d9967fa37c media: qcom: iris: Improve format alignment for encoder
Add members enc_raw_width, enc_raw_height to the struct iris_inst to
support codec alignment requirements.

HFI_PROP_RAW_RESOLUTION needs to be set to the actual YUV resolution.

2c73cfd0cf media: iris: Prevent output buffer queuing before stream-on completes
During normal playback, stream-on for input is followed by output, and
only after input stream-on does actual streaming begin. However, when
gst-play performs a seek, both input and output streams are stopped,
and on restart, output stream-on occurs first. At this point, firmware
has not yet started streaming. Queuing output buffers before the firmware
begins streaming causes it to process buffers in an invalid state, leading
to an error response. These buffers are returned to the driver as errors,
forcing the driver into an error state and stopping playback.

Fix this by deferring output buffer queuing until stream-on completes.
Input buffers can still be queued before stream-on as required.

1dabf00ee2 media: iris: gen1: Destroy internal buffers after FW releases
After the firmware releases internal buffers, the driver was not
destroying them. This left stale allocations that were no longer used,

2d0bbd982d media: iris: Add buffer to list only after successful allocation
Move `list_add_tail()` to after `dma_alloc_attrs()` succeeds when creating
internal buffers. Previously, the buffer was enqueued in `buffers->list`
before the DMA allocation. If the allocation failed, the function returned
`-ENOMEM` while leaving a partially initialized buffer in the list, which
could lead to inconsistent state and potential leaks.

By adding the buffer to the list only after `dma_alloc_attrs()` succeeds,
we ensure the list contains only valid, fully initialized buffers.

8fc707d13d media: iris: remove v4l2_m2m_ioctl_{de,en}coder_cmd API usage during STOP handling
Currently v4l2_m2m_ioctl_{de,enc}coder_cmd is being invoked during STOP
command handling. However, this is not required as the iris driver has
its own drain and stop handling mechanism in place.

Using the m2m command API in this context leads to incorrect behavior,
where the LAST flag is prematurely attached to a capture buffer,
when there are no buffers in m2m source queue. But, in this scenario
even though the source buffers are returned to client, hardware might
still need to process the pending capture buffers.

Attaching LAST flag prematurely can result in the capture buffer being
removed from the destination queue before the hardware has finished
processing it, causing issues when the buffer is eventually returned by
the hardware.

To prevent this, remove the m2m API usage in stop handling.

4980721cb9 media: iris: use fallback size when S_FMT is called without width/height
According to 4.5.1.5 of the M2M stateful decoder UAPI documentation,
providing the width and the height to S_FMT is "required only if it
cannot be parsed from the stream", otherwise they can be left as 0
and the S_FMT implementation is expected to return a valid placeholder
resolution that would let REQBUFS succeed.

iris was missing the fallback, so clients like rpi-ffmpeg wouldn't work.
Fix by adding an explicit fallback to defaults.

89f7cf3590 media: iris: Fix ffmpeg corrupted frame error
When the ffmpeg decoder is running, the driver receives the
V4L2_BUF_FLAG_KEYFRAME flag in the input buffer. The driver then forwards
this flag information to the firmware. The firmware, in turn, copies the
input buffer flags directly into the output buffer flags. Upon receiving
the output buffer from the firmware, the driver observes that the buffer
contains the HFI_BUFFERFLAG_DATACORRUPT flag. The root cause is that both
V4L2_BUF_FLAG_KEYFRAME and HFI_BUFFERFLAG_DATACORRUPT are the same value.
As a result, the driver incorrectly interprets the output frame as
corrupted, even though the frame is actually valid. This misinterpretation
causes the driver to report an error and skip good frames, leading to
missing frames in the final video output and triggering ffmpeg's "corrupt
decoded frame" error.

To resolve this issue, the input buffer flags should not be sent to the
firmware during decoding, since the firmware does not require this
information.

370e19042f Revert "media: iris: Add sanity check for stop streaming"
This reverts commit ad699fa78b.

Revert the check that skipped stop_streaming when the instance was in
IRIS_INST_ERROR, as it caused multiple regressions:

1. Buffers were not returned to vb2 when the instance was already in
   error state, triggering warnings in the vb2 core because buffer
   completion was skipped.

2. If a session failed early (e.g. unsupported configuration), the
   instance transitioned to IRIS_INST_ERROR. When userspace attempted
   to stop streaming for cleanup, stop_streaming was skipped due to the
   added check, preventing proper teardown and leaving the firmware
   in an inconsistent state.

63c072e293 media: venus: vdec: restrict EOS addr quirk to IRIS2 only
On SM8250 (IRIS2) with firmware older than 1.0.087, the firmware could
not handle a dummy device address for EOS buffers, so a NULL device
address is sent instead. The existing check used IS_V6() alongside a
firmware version gate:

    if (IS_V6(core) && is_fw_rev_or_older(core, 1, 0, 87))
        fdata.device_addr = 0;
    else
	fdata.device_addr = 0xdeadb000;

However, SC7280 which is also V6, uses a firmware string of the form
"1.0.<commit-hash>", which the version parser translates to 1.0.0. This
unintentionally satisfies the `is_fw_rev_or_older(..., 1, 0, 87)`
condition on SC7280. Combined with IS_V6() matching there as well, the
quirk is incorrectly applied to SC7280, causing VP9 decode failures.

Constrain the check to IRIS2 (SM8250) only, which is the only platform
that needed this quirk, by replacing IS_V6() with IS_IRIS2(). This
restores correct behavior on SC7280 (no forced NULL EOS buffer address).

When hfi_session_flush is issued, all queued buffers are returned to
the V4L2 driver. Some of these buffers are not processed and have
bytesused = 0. Currently, the driver marks such buffers as error even

Only capture buffers with zero payload (and not EOS) should be marked
with VB2_BUF_STATE_ERROR. The check is performed inside the non-EOS
branch to ensure correct handling.

format adjustments grouped in a single place and improve readability.

The struct dcmipp_bytecap_device embeds a cmier variable which is
actually only set once and then used in several places for interrupt
mask or interrupt enable/disable. Use the DCMIPP_CMIER_P0ALL
bitfield macro directly instead of using it through the cmier
variable.

There is also no need to mask again vcap->cmsr2 against enabled
interrupts bit since this has already been done when storing the
interrupt status into the cmsr2 variable.

adv7604 and et8ek8 sensor drivers have mixed up logical and line level
for reset/powerdown signal.  They call it a reset signal (it indeed
behaves like that), but drivers assert the reset to operate which is
clearly incorrect and relies on wrong ACTIVE_HIGH flag in the DTS.

People in discussions copy existing poor code and claim they can repeat
same mistake, so add a note to prevent that.

When DCMIPP requires only a single clock (kclk), avoid relying on its

which necessitated naming the first clock kclk. However, this breaks
backward compatibility with existing MP13 device trees that do not
specify clock names.
