a477caa895 video: tegra: nvmap: Disable read/write APIs for prod_nsr 
NvRmMemRead/NvRmMemWrite APIs don't have corresponding requirements in
DriveOS 7.0 Linux NSR. We have taken sign-off from the stakeholders to
confirm that they are not using these APIs in T264 Linux Prod NSR
variant. But some of them are using these APIs in dev_nsr and did not
agree to remove it from dev-nsr, L4T, HOS etc. Hence we need to
make sure that they do not accidentally start using these APIs. Add
bug_on when the corresponding ioctl is called in prod_nsr.

Adding debugfs support for the coordinated wake state.
This will allow for the end-user to select a number of destination CPUs,
and then force them into idle together. A chosen "src" cpu will then
trigger a simultaneous wake request on all of the cores to create the
worst-case idle-exit scenario.
We also have an alternate state to support only coordinated sleep.
This can be useful for cases where select cores coordinated together can
have deeper power modes available to them.

88caf7f818 nvdla: kmd: Move falcon implementation from Host1x to DLA driver 
This commit moves the falcon hardware interface implementation from the
host1x-nvhost driver to the NVDLA kernel driver. This change makes
the DLA driver more independent by removing its dependency on the host1x
driver for falcon functionality.

The falcon hardware interface is critical for DLA firmware loading and
execution. By moving this code into the DLA driver, we improve modularity
and make the driver more self-contained.

Changes include:
- Migrated falcon.c and falcon.h from host1x-nvhost to video/tegra/host/nvdla/flcn/
- Renamed files to nvdla_falcon.c and nvdla_falcon.h
- Added DLA-specific falcon API implementations
- Updated include paths and header guards
- Updated the DLA driver's Makefile to include the new files

794163ce8e media: tegra: Conditionally disable L4T-specific drivers in embedded Linux builds 
This change adds conditional compilation blocks to disable L4T-specific
camera and multimedia drivers when building for embedded Linux platforms.
Key changes include:

- Add ifneq ($(NV_BUILD_SYSTEM_TYPE),embedded-linux) checks in multiple
  Makefiles to exclude L4T-specific components
- Introduce NV_IS_L4T define to conditionally include L4T functionality
- Reorganize header includes to support both L4T and embedded Linux builds
- Conditionally wrap L4T-specific struct members and function calls
- Update module dependencies (cdi_mgr now depends on cdi_dev instead of cdi_pwm)

d8a3d29fed block:vblk: Resolve compile error tegra_vblk V6.11 
Method to configure the struct queue_limits has changed
from kernel v6.11.
The following API's are removed from v6.11
[1] blk_queue_max_secure_erase_sectors
[2] blk_queue_max_discard_sectors
[3] blk_queue_write_cache
[4] blk_queue_logical_block_size
[5] blk_queue_physical_block_size
[6] blk_queue_max_hw_sectors
[7] The semantics of the flag QUEUE_FLAG_NONROT
is set as default value for queues, so this flag
is removed in v6.11.
[8] The flag BLK_MQ_F_SHOULD_MERGE is not valid in
v6.14

The above API's are replaced by direct
assignment to the queue_limits and use the new API
queue_limits_set. This API takes the incoming
values, validates, populates the other members
of the struct accordingly and assigns the
provided queue_limits to the corresponding queue.

The change contains:
 [1] Addition of new approach that is compatible
with v6.11
 [2] Addition of a macro (NV_BLOCK_USE_QUEUE_LIMITS_SET)
for backward compatibility
 [3] This is a special case where both the variable
and the function needs to be present for the macro to be
enabled. The changes were made accordingly.
 [4] The flag BLK_MQ_F_SHOULD_MERGE is protected by
macro
