In Linux v6.15, the timer APIs hrtimer_init() and del_timer() have been
removed. The hrtimer_setup() was added in Linux v6.13 to replace
hrtimer_init() and hrtimer_init() have finally been removed. The
functions del_timer()/del_timer_sync() were renamed to
timer_delete()/timer_delete_sync() in Linux v6.15. Use conftest to
detect these changes and update the drivers as necessary.

After programming the TX Register, it takes 3-4 clock cycles for TX
data synchronization to the CEC core domain. The TX_EMPTY interrupt
should not be cleared until this data synchronization is complete.
Enable CEC HW feature to automatically clears the TX_EMPTY interrupt
after TX data synchronization is complete. It takes time for HW to
clear the interrupt and TX_EMPTY can still appear high, hence SW
needs to poll WR_LOCK until it goes to 0. This will avoid SW to
attempt the next TX block during the same TX_EMPTY interrupt.
Also read RX_REGISTER based on the buffer occupancy which is
indicated by the CEC_RX_BUFFER_STAT_0 register.

This change adds SC7 wake support to cec driver.
CEC engine can detect TV packets in SC7 state and
can wake up when particular pattern detected.
In resume functionality, the total arrived packets on FIFO
needs to read and reported back to user-space.
This change adds -
1. Program CEC engine to activate for SC7 wake.
2. Program required opcode and physical address.
3. Register for wake and read packets in resume path.
4. Provide sysfs control to program physical address.
Verification of SC7 wake is done for below cases -
1. TV turn on and off is tested.
2. TV source input change is tested.
3. CEC Analyzer set-stream is tested.

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
under respective dc nodes in device tree.

This change fixes below follow-up issues with the earlier fix
to access_ok() API done as part of
https://git-master.nvidia.com/r/c/linux-nvidia/+/2361042:
1. Definition of VERIFY_READ and VERIFY_WRITE have been removed
after K4.14. Hence, used them only for kernel versions < K5.4.
2. Changed access_type parameter of tegra_cec_access_ok() API
to bool. WRITE or READ will be chosen based on the bool value.
3. In the last CL, VERIFY_WRITE was changed to VERIFY_READ in
two access_ok() calls by mistake. Corrected them in this CL.
4. Defined access_type variable with attribute __maybe_unused
since gcc doesn't seem to consider a variable as used if only
passed as function parameter.

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.
