Fix riace condition between host1x_syncpt_alloc()
and host1x_syncpt_put() by using kref_put_mutex()
instead of kref_put() + manual mutex locking.
This ensures no thread can acquire the
syncpt_mutex after the refcount drops to zero
but before syncpt_release acquires it.
This prevents races where syncpoints could
be allocated while still being cleaned up
from a previous release.
Remove explicit mutex locking in syncpt_release
as kref_put_mutex() handles this atomically.

Enhance IOCTL handler to identify and
handle dma_fence_chain objects that might contain
host1x dma fences. This fixes issues
when userspace passes a dma_fence_chain
(created by DRM_IOCTL_SYNCOBJ_TIMELINE_WAIT
operations) to HOST1X_IOCTL_FENCE_EXTRACT.
The updated code iteratively unwraps fence
chains until it finds a host1x_syncpt_fence or
reaches a fence it can't process. This ensures
proper operation with DRM-based applications
that use timeline syncobj features which internally
use dma_fence_chain.

Port the tegra_hv_comm driver to the OOT kernel. This driver allows an
IVC channel to be used as an emulated serial device.
Make the following changes to simplify maintaining compatibility with
different kernel versions:
- Use a generic port type instead of defining a custom one.
- Use existing conftest to determine whether platform_device.remove
returns void.
- Add a conftest to determine whether uart_state.xmit exists.
- Use tty_port.xmit_fifo in kernels where uart_state.xmit has been

When EP boot up first and RP in power OFF state, default PERST# input is
high due to onboard pull up. When RP is powered ON, it causes a glitch
from high to low due to default pinctl settings, it is perceived as
PERST# assert by Endpoint. In tegra264_pcie_ep_rst_assert() PRNST#
signal is released (set high), this will cause PCIe link up failure.
This WAR is initially added for RP reboot case, to handle a scenario
where EP function driver still executing core_deinit as part of PERST#
assert and mean while RP boot up and ready for link up again. However
on Thor it is measured that core_deinit is taking only ~1.4 msec which
completes before RP boots. So, it is safe to remove PRNST# release WAR
in tegra264_pcie_ep_rst_assert(), this fixes link up failure when RP
boot after EP.

Add support to select initial operating mode (GPIO or TIMER)
through DT property "nvpps-event-mode-init".
This allows users to specify which mode the driver should
start in rather than always defaulting to GPIO mode if gpios
property is specified in DT.
Key changes:
- Add DT property parsing for initial event mode
- Add validation to ensure selected mode is supported
- If this property is not specified, default mode selection
happens based on if nvpps-gpios property is defined or not
- Add informative debug messages about selected mode
- Add error handling for invalid configurations(eg: init
mode is GPIO but gpios property is not defined). If
validation fails, probe returns error instead of
defaulting to TIMER mode.
