e77c8f6f3b media: sun6i-csi: Get bridge subdev directly in capture stream ops
The remote subdev connected to the capture video device is always
our bridge, so get the bridge subdev directly instead of using a
dedicated helper (which is removed by this commit).

9ff5d37ceb media: sun6i-csi: Configure registers from format tables
Switch over to using the static format table descriptions to configure
registers. Rework the hardware configuration helpers to leverage
information from the format structures and benefit from their logic.
Remove the previous dedicated helpers.

The intention is to make the interaction between the different formats
and the hardware side more visible and clear.

b3a07d8e3e media: sun6i-csi: Rework register definitions, invert misleading fields
This cleans up the register definitions a bit, adds a prefix, remove masks.
Registers are now fully defined, some additional fields were added when
needed. New format definitions are added for future use.

Some fields are wrongly defined (inverted) in Allwinner literature
(e.g. field vs frame prefixes), which is quite misleading. They are
now corrected to reflect their actual behavior.

b86f6ea010 media: sun6i-csi: Add capture state using vsync for page flip
The current implementation requires up to 3 buffers to properly
implement page flipping without losing frames: one is configured
before the video stream is started, one just after that and page
flipping is synchronized to the frame done interrupt. The comment in
the code mentions that "CSI will lookup the next dma buffer for next
frame before the current frame done IRQ triggered".

Based on observations of the CSI unit behavior, it seems that the
buffer DMA address is sampled when the frame scan begins (in addition
to starting the stream), which corresponds to the vblank interrupt
that hits just before the frame-done interrupt of the previous frame.

As a result, the address configured at the frame done interrupt is not
actually used for the next frame but for the one after that.

This proposal changes the page flipping sync point to the vsync
interrupt, which allows the DMA address to be sampled for the next
frame instead and allows operating with only two buffers.

In addition to the change in the sync point, the code is refactored
to introduce a notion of state that clarifies tracking of the buffers
with tidy functions.

0d2b746b1b media: sun6i-csi: Add bridge v4l2 subdev with port management
Introduce a bridge v4l2 subdev to prepare for separation between the
processing part (bridge) and the dma engine, which is required to
properly support ths isp workflow later on.

Currently the bridge just manages fwnode mapping to media pads,
using an async notifier (which was previously in the main code).
The s_stream video op just forwards to the connected v4l2 subdev
(sensor or MIPI CSI-2 bridge).

The video capture device is now registered after the bridge and
attaches to it with a media link.

6b2a01c90e media: i2c: ov9282: Correct HTS register for configured pixel rate
The calculations from pixel rate, width+hblank, and height+vblank
do not give the correct framerate - it's half the speed it should
be.

The datasheet lists the default for the TIMING_HTS registers (0x380c/d)
as being 0x2d8 (728) which is less than the width of the image, so
the units clearly can't be pixels.
If TIMING_HTS is considered to be units of 2-pixels, then the
resulting value of 0x5b0 (1456) makes all the calculations correct.

This driver is reporting an HBLANK value of 250, with an image width
of 1280, so TIMING_HTS is 1530 (0x5fa) pixels. However it was also
setting the register to 0x5fa, thereby not taking into account it
being units of 2-pixels.

Correct the register value to 0x2fd so that all the timing calculations
give the correct results.

105c3bc0b3 media: dt-bindings: ov5645: Convert OV5645 binding to a schema
Convert the simple OV5645 Device Tree binding to json-schema.

The previous binding marked the below properties as required which was a
driver requirement and not the device requirement so just drop them from
the required list during the conversion.
- clock-frequency
- enable-gpios
- reset-gpios

Also drop the "clock-names" property as we have a single clock source for
the sensor and the driver has been updated to drop the clk referencing by
name.

Now that the driver has been updated to drop fetching the clk reference by
name we no longer need the clock-names property in the ov5645 sensor node.

This is in preparation for removal for clock-names property from the DT
binding.

63575dd3d9 media: i2c: imx412: Assign v4l2 device subname based on compat string
imx412 and imx577 return the same chip-id when interrogated via i2c.
I've confirmed this myself by

Sakari suggested we should add a new compat which should be reflected in
the name of the media entity

https://patchwork.kernel.org/project/linux-media/patch/20220607134057.2427663-3-bryan.odonoghue@linaro.org/#24894500

Set up the .data parameter of of_device_id to pass a string which
we use to set the media entity name. Once done we can add in imx577 as a
compatible chips with the media names reflecting the directed compat string.
