855228f7d5 ipa: rkisp1: Use IPAConfig in IPA::configure()
The RkISP1 implementation of IPA::configure() still uses the legacy
interface where sensor controls (and eventually lens controls) are
passed from the pipeline handler to the IPA in a map.

Since the introduction of mojom-based IPA interface definition, it is
possible to define custom data types and use them in the interface
definition between the pipeline handler and the IPA.

Align the RkISP1 IPA::configure() implementation with the one in the
IPU3 IPA module by using a custom data type instead of relying on a map
to pass controls to the IPA.

29d6d0e93b libcamera: Move IPA sensor controls validation to CameraSensor
The CameraSensor class validates that the sensor driver in use supports
the controls required for IPA modules to work correctly.

For in-tree IPA modules, whose pipeline handlers already use
CameraSensor there's no need to validate such controls again.

Remove controls validation from the IPU3 and RkISP1 IPA modules and rely
on CameraSensor doing that at initialization time.

The list of mandatory controls is expanded to add V4L2_CID_ANALOGUE_GAIN
without which IPA modules cannot function.

The new requirement only applies to RAW sensors, platforms like UVC and
Simple are not impacted by this change.

While at it, expand the sensor driver requirements documentation to
include V4L2_ANALOGUE_GAIN in the list of mandatory controls a sensor
driver has to support.

a857a150e1 pipeline: raspberrypi: Remove enum BuffferMask from the mojom interface
The BufferMask enum provides a way of identifying which stream a frame buffer
belongs to. This enum is defined in the raspberrypi.mojom interface file.
However, the IPA does not need these enum definitions to mmap buffers that it
uses.

Move this enum out of the raspberrypi.mojom interface file and put it into
the RPi namespace visible only to the pipeline handler. This removes the
need to include the auto-generated IPA interface header in the RPi::Stream
definition.

820607b195 pipeline: raspberrypi: Update naming convention for tuning files
Append "_mono" to the sensor name when generating the tuning filename for
monochrome sensor variants. So the new naming convention is as follows:

<sensor_name>.json - Standard colour sensor variant
<sensor_name>_mono.json - Monochrome sensor variant

Rename the existing imx296.json file to imx296_mono.json as this tuning file
is based on the monochrome variant of the IMX296.

351abecdb9 ipa: ipu3: Correct context during configure()
The introduction of the FCQueue in the IPU3 inadvertently introduced a
bug which cleared the initialisation of the session configuration
immediately after some parameters had been set.

Furthermore, it cleared and never re-initialised the sensor line
duration property, which was previously only set during the call to
init().

Move the clearing of the contexts from the updateSessionConfiguration()
call to the earliest opportunity in configure(), and immediately
re-initialise the sensor parameters.

Bug: https://bugs.libcamera.org/show_bug.cgi?id=151
Fixes: 85c5c47325 ("ipa: ipu3: Use the FCQueue")

79f0fc937d ipa: rkisp1: Remove initialized_ flags from algorithms
Multiple algorithms have an initialized_ flag that they set to true at
the end of the init() function, and check at the beginning of prepare()
to skip preparation. This serves no real purpose, as the flag can only
be false if init() fails, in which case the IPA module initialization as
a whole will fail.

Drop the initialized_ flags.

2f1efe50a9 ipa: rkisp1: awb: Remove bias from gain calculation
The red and blue gains are computed by dividing the green mean by the
red and blue means respectively. An offset of 1 is added to the dividers
to avoid divisions by zero. This introduces a bias in the gain values.
Fix it by clamping the divisors to a minimum of 1.0 instead of adding an
offset.

7dc60a5a27 ipa: rkisp1: awb: Clamp gains to prevent divisions by zero
The gain values are currently clamped to the range [0.0, 3.996] used by
the hardware. A zero value makes little sense, as it would completely
remove the contribution of the corresponding color channel from the AWB
accumulators, but worse, would lead to divisions by zero when
calculating the raw means in subsequent iterations. Prevent this by
setting the minimum gain value to 1/256.

While at it, clamp the gain values before filtering them, to improve the
stability of the control loop.
