Update from error injection framework to event injection framework to
support PF event inducement and node event. Different set of user
input parameters are required dependent on which event to injection.
ICP and ISP support error event and page fault event injection. JPEG
supports node event and page fault event injection. However, buf done
error injection is only supported for JPEG and ICP.
Create a query API to check whether PF is fatal for a context bank.
Using the API, if PF is fatal, page fault event injection is not
supported for the device that owns the context bank.
Make change to JPEG context event callback handling to account for
various events including Event Injection event.

Shared memory is initialized by CRM and used by
other drivers; with CRM not active other drivers
would fail to access the shared memory if
memory manager is deinit. Reader Writer locks can
prevent the open/close/ioctl calls from other drivers
if CRM open/close is already being processed.
Issue observed with the below sequence if drivers
are opened from UMD directly without this change.
CRM Open successful,ICP open successful,
CRM close in progress, ICP open successful,
mem mgr deinit and CRM close successful,
ICP tries to access HFI memory and result in crash.
This change helps to serialze the calls and prevents
issue.

Upon Page Fault, smmu driver invokes faulted client's callback
which looks for faulted buffer and context. The client driver
can be ISP, ICP, JPEG, IFE CDM and CPAS CDM. The driver then
fills PF msg struct, logs related info, and notify PF msg to
userspace. Userspace is expected to abort and calls to shut
down kernel drivers. When Titan powers on next session, CAMSS
undergoes async reset.
This change also ensures the page fault related changes added
to TFE, OPE, CRE do not break the drivers compilation.

Based on targets, in case of device crash, in place
of complete memory dump, mini dump can be extracted.
This commit adds changes in context utils for NRT devices
and in ICP, JPEG drivers.

In subdev close call if CRM is still active wait for shutdown
from CRM [media device]. Remove subdevice check for active
handles, shutdown to happen irrespective of any active context.
If CRM is not active, subdevice shutdown should ensure there is
no access to kernel allocated buffers since at this point
memmgr is de-initialized.
As part of ICP close, remove usage of HFI queues, trigger PIL
to transfer FW memory ownership back to HLOS and power off ICP.

when provider crash occurred, there was a CSID lane overflow
observed due to shutdown sequence from CRM(sensor, csid, csiphy).
To fix the issue need to change the shutdown sequence
(csid, sensor, csiphy).
This change will update the devices sequence in order while registering
and close the sequence accordingly.

Currently when page fault happen, iommu driver callers camera
handler with CB details and iova address which caused the page
fault. With iommu iova address cam smmu driver finds the
closest mapping address for that cb and call the
corresponding driver to find the which port caused page fault.
This has limitation has page fault address always not mapped.
New approach is get the page fault ids from iommu driver.
Based on the Pid and Mid values, get the HW id and port ids,
go through all context which has this hw id and port id and log
the data. Once context id is identified, log the acquire data and
last consumed client address details. Dump the hw register data
in the given buffer. Send the smmu page fault event through
v4l2 queue to user.

Due to the asynchronous nature of platform probes, inter
dependency between drivers needs to be taken care during
kernel boot up. Component helper provides the facility of
adding matching drivers in a list ordered in the way we want
to bind those drivers. The CRM driver acts as component master
to make sure all slave drivers are bound before it returns
from its own bind call. Add support for serializing platform
probes through component framework.

Currently camera modules platform registration/remove function
is being called as a part of module_init function individually.
Building camera as module, current infrastructure cannot support
it, as DLKM only support single module_init/exit function.
This change enables that support by combining all platform
entry/remove functions centrally. Also, remove all submodule
makefiles and combined into one root makefile in order to generate
single kernel object file to dynamically loading the kernel module
in case of DLKM compilation.
