- 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

- 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.

- Move resource init specific to PM and bootstrap modules
to respective PM and bootstrap init functions.
- Motivation here is 2 fold:
1) To keep common code common across OSs.
2) Move resource init to respective sub-modules.
- We will have separate PM module for HVRTOS.
- We will have separate dce-worker module for HVRTOS.

Once we complete EVENT_ID_DCE_BOOT_COMPLETE_RECEIVED event handling, it
doesn't reset the complition variable. Which causes
dce_wait_interruptible to exit early without waiting in next cycle.
This patch fixes the same by resetting complition variable after use for
EVENT_ID_DCE_BOOT_COMPLETE_RECEIVED.

For T23x, we have a separate R5 based cluster
named as Display Controller Engine(DCE) to run
our Display RM code. This driver will run on CPU
with the following functionality:
Via debugfs for test and bring-up purposes:
1. Reads the DCE firmware image into DRAM.
2. Sets up DCE AST to cover the DCE firmware image.
3. Sets up R5 reset vector to point to DCE firmware
entry point
4. Brings DCE out of reset
5. Dumps various regsiters for debug
In production env:
1. Manages interrupts to CPU from DCE
2. Uses bootstrap command interface to define Admin
IPC
3. Locks down bootstrap command interface
4. Uses Admin IPC to define message IPC
5. Uses Admin IPC to define message IPC payload area
6. Uses Admin IPC to set IPC channels
6. Uses Admin IPC to define crashdump area
(optional)
7. Provides IPC interfaces for any DCE Client running
on CCPLEX including Display RM.
8. Uses Admin IPC to set logging level (optional)
This patch puts a framework in place with the
following features :
1. Firmware Loading
2. AST Configuration
3. DCE Reset with EVP Programming
4. Logging Infra
5. Debugfs Support
6. Interrupt Handling
7. Mailbox Programming
8. IPC Programming
