The compiler option -Wmissing-prototypes is being enabled globally in
the upstream Linux kernel and this causes build failures for various
drivers. The build failures occur because either the driver is missing
an include file which has the prototype or because the function is not
declared statically when it should be (ie. there are no external users).
Fix the various build failures and enable -Wmissing-prototypes to
prevent any new instances from occurring. Note that the only driver that
is not fixed at the moment is rtl8822ce due to large number of failures
and so build this with '-Wno-missing-prototypes' for now, which is not
different to how it was being compiled prior to this change.

Fix issue in building the DTBs when KERNEL_OUTPUT and KERNEL_HEADERS
are specified as different directories in the OOT modules' Makefile.
In that case, srctree is set to KERNEL_HEADERS and objtree is set to
KERNEL_OUTPUT, and device-tree Makefile should be able to handle the
case when srctree and objtree are specified as different directories.

The Tegra124 SPI slave driver declares a prototype for the function
tegra_spi_slave_register_callback() that does not exist. The correct
function name is tegra124_spi_slave_register_callback() and so fix the
prototype accordingly. Move the prototype to an actual header because
this is the correct place for defining prototypes for other drivers to
reference. This was caught by enabling the compiler flag
-Wmissing-prototype.

Instead of using kernel version checks in the Tegra DRM driver for the
tegra_fb_ops structure, just check if the appropriate definition is
defined and if so use it. This fixes building the Tegra DRM driver
against some 3rd party kernels that include backports from upstream.
Note that this also aligns the driver closer to the upstream code by
using the same definitions that the upstream driver uses.

The Nvhost-related APIs have been deprecated and are no longer
supported since our migration from K510 to K515. Therefore, the camera
platform driver should refrain from using "nvhost_*" functions to set
the clock rate.
Integrate the common operation callback interface into the
tegra_camera_dev_info structure. This modification allows individual
drivers to achieve clock set rate operations by registering the
callback and completing the implementation.

This change adds a cooling device driver to notify the user space of the
thermal trip event. To avoid having user space process poll the
cooling state, a sysfs node is exposed that supports blocking reads.
The driver also supports a timeout (in milliseconds) for blocking reads
which can be done by writing the value to thermal_trip_event_block node
before reading. The blocked user space process will be woken up when the
cooling device becomes active or times out.

When BPMP BWMGR receives ICC avg_bw requests from different memory
clients, it will sum up all avg_bw values together and use it to
determine the final EMC frequency.
Transitioning to ICC peak_bw requests will cause BPMP to evaluate
the bandwidth requirements of each memory client individually,
selecting the maximum bandwidth request from among all the clients
to determine the final EMC frequency.
This modification prevents excessive memory bandwidth allocation
when multiple host1x clients collaborate for data processing.
Currently, host1x clients request the full theoretical 100% data
bandwidth, even though the system typically doesn't fully utilize
that amount during runtime.
To address the issue of insufficient memory bandwidth when multiple
host1x clients are used together, we can reduce the boost_up_threshold
value of cactmon DFS. This adjustment ensures that when actual memory
bandwidth utilization surpasses the specified boost-up bandwidth
threshold, EMC frequency will be further scaled by one step further
to alleviate the problem.
