When user space detects an error or does not receive
response for a request, Lets do a reset(LDAR) is triggered.
Before LDAR, user space sends flush command to the
kernel space.
In order to debug the cause for this situation and to dump
the information, user space sends a dump command to
kernel space before sending flush.
As a part of this command, it passes the culprit request id
and the buffer into which the information can be dumped.
Kernel space traverses across the drivers and find the culprit hw
and dumps the relevant information in the buffer.
This data is written to a file for offline processing.
This commit dumps the IFE, CSID registers, LUT tables and context
information, cmd buffers, timestamps information for
submit, apply, RUP, epoch and buffdones of the last 20
requests.

While processing the user space submitted isp packet,
isp context need to know the packet opcode.
Get the opcode from the hw manager than the direct accessing the
opcode from packet.
Ife umd sends different opcodes then tfe umd. Both ife and tfe kernel
packet opcodes are same. So hw manager can consume this differences.

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.

about the request status being served. If before clearing
the IRQ, the value of userdata register gets updated, then

This change will make sure that another interrupt is fired
by clearing the IRQ first and reading the userdata later.

Reset the slot with the valid request on receiving
the buf_done which is reported on next EPOCH.
In case of back to back irqs slot is marked as skip idx
it will apply the request and try to reset a slot based
on MAX_PD + 1 calculation which might have the request
for which we have got a bubble. To make sure this does not
happen, reset a slot only on the buf_done for valid request.
If STOP ioctl is called from UMD for ISP, it will flush all
the lists. But this is not notified to CRM which might have
a stale entry of the half applied request, so on STOP ioctl
clear all the slots.
In case of SAT mode if one of the link has generated bubble,
while the sync_link has the sync_request slot reset sync_link
will not let the link recover of the bubble. To make sure the
recovery sync_mode is set to 0 for two consecutive slots of
the link.

With old register space, handling new features and operations
would have been a complex task. This change takes care of old

register's access to CDM.
This change further adds support for "arbitration" in case of
multi-context CDMs.
Exports reset functionality to clients, detection of CDM hang.
Flushing the CDM requests and dumping the FIFO content for all
contexts.
It also adds submitting "debug_gen_irq" as BL_done IRQ is only
an indication for availability of FIFO's. The AHB operations
are completed can only be known if the added "debug_gen_irqs"
gets executed and are received by the CDM.

For some targets, there is a requirement to have the lower IFE
as master. Current implementation selects the higher IFE as
the master.
This commit changes the acquire logic to reserve the lower IFE
first and then the higher IFE as slave. This logic is for dual
ife use cases. For single IFE use case, acquire logic is not
changed.
Also, removes the hard coded check for master hw index
during the irq handling. Stores the master hw index
in ife hardware manager context and check against it.
