Add to each mode supported by the sensor the ideal pixel rate, as
defined by Table 2.1 in the chip manual.
The ideal pixel rate will be used to compute the MIPI CSI-2 clock tree.

The array of supported modes is close to unreadable.
Re-arrange it giving it some room to breath.
Cosmetic change only.

Checking if the sensor is used in DVP or MIPI CSI-2 mode is a repeated
pattern which is about to be repeated more often.
Provide an inline function to shortcut that.

After having set a new format re-calculate the pixel_rate and link_freq
control values and update them when in MIPI mode.
Take into account the limitation of the link frequency having to be
strictly smaller than 1GHz when computing the desired link_freq, and
adjust the resulting pixel_rate acounting for the clock tree
configuration.

Re-work the ov5640_set_mipi_pclk() function to calculate the
PLL configuration using the pixel_rate and link_freq values set at
s_fmt time.
Rework the DVP clock mode settings to calculate the pixel clock
internally and remove the assumption on the 16bpp format.
Tested in MIPI CSI-2 mode with 1 and 2 data lanes with:
- all the sensor supported resolutions in UYVY, RGB565 and MJPEG formats.
- resolutions >= 1280x720 in RAW Bayer format.
- resolutions < 1280x720 in RGB888 format.

From: Jacopo Mondi @ 2022-05-13 14:13 UTC (permalink / raw)
To: sakari.ailus, mchehab, linux-media
The current definition of a sensor mode defines timings as follows:
- hact, vact: Visible width and height
- htot, vtot: Total sizes including blankings
This makes difficult to clearly separate the visible sizes from the
blankings and to make the vertical blanking programmable.
Rework the sensor modes sizes definition to:
- Report the analog crop sizes
- Report the visible crop size
- Report the total pixels per line as HBLANK is fixed
- Report the VBLANK value to make it programmable
Also modify the ov5640_set_timings() function to program all the
windowing registers are remove them from the per-mode register-value
tables.
Do not change the timing values from the ones reported in the register
tables to maintain bisectability.

Adjust the left crop of 720x480 to enable capture in RGB888 format,
which is otherwise broken.
The 56 pixels alignment has been copied from the 720x576 mode.

Separate the timings for the DVP mode from the timings for the CSI-2
mode in the ov5640 modes definition.
The CSI-2 timings will deviate from the DVP ones as the clock tree is
calculated differently.
In CSI-2 mode change the analog crop rectangles as the OV5640 pixel
array is composed as:
- vertically: 16 dummy columns, 2592 valid ones and 16 dummy columns for
a total of 2624 columns
- horizontally: 8 optical black lines, 6 dummy ones, 1944 valid and 6
dummies for a total of 1964 lines
Adjust the analog crop rectangle in CSI-2 mode to:
- Skip the first 16 dummy columns
- Skip the first 14 black/dummy lines
- Pass the whole valid pixel array size to the ISP for all modes except
1024x768, 720p and 1080p which are obtained by cropping the valid pixel
array.
Tested in RGB565, UYVY and RGB888 modes in CSI-2 mode.

The register tables for all resolutions smaller than 720p are now
identical.
Remove the duplicated ones and create a single ov5640_setting_low_res[]
register table.

The ov5640_mode_init_data is a fictional sensor more which is used to
program the initial sensor settings.
It is only used to initialize the sensor and can be replaced
it with a throw-away mode which just wraps the register table.
Also rename the register table to drop the format from the name to make
it clear an actual sensor mode has to be applied after the initial
programming.

Add the HBLANK control as read-only.
The hblank value is fixed in the mode definition and is updated
everytime a new format is applied.

Add the VBLANK control which allows to select the duration of the
frame vertical blankings and allows to control the framerate.
The VBLANK control also modifies the exposure time range, which cannot
exceed the maximum frame length.

From: Hugues Fruchet <hugues.fruchet@st.com>
Adjust the vertical blanking when s_frame_interval is used.
s_frame_interval allows to set a fixed frame rate, which gets stored as
the sensor's current one. When a new mode is applied, the current frame
rate is reset to the mode's default one. In order to correctly report
the currently configured vertical blanking for s_frame_interval users,
verify that the desired frame rate has not been changed. If that's the
case, compute the correct blanking value and reflect it through the
corresponding v4l2 control.

The current implementation of ov5640_find_mode() fails if the
frame rate programmed with s_frame_interval doesn't match the
maximum frame rate for the current mode.
This causes issues when moving from one mode with higher FPS to another
one which only supports a lower FPS range with tools like media-ctl.
It also forces users that do not use s_frame_interval(), but rather
configure blankings explicitly, to adjust the programmed FPS range to
avoid failures.
For this reason, remove the FPS check from ov5640_find_mode() and only
perform it at s_frame_interval() time.

Now that the frame duration can be controlled by tuning the VBLANK
duration in CSI-2 mode, fix all modes definitions to comply with the
reported FPS.
All modes run at 30 FPS except for full-resolution mode 2592x1944
which runs at 15FPS.
Tested on a 2 data lanes setup in UYVY and RGB565 modes in CSI-2 mode.

V4L2 controls using v4l2_ctrl_new_fwnode_properties().
Remove the open-coded parsing of the rotation property and assume the
DTS is correct is providing either <0> or <180> as possible rotations.

The driver already supports the 2X8_[LE|BE] variants of RGB565
formats.
As for CSI-2 the 2X8 variants do not apply, add RGB565_1X16 variant
with little-endian ordering of components as required by the CSI-2
specifications.

Add support for BGR888 image format.
No existing media bus codes describe exactly the way data is transferred
on the CSI-2 bus. This is not a new issue, the CSI-2 YUV422 8-bit format
is described by MEDIA_BUS_FMT_UYVY8_1X16 which is an arbitrary
convention and not an exact match. Use the MEDIA_BUS_FMT_BGR888_1X24 to
follow the same convention, based on the order in which bits are
transmitted over the CSI-2 bus when producing images in RGB24 format.

The ov5640 driver supports different sizes for different mbus_codes.
In particular:
- 8bpp modes: high resolution sizes (>= 1280x720)
- 16bpp modes: all sizes
- 24bpp modes: low resolutions sizes (< 1280x720)
Restrict the frame sizes enumerations to the above constraints.
While at it, make sure the fse->mbus_code parameter is valid, and return
-EINVAL if it's not.

The format enumeration list is shared between CSI-2 and DVP modes.
This lead to the enumeration of unsupported format variants in both
modes.
Separate the list of DVP and CSI-2 formats and create helpers to access
the correct one.

The image format produced by the sensor is controlled by two registers,
whose values computation is open coded in ov5640_set_framefmt().
As we have a list of formats already, move the OV5640_REG_FORMAT_CONTROL00
and OV5640_REG_ISP_FORMAT_MUX_CTRL register values to the static list
of formats instead of open coding it.
