04d59cc06a media: ipu6: Don't check pipeline in stream_start
A pipeline exists when start_streaming has returned so the check for
start_streaming_called is equivalent to having media_pipeline. Use
vb2_start_streaming_called() to perform the check.

779bdaad2a media: ipu6: Ensure stream_mutex is acquired when dealing with node list
The ipu6 isys driver maintains the list of video buffer queues related to
a stream (in ipu6 context streams on the same CSI-2 virtual channel) and
this list is modified through VIDIOC_STREAMON and VIDIOC_STREAMOFF IOCTLs.
Ensure the common mutex is acquired when accessing the linked list, i.e.
the isys device context's stream_mutex.

Add a lockdep assert to ipu6_isys_get_buffer_list() and switch to guard()
while at it as the error handling becomes more simple this way.

46c96eec9a media: mt9m114: Drop start-, stop-streaming sequence from initialize
Drop the start-, stop-streaming sequence from initialize.

When streaming is started with a runtime-suspended sensor,
mt9m114_start_streaming() will runtime-resume the sensor which calls
mt9m114_initialize() immediately followed by calling
mt9m114_set_state(ENTER_CONFIG_CHANGE).

This results in the following state changes in quick succession:

mt9m114_set_state(ENTER_CONFIG_CHANGE) -> transitions to STREAMING
mt9m114_set_state(ENTER_SUSPEND)       -> transitions to SUSPENDED
mt9m114_set_state(ENTER_CONFIG_CHANGE) -> transitions to STREAMING

these quick state changes confuses the CSI receiver on atomisp devices
causing streaming to not work.

Drop the state changes from mt9m114_initialize() and move
the mt9m114_initialize() call to mt9m114_start_streaming()
so that only a single mt9m114_set_state(ENTER_CONFIG_CHANGE) call
is made when streaming is started with a runtime-suspend sensor.

df0090002c media: mt9m114: Update source pad selection and format when sink pad format changes
Call mt9m114_ifp_update_sel_and_src_fmt() on sink pad format changes to
propagate these downstream.

This is necessary in 2 different scenarios:

1. When passing through RAW10 bypassing the scaler then any sink pad format
changes must be propagated to the crop/compose selections and to the source
pad format.

2. When the scaler is active, then the crop-rectangle cannot be bigger then
the sink pad format minus a 4 pixel border all around. If the sink format
change reduces the size then things also needs to be propagated downstream.

Rather then adding extra code to check for these conditions, simply always
propagate sink pad format changes downstream.

5e3c0bd3f8 media: mt9m114: Adjust IFP selections and source format when source format changes to/from RAW10
Changing the IFP source pad format to RAW10 means disabling the scaler,
which means that the crop and compose rectangles must be reset to
match the sink format size with no border.

And when changing the source pad format back from RAW10 to another format
which require demosaicing the crop and compose rectangles must be reset
to the sink format size minus a 4 pixels border all around it.

Also when changing the source pad format back from RAW10 to another format
the colorspace, ycbcr_enc and quantization need to be updated too.

Add a new mt9m114_ifp_update_sel_and_src_fmt() helper which resets all
these taking the bordersize for the new source format into account and
call this helper whenever the source pad format changes to/from RAW10.

Put the sensor back in reset on power down. Putting the sensor in reset
reduces power-consumption by putting all the data / ctrl pins in High-Z
mode. This helps save power on designs where the regulators may need to

This also ensures that the sensor is properly reset on power up,
since now the sensor will see a reset high to low transition after
the regulators have been turned on.

84359d0a5e media: mt9m114: Avoid a reset low spike during probe()
mt9m114_probe() requests the reset GPIO in output low state:

	sensor->reset = devm_gpiod_get_optional(dev, "reset", GPIOD_OUT_LOW);

and then almost immediately afterwards calls mt9m114_power_on() which does:

		gpiod_set_value(sensor->reset, 1);
		fsleep(duration);
		gpiod_set_value(sensor->reset, 0);

which means that if the reset pin was high before this code runs that
it will very briefly be driven low because of passing GPIOD_OUT_LOW when
requesting the GPIO only to be driven high again possibly directly after
that. Such a very brief driving low of the reset pin may put the chip in
a confused state.

Request the GPIO in high (reset the chip) state instead to avoid this,
turning the initial gpiod_set_value() in mt9m114_power_on() into a no-op.
and the fsleep() ensures that it will stay high long enough to properly
reset the chip.

so no need to mark it explicitly in the driver. Also, we can set the ops
to NULL to avoid checking for it in the s_ctrl implementation.

87b2b6cef2 media: i2c: ov5647: Add control of V4L2_CID_HBLANK
The driver did expose V4L2_CID_HBLANK, but as a READ_ONLY control.

The sensor only uses the HTS register to control the line length,
so convert this control to read/write, with the appropriate ranges.
Adopt the old fixed values as the minimum values permitted in each
mode to avoid issues of it not streaming.

This should allow exposure times up to ~3 seconds (up from ~1sec).

ebde37e5ef media: i2c: ov5647: Support HFLIP and VFLIP
Add missing controls for horizontal and vertical flipping.

The sensor readout mirrors in the horizontal direction by default (if
0x3821[1] = 0) which can make things unnecessarily difficult for
applications. The register table prior to this commit was setting that
bit explicitly, to achieve a normally oriented image.

Now that we have userspace controls for HFLIP, we keep the convention
and report the non-mirrored image (with 0x3821[1] = 1) as
horizontal_flip=0, and vice versa.
