ef2e125868 drivers:nvpps:optimize TSC align trigger freq 
- use TSC lock trigger interval param from dt to optimize
As per HW suggestion we should not trigger sync on every
PPS edge. TSC needs atleast 2 PPS edges to align with the
PTP clock.

- save platform specific register offset during drv init time
instead of checking plat id everytime in monitoring thread

48e383a1b9 drm/tegra: Add option for explicit syncpoint free 
Add kernel module parameter to enable a mode where syncpoints
must be freed explicitly (using the free IOCTL) or they will be
left dangling. This ensures that, for particularly locked down
configurations, a syncpoint will be forever left in an expected
state even if the process owning it dies -- for example another
process will not be able to allocate it.

9feb2a4347 video: tegra: nvmap: Add multithreaded cache flush support 
On TOT, NvMap does page by page cache flush i.e. it takes virtual
address of each page present in the buffer and then perform cache
flush on it using dcache_by_line_op. This result in very poor
performance for larger buffers. ~70% of the time taken by
NvRmMemHandleAllocAttr is consumed in cache flush.
Address this perf issue using multithreaded cache flush
- Use a threshold value of 32768 pages which is derived from perf
experiments and as per discussion with cuda as per usecases.
- When the cache flush request of >= 32768 pages is made, then vmap
pages to map them in contiguous VA space and create n number of kernel
threads; where n indicate the number of online CPUs.
- Divide the above VA range among the threads and each thread would do
cache flush on the VA range assigned to it.

This logic in resulting into following % improvement for alloc tests.

Buffer Size in MB | % improvement |

7aae5929cb drivers:nvpps:nvpps: support use of higher PPS freq 
- support use of higher PPS freq in nvpps. The freq value
is read from primary mac interface's "nvidia,pps_op_ctrl"
field and vetted for valid values(0,1,2,4,5 & 8).
- To use higher PPS freq, nvpps needs to update K_INT and
REF_FREQ.INC value and also increase the freq of monitoring
thread.

005cbe4462 virt: hvc_sysfs: Another build fix for Linux v6.13 
In Linux v6.13, commit 94a20fb9af16 ("sysfs: treewide: constify
attribute callback of bin_attribute::mmap()") changed the type of
the 'struct bin_attribute' argument of the bin_attribute:mmap function
pointer to const.

One instance of this change has already been fixed in the hvc_sysfs
driver but another case was recently introduced breaking the build for
Linux v6.13. Fix this in the same way as the previous instance.

This reverts commit 40b9876e2f277472677c22b947da7260cf39626e.

Reason for revert:
Initial change to fix year calculation is correct.
We do not need to blindly add +100 in year value. RTC_YEAR
register can accomodate values from 0..199. Being year base 1900
and valid rtc time being 1970, valid year values are 1970..2099.

ee357025ee ufs: Fix Tegra UFS for Linux v6.13 
In Linux v6.13, the quirk definition 'UFSHCD_QUIRK_BROKEN_64BIT_ADDRESS'
was removed and replaced with a function pointer than can be used to set
the DMA mask as needed for a given device. Update the Tegra UFS driver
to fix support for Linux v6.13. Note that prior to Linux v6.13, the flag
'UFSHCD_QUIRK_BROKEN_64BIT_ADDRESS' would set the DMA mask to 32-bits
and so this change is equivalent to the configuration of prior kernels.
