- dce-os-worker.c/.h module exposes functionality which allows
DCE KMD clients to wait/signal events.
- The current abstraction of this module has following drawbacks
which this change attempts to address:
* Name: dce-os-worker is a misnomer
- Rename to dce-wait-cond.c/.h and make it a dce-kmd core file.
- Rename functions accordingly.
* dce-os-worker module initializes data structures from tegra_dce
which makes it ineligible for re-use.
- dce-client-ipc can re-use this module as it uses exact
same functionality.
- But this module is tied with DCE-KMD core such that it has
functions that operate on fixed known inputs.
- dce_os_work_cond_sw_resource_init/deinit()
Inits/Deinits most but not all condition var resources
from tegra_dce. Eg. dce-client-ipc resources
are not initialized.
- Move this function to new core file:dce-waiters.c
- All other functions require msg_id as input and can only
operate on DCE_WAIT* resources making it ineligible
to be used by other clients like dce-client-ipc.
- Refactor these fucntions to operate on
individual wait conditions so that all DCE-KMD
core modules can reuse them.
- Additionally, this change will also remove unused functions
and macros from dce-os-cond.c/.h
- dce-client-ipc will also switch to use dce-wait-cond interface
for client ipc waits.
- Make dce-os-cond.h a common file and move OS specific impl
to dce-os-cond-internal.h

- dce-client-ipc.c has linux specific export symbols that
are required to be exported to linux kernel module client.
- We'll be using dce-client-ipc.c as a core DCE-KMD file and
also be compiling it for HVRTOS.
- This change will add DCE_EXPORT_SYMBOL() as wrapper
to EXPORT_SYMBOL. This will be OS agnostic macro.
- For HVRTOS it will be empty.

- This change will remove linux nuances from dce-client-ipc.c
file and make it a core DCE-KMD file agnostic to OS.
- To do that, dce-client-ipc module will repalce linux specific
nuances for work queue related functionality with
dce-os-work module.
- Further to support existing dce_client_ipc asyn callback function
we need to make worker queue more generic by allowing clients
to pass any data of their choice as data param to the
callback function.
- Also take this opportunity to make following functions static:
- dce_resume_work_fn()
- dce_bootstrap_work_fn()

- This is pre-req to make dce-client-ipc.c a core file and use
it for HVRTOS as well.
- dce-client-ipc.c uses worker queues today to manage async events.
But instead of using existing dce-os-work abstraction it
directly uses linux structs/calls.
- Current dce-os-work abstraction cannot be used as is for
dce-client-ipc.c as it only allows scheduling work
to system hipri work queue. But dce-client-ipc creates
and schedules work to a new worker queue.
- To allow dce-client-ipc.c use exising dce-os-work abstraction,
we need to make it more generic such that work can be scheduled
either to a new queue or existing system hipri work queue.
- This CL will update worker queue abstraction to make it more generic
and start using it for usecases which use default sys hipri WQ.
- There will be a follow-up CL for dce-client-ipc to start using
this abstraction.
- Further, this change will also make WQ and work structs
opaque and make dce-os-work.h a common header.

This change includes below -
1. For T23x, CEC engine is moved to AON partition. As AON partition
does not powergate, skip all powergate/unpowergate calls for t23x.
2. The clock on which CEC engine operates, 32k/rtc_clk, it is always
running clock in AON partition. So skip clock enable/disable APIs.
3. This change also skips calls to TEGRA DC engine which is not available
from T23x.
4. RX Buffer size is increased to 64 depth from 1 depth. So new register is
provided to program depth so that interrupt gets triggered when certain
depth is filled. By default it is 64 depth so program it to 1 depth
to match old behavior.
5. When tegradc is absent, read physical address from SPARE register which
will be populated by UEFI.
6. This change also adds new register definitions in header file which
needs to program when adding support for CEC SC7 wakeup.
7. Timing registers updated for T23x as per HW guidelines.
8. Some initialization code is changed for T23x.
9. Add devicetree binding documentation.

Add genpd/pm_runtime support to handle power domains
in Tegra Display driver. Also updated CEC and HDA_DC
drivers to add pm_runtime calls.
Added new APIs in CEC and SOR drivers to abstract
calls to pm_runtime and tegra_powergate APIs based
on specific Kernel version. Guarded powergate_id
with CONFIG_TEGRA_POWERGATE since its not needed
when pm_runtime APIs are used, and the powergate IDs
are defined in tegra_powergate.h which is not used
in K5.9.
Removed pm_runtime autosuspend setting since display
driver doesn't assign PM suspend/resume hooks at
present. Suspend/resume calls are linked to platform
device callbacks.
Removed pm_runtime_enable() call in dc_common probe
since there's logically no need of power-domains
in dc_common and also there is no power-domains node
in display_hub node in device-tree. Same with DSI.
All the power-domains handled by each DC are listed
in "power-domains" and "power-domain-names" properties

There are two type of temp WARs in the nvidia repo:
1) Some functions are defined in driver files that depend on
CONFIG_TEGRA_GRHOST_NVCSI. So these function call should
have dependency protection in the header file.
2) The powergate header file is adding an unnecessary define
check for tegra194-powergate.h and this broke two places
that were referring one of the defines in it.
So this change fix the WARs above by:
a) Removing those temp WARs by adding dummy NOP functions for
those platofrms that don't have CONFIG_TEGRA_GRHOST_NVCSI.
b) Removing the define check in tegra194-powergate.h and the
version check when referring TEGRA194_POWER_DOMAIN_DISP.
