Add gpu-static-pg kernel driver to support the
BPMP GPC/TPC/FBP setting via sysfs communication
and module parameter, which allow the nvpmodel
system service to set the mask via the interfaces
above.
For nvpmodel service usecase, this driver should
be probed and the mask should be applied before
the GPU driver is probed.

This driver exposes EMC frequency control interface to user space via
linux devfreq framework.
Users could change EMC frequency to the frequency value from the
available frequencies of EMC clock:
$ /sys/class/devfreq/bwmgr# cat available_frequencies
665600000 2750000000 3200000000 4266000000
and update the EMC floor frequency by writing into the min_freq QoS
sysfs node:
$ /sys/class/devfreq/bwmgr# echo 4266000000 > min_freq
and update the EMC max frequency by writing into the max_rate QoS
sysfs node to cap the EMC frequency:
$ /sys/class/devfreq/bwmgr# echo 4266000000 > max_freq
This driver does not directly manage the EMC clock rate. Instead it
just delivers the min/max frequency information to BPMP, and BPMP is
still the only entity that has the full control of EMC and other
related memory clocks.

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
removed.

Adding dynamic APi dispatch functionality in host1x-fence
modue. This CL exports new host1x wrapper API, which can
be called by client kernel modules. The wrapper API dispatch
call to either Host1x module or Host1x-EMU depending if the
host1x-emu driver registered its interface during its probe.

Use the kernel-source folder name to hide the kernel version path,
and this folder will be created as symlink. Before building kernel,
the script will build the symlink based on the kernel version of
environment variable. The advantage of this is that there is no need
to change the path whenever the version is updated, and the build
can be switched between different kernel version.

1. Add BUILD.bazel file.
2. Add build target of kernel module and required include folder
srctree.* in Makefile to fix the build issue
3. The tr (a build tool defined by kleaf in the sandbox) which
supported by toybox will cause the conversion of header files
to file_define to fail. Fixed it by separating with two tr
commands.
