[ Upstream commit 4641840341f37dc8231e0840ec1514b4061b4322 ]
For example MSM8974 has mx voltage rail exposed as regulator and only cx
voltage rail is exposed as power domain. This power domain (cx) is
attached internally in power domain and cannot be attached in this driver.
Fixes: 8750cf392394 ("remoteproc: qcom_q6v5_mss: Allow replacing regulators with power domains")

[ Upstream commit e917b73234b02aa4966325e7380d2559bf127ba9 ]
Only go into the if condition for single-PD handling when there's
actually just one power domain specified there. Otherwise it'll be an
issue in the dts and we should fail in the regular code path.
This also mirrors the latest changes in the qcom_q6v5_mss driver.

[ Upstream commit efdde3d73ab25cef4ff2d06783b0aad8b093c0e4 ]
There is case as below could trigger kernel dump:
Use U-Boot to start remote processor(rproc) with resource table
published to a fixed address by rproc. After Kernel boots up,
stop the rproc, load a new firmware which doesn't have resource table
,and start rproc.
When starting rproc with a firmware not have resource table,
`memcpy(loaded_table, rproc->cached_table, rproc->table_sz)` will
trigger dump, because rproc->cache_table is set to NULL during the last
stop operation, but rproc->table_sz is still valid.
This issue is found on i.MX8MP and i.MX9.

commit 1dc7c8ed7cb378dd3974387692dfa833aee718d4 upstream.
It's no longer practical for the OMAP IOMMU driver to trick
arm_setup_iommu_dma_ops() into ignoring its presence, so let's use the
same tactic as other IOMMU API users on 32-bit ARM and explicitly kick
the arch code's dma_iommu_mapping out of the way to avoid problems.

commit 7378aeb664e5ebc396950b36a1f2dedf5aabec20 upstream.
In the rproc_alloc() function, on error, put_device(&rproc->dev) is
called, leading to the call of the rproc_type_release() function.
An error can occurs before ida_alloc is called.
In such case in rproc_type_release(), the condition (rproc->index >= 0) is
true as rproc->index has been initialized to 0.
ida_free() is called reporting a warning:

[ Upstream commit dbb9c372555c0b2a5a9264418bfba6d017752808 ]
When multi-core SCP support was added, the driver was made to populate
platform devices for all the sub-nodes. This ended up adding platform
devices for the rpmsg sub-nodes as well, which never actually get used,
since rpmsg devices are registered through the rpmsg interface.
Limit of_platform_populate() to just populating the SCP cores with a
compatible string match list.

Currently, the rproc "atomic_t power" variable is incremented during:
a. WPSS rproc auto boot.
b. AHB power on for ath11k.
During AHB power off (rmmod ath11k_ahb.ko), rproc_shutdown fails
to unload the WPSS firmware because the rproc->power value is '2',
causing the atomic_dec_and_test(&rproc->power) condition to fail.
Consequently, during AHB power on (insmod ath11k_ahb.ko),
QMI_WLANFW_HOST_CAP_REQ_V01 fails due to the host and firmware QMI
states being out of sync.

The remoteproc "name" property is supposed to present the "human

readable, it's not "friendly".
Instead, use the "sysmon_name" as the identifier for the remoteproc

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.
Convert all platform drivers below drivers/remoteproc to use .remove(),
with the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

The k3-m4 remoteproc driver was merged with incorrect dependencies.
Despite multiple people trying to fix this, the version 6.12-rc2
remains broken and causes a build failure with CONFIG_TI_SCI_PROTOCOL=m
when the driver is built-in.
arm-linux-gnueabi-ld: drivers/remoteproc/ti_k3_m4_remoteproc.o: in function `k3_m4_rproc_probe':
ti_k3_m4_remoteproc.c:(.text.k3_m4_rproc_probe+0x76): undefined reference to `devm_ti_sci_get_by_phandle'
Fix the dependency again to make it work in all configurations.
The 'select OMAP2PLUS_MBOX' no longer matches what the other drivers
dependencies. The link failure can be avoided with a simple 'depends
do, so turn that into the same 'depends' to ensure we get no circular
on TI_SCI_PROTOCOL', but the extra COMPILE_TEST alternative is what
we use elsehwere. On the other hand, building for OMAP2PLUS makes
no sense since the hardware only exists on K3.

An of_node_put(rmem_np) call was immediately used after a pointer check
for a of_reserved_mem_lookup() call in three function implementations.
Thus call such a function only once instead directly before the checks.

Selecting CONFIG_OMAP2PLUS_MBOX while compile testing

Using 'select' to force-enable another subsystem is generally
a mistake and causes problems such as this one, so change the
three drivers that link against this driver to use 'depends on'
instead, and ensure the driver itself can be compile tested
regardless of the platform.
When compile-testing without CONFIG_TI_SCI_PROTOCOL=m, there
is a chance for a link failure, so add a careful dependency
on that.

The TI_K3_M4_REMOTEPROC Kconfig entry selects OMAP2PLUS_MBOX, but that
driver in turn depends on other things, which the k4-m4 driver didn't.
This causes a Kconfig time warning:
WARNING: unmet direct dependencies detected for OMAP2PLUS_MBOX
Depends on [n]: MAILBOX [=y] && (ARCH_OMAP2PLUS || ARCH_K3)
Selected by [m]:
- TI_K3_M4_REMOTEPROC [=m] && REMOTEPROC [=y] && (ARCH_K3 || COMPILE_TEST [=y])
because you can't select something that is unavailable.
Make the dependencies for TI_K3_M4_REMOTEPROC match those of the
OMAP2PLUS_MBOX driver that it needs.

By simply bailing out, the driver was violating its rule and internal
assumptions that either both or no rproc should be initialized. E.g.,
this could cause the first core to be available but not the second one,
leading to crashes on its shutdown later on while trying to dereference
that second instance.

On some NXP platforms (e.g i.MX7ULP) the poweroff and reboot operations
are done via a separate remote core.
Typically Linux needs to send a message to the remote core and requests
for poweroff or reboot.
By default the communication between Linux core and the remote core is
is done via a blocking mailbox mechanism but Linux doesn't allow blocking
operations in the system off (reboot, power off) handlers.
So, we need to make sure the mailbox message send operations do not block
for this specific operations. Fortunately, Linux allows us to register
handlers that are called in preparation of the system off operations.
Thus, before carrying the power off or reboot preparations, just destroy
the existing mailboxes and create them as non-blocking.
Note that power off and restart are totally different operations and are
not complementary.
We introduce a new flag in the imx remoteproc per device data which tells
us when a device needs this special setup. For now, only imx7ulp needs it.

Current mailbox is blocking by default, but there are cases where we don't
need to wait for a response.
Linux just needs to send data to the remote processor, so let's
allow tx_block mode to be set (true/false) depending on usecase.
No functional changes.

Few times, core1 was scheduled to boot first before core0, which leads
to error:
'k3_r5_rproc_start: can not start core 1 before core 0'.
This was happening due to some scheduling between prepare and start
callback. The probe function waits for event, which is getting
triggered by prepare callback. To avoid above condition move event
trigger to start instead of prepare callback.

The AM62x and AM64x SoCs of the TI K3 family has a Cortex M4F core in
the MCU domain. This core is typically used for safety applications in a
stand alone mode. However, some application (non safety related) may
want to use the M4F core as a generic remote processor with IPC to the
host processor. The M4F core has internal IRAM and DRAM memories and are
exposed to the system bus for code and data loading.
A remote processor driver is added to support this subsystem, including
being able to load and boot the M4F core. Loading includes to M4F
internal memories and predefined external code/data memories. The
carve outs for external contiguous memory is defined in the M4F device
node and should match with the external memory declarations in the M4F
image binary. The M4F subsystem has two resets. One reset is for the
entire subsystem i.e including the internal memories and the other, a
local reset is only for the M4F processing core. When loading the image,
the driver first releases the subsystem reset, loads the firmware image
and then releases the local reset to let the M4F processing core run.

Acquire the mailbox handle during device probe and do not release handle
