MediaTek bus fabric provides TrustZone security support and data
protection to prevent slaves from being accessed by unexpected
masters.
The security violation is logged and sent to the processor for
further analysis or countermeasures.
Any occurrence of security violation would raise an interrupt, and
it will be handled by mtk-devapc driver. The violation
information is printed in order to find the murderer.

Memory controller drivers for v5.11 - Tegra SoC
There is a bigger work from Dmitry Osipenko around Tegra SoC memory
controller drivers, mostly towards adding interconnect support and
integration with devfreq. This work touches all Tegra memory controller
drivers and also few other SoC-related parts. It's not yet finished but
the intermediate stage seems ready to merge.
Beside that Tegra 210 memory controller got few fixes and received new
swgroups (work of Nicolin Chen).

There does not need to be an of_node_put call in this error handling
block after the shuffling of the np assignment. Remove it so there is
no use of uninitialized memory.

According to Tegra X1 TRM, there are missing swgroups in the
tegra210_swgroups list. So this patch adds them to the list.
Note that the TEGRA_SWGROUP_GPU (in list) should be actually
TEGRA_SWGROUP_GPUB (in TRM), yet TEGRA_SWGROUP_GPU (in TRM) is not being
used -- only TEGRA_SWGROUP_GPUB (in TRM) is. So this patch does not add
TEGRA_SWGROUP_GPU (in TRM) and keeps TEGRA_SWGROUP_GPU (in list)
as it is.

EMC driver will become mandatory after turning it into interconnect
provider because interconnect users, like display controller driver, will
fail to probe using newer device-trees that have interconnect properties.
Thus make EMC driver to probe even if timings are missing in device-tree.

Add missing PTC memory client latency allowness entry to the Tegra MC
drivers.
This prevents erroneous clearing of MC_INTSTATUS 0x0 register during
of the LA programming in tegra_mc_setup_latency_allowance() due to the
missing entry. Note that this patch doesn't fix any known problems.
