This reverts commit e9a6d179a42e ("gpu: nvgpu: cache gpu clk rate")
- Real clock rate doesn't always equal clock rate requested by caller
- call of clk_set_rate() and update of cached_rate are not atomic
- Real root cause for Bug 2051688 is in bpmp and gboost design

1) Update header path of gk20a.h files present in os/
to <nvgpu/gk20a.h>
2) os_fence_android_sema.c indirectly was dependent on gk20a.h via
semaphore.h. So, added #include <nvgpu/gk20a.h> in
os_fence_android_sema.c and replaced the header with forward
declaration of struct gk20a in semaphore.h

This patch constructs clk_arbiter specific code for gp10b as well as
gv11b and does the necessary plumbing in the clk_arbiter code. The
changes made are as follows.
1) Constructed clk_arb_gp10b.* files which add support for clk_arb
related HALS including the nvgpu_clk_arb_init and nvgpu_clk_arb_cb.
This doesn't have support for debugfs nor the VFUpdateEvent yet and
consequently no support for arb->notifications.
2) Added gpcclk specific variables corresponding to every gpc2clk in
a given clk_arb related struct.
3) Linux specific support_clk_freq_controller is assigned true in
platform_gp10b.c and platform_gv11b.c files.
4) Incremented the clk_arb_worker.put atomic variable during
worker_deinit so as to allow the worker thread to be stopped.
5) Added the flag clk_arb_events_supported as part of struct
nvgpu_clk_arb. This flag is used to selectively account for the extra
refcounting present in OS specific code i.e.
nvgpu_clk_arb_commit_request_fd. For igpus, the extra refcount is
reduced during nvgpu_clk_arb_release_completion_dev.

Expose the linux specific clock implementations via the HAL
interface to allow nvgpu to use the controls globally. This patch
does the following.
1) Implement a new ops interface and a corresponding linux specific
implementation for allowing nvgpu to iterate through a list of
available clock frequencies via nvgpu_linux_clk_get_f_points().
2) Implement nvgpu_linux_clk_get_range().

- common code will create a list of all counter which make it easier to
iterate all counters.
- Add chip specific file for adding ecc counters.
- add linux specific file os/linux/ecc_sysfs.c to export counters to

This reverts commit 74d786dd1327bafa18b21310ac8d67db4a5614cb.
With the recent powergating changes that got merged in k4.14 and by
disabling CONFIG_PROVE_LOCKING, we no longer see any issues in T186.
The reboots observer earlier have stopped and the status of nvgpu_submit
and nvrm_gpu_tests remain the same without causing any more issues

The last frequency in the local array with all frequencies was missed
as the index was used as count. This caused max frequency to be not
listed among available frequencies, when few frequencies were
configured in BPMPFW-DT.

the logic used for selecting frequencies from achievable frequencies
of the GPU clk is selecting one in a set of 8 frequencies.
This reduces the number of available frequencies when the number of
achievable frequencies is small. Change this implementation to choose
all frequencies when the achievable frequency list is small.

All the powergating features such as railgating and other clock-gating
are disabled temporarily for kernel-4.14 which leads to several kernel-panics.
These will be re-enabled later.

drivers/gpu/nvgpu/common/linux. This changes the meaning of common
