media: hantro: Use core-generated bus_info value
The Hantro driver uses a hardcoded value for the bus_info field in the
media device and |struct v4l2_capability|. This worked well when there
was just one device. However with the iMX.8 series we are now seeing
two Hantro blocks on the same chip. The static bus_info is no longer
sufficient for differentiating devices.
Since commit
f2d8b6917f3b ("media: v4l: ioctl: Set bus_info in
v4l_querycap()"), the V4L2 core provides a default value for the
bus_info field for platform and PCI devices. This value will match
the default value for media devices added by commit
cef699749f37
("media: mc: Set bus_info in media_device_init()"). These defaults
are stable and device-specific.

Size: Stepwise 0x0 - 0x0 with step 0/0
Before this change, the driver would return EINVAL, which is also invalid
but worked in GStreamer. The original intent was not to implement it, hence
the -ENOTTY return in this change. While drivers should implement
ENUM_FRMSIZE for all formats and queues, this change is limited in scope to
fix the regression.

media: i2c: ov5670: Handle RO controls in set_ctrl
The ov5670 driver registers three controls as read-only:
- V4L2_CID_PIXEL_RATE
- V4L2_CID_LINK_FREQ
- V4L2_CID_HBLANK
The driver updates the range of HBLANK with __v4l2_ctrl_modify_range()
and updates the values of PIXEL_RATE and LINK_FREQ with an
explicit call to __v4l2_ctrl_s_ctrl() in ov5670_set_pad_format() time.
This causes the .set_ctrl handler to be called on these controls
causing a non-fatal warning to be emitted:
ov5670_set_ctrl Unhandled id:0x9e0902, val:0x824
This is currently only critical for HBLANK, as LINK_FREQ and PIXEL_RATE
currently only support a single value, and the v4l2-ctrl framework skips
calling .set_ctrl() if the current control value is not changed.
Expand the ov5670_set_ctrl() callback to handle the above controls
to remove the above warning and defend against future expansions
of the supported pixel rates and link frequencies.
Also be stricter and return an error value if a control is actually not
handled.

Using the special 2x2 analog binning mode fixes the issue, but causes
artefacts for RAW10 1232p capture. So here we choose the binning mode
depending upon the frame format selected.
As both binning modes work fine for 480p RAW8 and RAW10 capture, it can
share the same code path as 1232p for selecting binning mode.

media: ov5640: Fix analogue gain control
Gain control is badly documented in publicly available (including
leaked) documentation.
There is an AGC pre-gain in register 0x3a13, expressed as a 6-bit value
(plus an enable bit in bit 6). The driver hardcodes it to 0x43, which
one application note states is equal to x1.047. The documentation also
states that 0x40 is equel to x1.000. The pre-gain thus seems to be
expressed as in 1/64 increments, and thus ranges from x1.00 to x1.984.
What the pre-gain does is however unspecified.
There is then an AGC gain limit, in registers 0x3a18 and 0x3a19,
expressed as a 10-bit "real gain format" value. One application note
sets it to 0x00f8 and states it is equal to x15.5, so it appears to be
expressed in 1/16 increments, up to x63.9375.
The manual gain is stored in registers 0x350a and 0x350b, also as a
10-bit "real gain format" value. It is documented in the application
note as a Q6.4 values, up to x63.9375.
One version of the datasheet indicates that the sensor supports a
digital gain:
The OV5640 supports 1/2/4 digital gain. Normally, the gain is
controlled automatically by the automatic gain control (AGC) block.
It isn't clear how that would be controlled manually.
There appears to be no indication regarding whether the gain controlled
through registers 0x350a and 0x350b is an analogue gain only or also
includes digital gain. The words "real gain" don't necessarily mean
"combined analogue and digital gains". Some OmniVision sensors (such as
the OV8858) are documented as supoprting different formats for the gain
values, selectable through a register bit, and they are called "real
gain format" and "sensor gain format". For that sensor, we have (one of)
the gain registers documented as
0x3503[2]=0, gain[7:0] is real gain format, where low 4 bits are
fraction bits, for example, 0x10 is 1x gain, 0x28 is 2.5x gain
If 0x3503[2]=1, gain[7:0] is sensor gain format, gain[7:4] is coarse
gain, 00000: 1x, 00001: 2x, 00011: 4x, 00111: 8x, gain[7] is 1,
gain[3:0] is fine gain. For example, 0x10 is 1x gain, 0x30 is 2x gain,
0x70 is 4x gain
(The second part of the text makes little sense)
"Real gain" may thus refer to the combination of the coarse and fine
analogue gains as a single value.
The OV5640 0x350a and 0x350b registers thus appear to control analogue
gain. The driver incorrectly uses V4L2_CID_GAIN as V4L2 has a specific
control for analogue gain, V4L2_CID_ANALOGUE_GAIN. Use it.
If registers 0x350a and 0x350b are later found to control digital gain
as well, the driver could then restrict the range of the analogue gain
control value to lower than x64 and add a separate digital gain control.

Helper functions are needed to read and set pixel and link frequencies
which also reduces the number of fixed registers in the table of modes.

media: i2c: imx219: Split common registers from mode tables
There are four modes, and each mode has a table of registers.
Some of the registers are common to all modes, so create new
tables for these common registers to reduce duplicate code.

media: i2c: tc358746: fix possible endianness issue
Using the u64 v4l2_dbg_register.val directly can lead to unexpected
results depending on machine endianness. Fix this by using a local
variable which is assigned afterwards. Since tc358746_read() will init
the val variable to 0 we can assing it without checking the return value
first.
