1. Add mechanism(s) to trigger syncpoint fence scan when
syncpoint increment UMD called. Following methods are added.
- METHOD-1: Check fence expire in user context when syncpoint
increment UMD API is called.
- METHOD-2: Add tasklet based mechanism that schedule tasklet to scan for
syncpoint fence expiry. This also improve signaling latency.
METHOD-1 is enabled by default, to enable METHOD-2 define MACRO
"HOST1X_EMU_SYNC_INC_TASKLET".
2. Add interface "host1x_syncpt_fence_scan()" that can be called from
client interrupt handler to initiate syncpoint fence scan.

Fix v4l2-compliance VIDIOC_G/S_PARM failure.
Below is the function call sequence starting from
ioctl.
doioctl(VIDIOC_G_PARM)
vidioc_g_parm
tegra_channel_g_parm
v4l2_g_parm_cap
v4l2_subdev_call_state_active
v4l2_subdev_call
v4l2_subdev_call_wrappers.pad.get_frame_interval
call_get_frame_interval
check_frame_interval
check_state
In file: v4l2-subdev.c check_state() function
failed at check:
(!state || !state->pads)
Which caused the function to return -EINVAL=-22.
struct v4l2_subdev contain a member
active_state which should be initialized to
overcome the failure. To fill active_state
call v4l2_subdev_init_finalize in
tegracam_v4l2subdev_register().
This failure is seen in K6.8 because in earlier
kernel, v4l2_subdev_call() was called instead of
v4l2_subdev_call_state_active() in
v4l2_g_parm_cap(). And v4l2_subdev doesn't contain
active_state member in earlier kernel.

Sparse defect stated that "iovmm_debugfs_info" was not declared. Should it be static?
and symbol 'nvmap_max_handle_count' was not declared. Should it be static?
-Since iovmm_debugfs_info is only used in nvmap_debug.c, hence it can be

- 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

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.

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

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.
