Subject: [PATCH] media: i2c: imx290: Support for the Sony IMX290
sensor
media: i2c: imx290: set the format before VIDIOC_SUBDEV_G_FMT is called
Commit d46cfdc86c30d5ec768924f0b1e2683c8d20b671 upstream.
With the current driver 'media-ctl -p' issued right after the imx290 driver
is loaded prints:
pad0: Source
[fmt:unknown/0x0]
The format value of zero is due to the current_format field of the imx290
struct not being initialized yet.
As imx290_entity_init_cfg() calls imx290_set_fmt(), the current_mode field
is also initialized, so the line which set current_mode to a default value
in driver's probe() function is no longer needed.

media: i2c: imx290: Add support for 74.25MHz clock
The existing driver only supported a clock of 37.125MHz, but the
sensor also supports 74.25MHz.
Add the relevant register modifications to support this alternate
clock frequency.

media: i2c: imx290: Correct range for V4L2_CID_GAIN to 0-238
The datasheet lists the gain as being 0.0 to 72.0dB in 0.3dB steps, which
makes 238 steps total.
Correct the 0-72 range defined in the driver.

media: i2c: imx290: Convert HMAX setting into V4L2_CID_HBLANK
Userspace needs to know HBLANK if it is to work out exposure times
and frame rates, therefore convert it to map onto V4L2_CID_HBLANK
Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
media: i2c: imx290: Add support for V4L2_CID_VBLANK
In order to calculate framerate and durations userspace needs
the vertical blanking information. This can be configurable,
and indeed the datasheet lists different values for VBLANK for
the 1080p and 720p modes.
Add the new control, and adopt the datasheet values for each mode.
Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
media: i2c: imx290: Add exposure control to the driver.
Adds support for V4L2_CID_EXPOSURE so that userspace can control
the sensor exposure time.
Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
media: i2c: imx290: Add H and V flip controls
The sensor supports horizontal and vertical flips, so support them
through V4L2_CID_HFLIP and V4L2_CID_VFLIP.
This sensor does NOT change the Bayer order when changing the
direction of readout, therefore no special handling is required for
that.

media: dt-bindings: media: i2c: Add mono version to IMX290 bindings
The IMX290 module is available as either monochrome or colour and
the variant is not detectable at runtime.

media : i2c: imx290: Add support for the mono sensor variant.
The IMX290 module is available as either mono or colour (Bayer).
Update the driver so that it can advertise the correct mono
formats instead of the colour ones.

media: i2c: imx290: Switch set_hmax to use imx290_write_buffered_reg
imx290_set_hmax was using two independent writes to set up hmax,
when all other multi-register writes were using imx290_write_buffered_reg
which claims the group hold first.
Switch imx290_set_hmax to using imx290_write_buffered_reg too.

media: i2c: imx290: Set the colorspace fields in the format
The colorspace fields were left untouched in imx290_set_fmt
which lead to a v4l2-compliance failure.

media: i2c: imx290: Replace V4L2_CID_GAIN with V4L2_CID_ANALOGUE_GAIN
Most software (including libcamera) requires V4L2_CID_ANALOGUE_GAIN,
not V4L2_CID_GAIN.
The range for the control is 0 to 100 for which the sensor uses only
analogue gain; higher values would involve digital gain which this
control should not apply.

media: i2c: imx290: Handle exposure correctly when vblank changes
When vblank changes we must modify the exposure range. Also, with this
sensor, the effective exposure time implicitly changes when vblank
does, so we have to reset it after every vblank update.

media: i2c: imx290: Support 60fps in 2 lane operation
Commit "97589ad61c73 media: i2c: imx290: Add support for 2 data lanes"
added support for running in two lane mode (instead of 4), but
without changing the link frequency that resulted in a max of 30fps.
Commit "98e0500eadb7 media: i2c: imx290: Add configurable link frequency
and pixel rate" then doubled the link frequency when in 2 lane mode,
but didn't undo the correction for running at only 30fps, just extending
horizontal blanking instead.
It also didn't update the CSI timing registers in accordance with the
datasheet.
Remove the 30fps limit on 2 lane by correcting the register config
in accordance with the datasheet for 60fps operation over 2 lanes.
Frame rate control (via V4L2_CID_VBLANK or HBLANK) can still reduce
the frame rate on 2 lanes back to 30fps.

media: i2c: imx290: Fix the pixel rate at 148.5Mpix/s
Whilst the datasheet lists the link frequency changing between
1080p and 720p modes, reality is that with the default blanking
we have
(1920 + 280) * (1080 + 45) * 60fps = 148.5MPix/s
and
(1280 + 2020) * (720 + 30) * 60fps = 148.5MPix/s
and this reflects reality whether in 10 or 12 bit readout modes.
How this relates to link frequency is unclear as it differs
from the datasheet, but all exposure and frame rate calcs need
the pixel rate to be correct, so make it so.

media: i2c: imx290: Fix clock setup register assignments
When the clock setups were added for the alternate external clocks,
the settings for 2 lane 720p and 4 lane 1080p were transposed.
2 lane 720p still worked, but 4 lane 1080p didn't.
Correct the assignments.

IMX327 is the previous generation to IMX290, and supports up to 1080p60
as 10 or 12 bit.
IMX290 adds 1080p120 in 10 bit mode.
IMX462 adds 1080p120 in both 10 and 12 bit modes.

media: i2c: imx290: Updating VBLANK should update exposure in all states
The code to update the range of the exposure control was after a
check that the sensor was powered up. This is incorrect as the
range should be updated under all conditions.
Move the range update code to the correct place.

media: i2c: imx290: Drop incorrect comment about pixelrate
commit b5eca6fd4284 ("media: i2c: imx290: Fix the pixel rate at 148.5Mpix/s")
corrected imx290_calc_pixel_rate to always return the correct
pixle rate of 148.5Mpix/s, but didn't remove the comment that said
it relied on some other parameters.
Drop that comment.

media: i2c: imx290: Do not reset exposure time from set_fmt
V4L2 controls are meant to be persistent, and only altered if
the values break hardware constraints.
In imx290_set_fmt the CID_VBLANK parameter was being reset to
the mode default, and therefore the maximum exposure value
potentially also changed.
VBLANK is no longer reset, and even if it is, then the set_ctrl
that will be called will alter the range for the exposure
control. Therefore there is no need to reset the exposure time
from set_fmt.
Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
media: i2c: imx290: Correct min HBLANK.
In the 720p mode the CSI link is run at a lower frequency, and
the minimum HBLANK value has to be increased to avoid generating
more data from the sensor than the link can carry.
Set the minimum based on the mode.
