Ketan Patil 3bea329573 NVIDIA: SAUCE: memory: tegra: Disable mc-err handling in upstream
In t264, the mc-err handling flow is pretty different than t234 and
older chips. The new flow has been added in downstream mc-err driver for
t264. Hence it is needed to use downstream irq handler code for t264 mc-
err. Do not specify irq handler for t264 in upstream mc driver, so that
it can use the downstream mc-err handling code.
Later on, we need to move downstream mc-err code into upstream mc
driver and upstream it.

Joe Hattori 0832002a03 memory: tegra20-emc: fix an OF node reference bug in tegra_emc_find_node_by_ram_code()
BugLink: https://bugs.launchpad.net/bugs/2111953

[ Upstream commit b9784e5cde1f9fb83661a70e580e381ae1264d12 ]

As of_find_node_by_name() release the reference of the argument device
node, tegra_emc_find_node_by_ram_code() releases some device nodes while
still in use, resulting in possible UAFs. According to the bindings and
the in-tree DTS files, the "emc-tables" node is always device's child
node with the property "nvidia,use-ram-code", and the "lpddr2" node is a
child of the "emc-tables" node. Thus utilize the
for_each_child_of_node() macro and of_get_child_by_name() instead of
of_find_node_by_name() to simplify the code.

This bug was found by an experimental verification tool that I am
developing.

Jon Hunter b420189e8f memory: tegra: Correct DLA client names
BugLink: https://bugs.launchpad.net/bugs/2060097

[ Upstream commit 51d915cbeef4c7a154f5d810b1e10d8125f2b0cc ]

Some of the names for the Tegra234 DLA clients are not unique and do not
align with the name of the client ID definitions. Therefore, it is not
possible to determine the exact DLA client from messages that print the
client name. Fix this by correcting the DLA memory client names for
Tegra234 to align with the name of the corresponding memory client ID.

Note that although the client names are also used by the interconnect
framework, interconnect support for the DLA clients has not been added
and so this issue does not impact the interconnect support.

Uwe Kleine-König 622fa819a2 memory: tegra210-emc: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Jason Gunthorpe c462944901 iommu/tegra-gart: Remove tegra-gart
Thierry says this is not used anymore, and doesn't think it makes sense as
an iommu driver. The HW it supports is about 10 years old now and newer HW
uses different IOMMU drivers.

As this is the only driver with a GART approach, and it doesn't really
meet the driver expectations from the IOMMU core, let's just remove it
so we don't have to think about how to make it fit in.

It has a number of identified problems:
 - The assignment of iommu_groups doesn't match the HW behavior

 - It claims to have an UNMANAGED domain but it is really an IDENTITY
   domain with a translation aperture. This is inconsistent with the core
   expectation for security sensitive operations

 - It doesn't implement a SW page table under struct iommu_domain so
   * It can't accept a map until the domain is attached
   * It forgets about all maps after the domain is detached
   * It doesn't clear the HW of maps once the domain is detached
     (made worse by having the wrong groups)

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

initialize even when this MRQ is not supported in any platform.
The check ensures that the MRQ is called only when it is supported

With the introduction of commit 9365bf006f ("PCI: tegra194: Add
interconnect support in Tegra234"), the PCI driver on Tegra194 and later
requires an interconnect provider. However, a provider is currently only
exposed on Tegra234 and this causes PCI on Tegra194 to defer probe
indefinitely.

Fix this by adding a dummy implementation on Tegra194. This allows nodes
to be provided to interconnect consumers, but doesn't do any bandwidth
accounting or frequency scaling.

Ashish Mhetre ef86b2c280 memory: tegra: Remove clients SID override programming
On newer Tegra releases, early boot SID override programming and SID
override programming during resume is handled by bootloader.
In the function tegra186_mc_program_sid() which is getting removed, SID
override register of all clients is written without checking if secure
firmware has allowed write on it or not. If write is disabled by secure
firmware then it can lead to errors coming from secure firmware and hang
in kernel boot.
Also, SID override is programmed on-demand during probe_finalize() call
of IOMMU which is done in tegra186_mc_client_sid_override() in this same
file. This function does it correctly by checking if write is permitted
on SID override register. It also checks if SID override register is
already written with correct value and skips re-writing it in that case.

Mikko Perttunen 7946920d40 memory: tegra: Add API for retrieving carveout bounds
On Tegra234 NVDEC firmware is loaded from a secure carveout, where it
has been loaded by a bootloader. When booting NVDEC, we need to tell it
the address of this firmware, which we can determine by checking the
starting address of the carveout. As such, add an MC API to query the
bounds of carveouts, and add related information on Tegra234.
