes:
- The i.MX reset controller driver now supports the NXP i.MX8MM chip
- Amlogic SoC specific drivers gain support for the S905X3 and A311D
chips
- A rework of the TI Davinci framebuffer driver to allow important
cleanups in the platform code
- A couple of device drivers for removed ARM SoC platforms are
removed. Most of the removals were picked up by other maintainers,
this contains whatever was left"

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 ]

TISCI protocol supports for enabling the device either with exclusive
permissions for the requesting host or with sharing across the hosts.
There are certain devices which are exclusive to Linux context and
there are certain devices that are shared across different host contexts.
So add support for getting this information from DT by increasing
the power-domain cells to 2.
For keeping the DT backward compatibility intact, defaulting the
device permissions to set the exclusive flag set. In this case the
power-domain-cells is 1.

i.MX drivers update for 5.4:
- A series from Anson Huang to add UID support for i.MX8 SoC and SCU
drivers.
- A series from Daniel Baluta to add DSP IPC driver for communication
between host AP (Linux) and the firmware running on DSP embedded in
i.MX8 SoCs.
- A small fix for GPCv2 error code printing.
- Switch from module_platform_driver_probe() to module_platform_driver()
for imx-weim driver, as we need the driver to probe again when device
is present later.
- Add optional burst clock mode support for imx-weim driver.

Currently the R-Mobile "always-on" PM Domain is implemented by returning
-EBUSY from the generic_pm_domain.power_off() callback, and doing
nothing in the generic_pm_domain.power_on() callback. However, this
means the PM Domain core code is not aware of the semantics of this
special domain, leading to boot warnings like the following on
SH/R-Mobile SoCs:
sh_cmt e6130000.timer: PM domain c5 will not be powered off
Fix this by making the always-on nature of the domain explicit instead,
by setting the GENPD_FLAG_ALWAYS_ON flag. This removes the need for the
domain to provide power control callbacks.

In commit 40d8aff614f7 ("soc: samsung: chipid: Convert exynos-chipid
driver to use the regmap API") of_find_compatible_node() call was
substituted with syscon_regmap_lookup_by_compatible() but also an error
log was added for case where lookup fails. On multiplatform the lookup
will always fail on any non-samsung device so the log is incorrect.
Remove the error log and just return an error code from
syscon_regmap_lookup_by_compatible() which internally calls
of_find_compatible_node().

The local variable np in function rcar_sysc_pd_init takes the return
value of of_find_matching_node_and_match(), which gets a node but does
not put it. If np is not put before the function returns, it may cause
a memory leak.
Hence, remove the return statement that does not immediately follow a
putting of np. Replace it with a goto pointing to a pre-existing label
that first puts np and then returns the required value.
