Add supports for the G/S_PARM V4L2 ioctls for encoder video device with
necessary hooks. This allows userspace to query the current streaming
parameters such as frame intervals and set desired streaming parameters
primarily the frame rate.

Previously, the format validation relied on an array of supported
formats, which only listed formats for the OUTPUT plane. This caused
failures when validating formats for the CAPTURE plane.
Update the check to validate against the only supported format on the
CAPTURE plane, which is NV12.

Improve drain handling by ensuring the LAST flag is attached to final
capture buffer when drain response is received from the firmware.
Previously, the driver failed to attach the V4L2_BUF_FLAG_LAST flag when
a drain response was received from the firmware, relying on userspace to
mark the next queued buffer as LAST. This update fixes the issue by
checking the pending drain status, attaching the LAST flag to the
capture buffer received from the firmware (with EOS attached), and
returning it to the V4L2 layer correctly.

For HFI Gen1, the instances substate is changed to LOAD_RESOURCES only
when a START command is issues to the firmware. If STOP is called
without a prior START, the firmware may reject the command and throw
some erros.

Remove earlier complex conditional checks in the non-streaming path that

started. These explicit checks are redundant, as vb2 already ensures
that stop is only called on ports that have been started, maintaining

Currently, internal buffers are destroyed only if 'PENDING_RELEASE' flag
is set when a release response is received from the firmware, which is
incorrect. Internal buffers should always be destroyed when the firmware
explicitly releases it, regardless of whether the 'PENDING_RELEASE' flag
was set by the driver. This is specially important during force-stop
scenarios, where the firmware may release buffers without driver marking
them for release.
Fix this by removing the incorrect check and ensuring all buffers are
properly cleaned up.

A client (e.g., GST for encoder) can initiate streaming on the capture
port before the output port, causing the instance state to transition to
OUTPUT_STREAMING. When streaming is subsequently started on the output
port, the instance state advances to STREAMING, and the substate should
transition to LOAD_RESOURCES.
Previously, the code blocked the substate transition to LOAD_RESOURCES
if the instance state was OUTPUT_STREAMING. This update modifies the
logic to permit the substate transition to LOAD_RESOURCES when the
instance state is OUTPUT_STREAMING, thereby supporting this client
streaming sequence.

The previous check to block capture port streaming before output port
was incorrect and caused some valid usecase to fail. While removing that
check allows capture port to enter streaming independently, it also
introduced firmware errors due to premature queuing of DPB buffers
before the firmware session was fully started which happens only when
streamon is called on output port.
Fix this by deferring DPB buffer queuing to the firmware until both
capture and output are streaming and state is 'STREAMING'.

Nitin Rawat <nitin.rawat@oss.qualcomm.com> says:
The patch series simplifies the UFS MCQ (Multi Circular Queue)
resource mapping in the Qualcomm UFS host controller driver by
replacing the complex multi-resource approach with a streamlined
single-resource implementation.
The current MCQ implementation uses multiple separate resource
mappings (RES_UFS, RES_MCQ, RES_MCQ_SQD, RES_MCQ_VS) with dynamic
resource allocation, which increases code complexity and potential for
resource mapping errors. This approach also doesn't align with the
device tree binding specification that defines a single 'mcq' memory
region.
Replace the multi-resource mapping with a single "mcq" resource that
encompasses the entire MCQ configuration space. The doorbell registers
(SQD, CQD, SQIS, CQIS) are accessed using predefined offsets relative
to the MCQ base address, providing clearer memory layout organization.
Tested on Qualcomm platforms SM8650 and SM8750 with UFS MCQ enabled.
Changes from v3:
1. Addressed Krzysztof comment to separate device tree and driver
patch independently in different patch series. This series caters
driver changes.
2. Addressed Manivannan's change to update commit text and remove
redundant null check in mcq code.
3. Addressed Manivannan's to Update few offsets as fixed definition
instead of enum.
Changes from v2:
1. Removed dt-bindings patch as existing binding supports required
reg-names format.
2. Added patch to refactor MCQ register dump logic for new resource
mapping.
3. Added patch to remove unused ufshcd_res_info structure from UFS core.
4. Changed reg-names from "ufs_mem" to "std" in device tree patches.
5. Reordered patches with driver changes first, then device tree changes.
6. Updated SM8750 MCQ region size from 0x2000 to 0x15000

Refactor MCQ register dump to align with the new resource mapping. As
part of refactor, below changes are done:
- Update ufs_qcom_dump_regs() function signature to accept direct
base address instead of resource ID enum
- Modify ufs_qcom_dump_mcq_hci_regs() to use hba->mcq_base and
calculated addresses from MCQ operation info
- Replace enum ufshcd_res with direct memory-mapped I/O addresses
Additionally remove the ufshcd_res_info structure and associated enum
ufshcd_res definitions from the UFS host controller header. These were
previously used for MCQ resource mapping but are no longer needed
following recent refactoring to use direct base addresses instead of
multiple separate resource regions.

The current MCQ resource configuration involves multiple resource
mappings and dynamic resource allocation.
Simplify the resource mapping by directly mapping the single "mcq"
resource from device tree to hba->mcq_base instead of mapping multiple
separate resources (RES_UFS, RES_MCQ, RES_MCQ_SQD, RES_MCQ_VS).
It also uses predefined offsets for MCQ doorbell registers (SQD, CQD,
SQIS, CQIS) relative to the MCQ base,providing clearer memory layout
clarity.
Additionally update vendor-specific register offset UFS_MEM_CQIS_VS
offset from 0x8 to 0x4008 to align with the hardware programming guide.
The new approach assumes the device tree provides a single "mcq"
resource that encompasses the entire MCQ configuration space, making the
driver more maintainable and less prone to resource mapping errors.
The change aligns the driver implementation with the device tree binding
specification, which defines a single 'mcq' memory region rather than
multiple separate regions.

The 88e1510 PHY has an erratum where the phy downshift counter is not
cleared after phy being suspended(BMCR_PDOWN set) and then later
resumed(BMCR_PDOWN cleared). This can cause the gigabit link to
intermittently downshift to a lower speed.
Disabling and re-enabling the downshift feature clears the counter,
allowing the PHY to retry gigabit link negotiation up to the programmed
retry count times before downshifting. This behavior has been observed
on copper links.

ptp: add pulse signal loopback support for debugging
Some PTP devices support looping back the periodic pulse signal for
debugging. For example, the PTP device of QorIQ platform and the NETC v4
Timer has the ability to loop back the pulse signal and record the extts
events for the loopback signal. So we can make sure that the pulse
intervals and their phase alignment are correct from the perspective of
the emitting PHC's time base. In addition, we can use this loopback
feature as a built-in extts event generator when we have no external
equipment which does that. Therefore, add the generic debugfs interfaces
to the ptp_clock driver. The first two patch are separated from the
previous patch set [1]. The third patch is new added.

The NETC Timer supports looping back the output pulse signal of Fiper-n
into Trigger-n input, so that users can leverage this feature to validate
some other features without external hardware support. For example, users
can use it to test external trigger stamp (EXTTS). And users can combine
EXTTS with loopback mode to check whether the generation time of PPS is
aligned with an integral second of PHC, or the periodic output signal
(PTP_CLK_REQ_PEROUT) whether is generated at the specified time.
Since ptp_clock_info::perout_loopback() has been added to the ptp_clock
driver as a generic interface to enable or disable the periodic output
signal loopback, therefore, netc_timer_perout_loopback() is added as a
callback of ptp_clock_info::perout_loopback().
Test the generation time of PPS event:
$ echo 0 1 > /sys/kernel/debug/ptp0/perout_loopback
$ echo 1 > /sys/class/ptp/ptp0/pps_enable
$ testptp -d /dev/ptp0 -e 3

than each vendor having a different implementation.

$ cat /sys/kernel/debug/ptp<N>/n_perout_loopback
Enable the loopback of the periodic output signal of channel X:
$ echo <X> 1 > /sys/kernel/debug/ptp<N>/perout_loopback
