a59a10dfeb drivers: Update timer APIs for Linux v6.15 
In Linux v6.15, the timer APIs hrtimer_init() and del_timer() have been
removed. The hrtimer_setup() was added in Linux v6.13 to replace
hrtimer_init() and hrtimer_init() have finally been removed. The
functions del_timer()/del_timer_sync() were renamed to
timer_delete()/timer_delete_sync() in Linux v6.15. Use conftest to
detect these changes and update the drivers as necessary.

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)

In file: v4l2-subdev.c check_state() function
failed at check:
(!state || !state->pads)
Which caused the function to return -EINVAL=-22.

struct v4l2_subdev contain a member
active_state which should be initialized to
overcome the failure. To fill active_state
call v4l2_subdev_init_finalize in
tegracam_v4l2subdev_register().

This failure is seen in K6.8 because in earlier
kernel, v4l2_subdev_call() was called instead of
v4l2_subdev_call_state_active() in
v4l2_g_parm_cap(). And v4l2_subdev doesn't contain
active_state member in earlier kernel.

6087c01f5d nvidia-oot: camera: isp: track stats syncpt 
This change corrects the logic for tracking stats syncpoint
threshold.

In UMD, IspNg sets flag stats_aidx_flag per stats block enabled.
In RCE, this is copied over to the task descriptor as
stats_action_mask.
In Falcon, this mask is used to determine how many times the
stats syncpoint shall be incremented.

This change fixes the logic in isp_capture_request to have the
threshold be based on the same flag from IspNg, by reading it
from the program buffer.

9cdba26d40 media: camera: Fix build for Linux v6.8+ 
In Linux v6.8, the 'g_frame_interval' and 's_frame_interval' function
pointers were removed from the 'v4l2_subdev_video_ops' structure and
replaced by 'get_frame_interval' and 'set_frame_interval' that were
added to the 'v4l2_subdev_pad_ops' structure.

This change was previously fixed for the Tegra CSI driver by adding the
necessary conftest changes. A new update to the Tegra Cam V4L2 causes
the build to fail for Linux v6.8+ kernels because of the same issue. Fix
up the Tegra Cam V4L2 driver in the same way as the Tegra CSI driver,
but update the name of the conftest test to indicate that this is
applicable for both the 'get_frame_interval' and 'set_frame_interval'
function pointers.
