fc0f5b59ad media: atomisp: csi2-bridge: Add dev_name() to acpi_handle_info() logging
acpi_handle_info() uses the ACPI path to the handle as prefix for messages
e.g. : "\_SB_.I2C2.CAM8".

This makes it hard for users to figure out which csi2-bridge messages
belong to which sensor since the actual sensor drivers uses the ACPI
device name (typically "HID:00") for logging.

Extend the acpi_handle_info() (and err and warn) logging to also log
the device name to make it easier to match csi2-bridge messages with
sensor driver log messages.

f04eedb942 media: atomisp: csi2-bridge: Switch to new common ipu_bridge_init()
Remove the duplicate IPU ACPI bridge code and use the new
shared ipu_bridge_init() functionality.

Note this will also use / assume v4l2-async device instantiation for
ov5693 sensors on atomisp devices since ipu_supported_sensors[]
already contains a match for this.

This is fine since recent atomisp improvements allow the atomisp code
to work with generic v4l2 sensor drivers and using an unmodified
drivers/media/i2c/ov5693.c has been successfully tested on
an Acer Iconia W4 820 tablet with an ISP2400 + OV5693 sensor.

8e3e916e23 media: ipu-bridge: Add a runtime-pm device-link between VCM and sensor
In most cases when a VCM is used there is a single integrated module
with the sensor + VCM + lens. This means that the sensor and VCM often
share regulators and possibly also something like a powerdown pin.

In the ACPI tables this is modelled as a single ACPI device with
multiple I2cSerialBus resources.

On atomisp devices the regulators and clks are modelled as ACPI
power-resources, which are controlled by the (ACPI) power state
of the sensor. So the sensor must be in D0 power state for the VCM
to work.

To make this work add a device-link with DL_FLAG_PM_RUNTIME flag
so that the sensor will automatically be runtime-resumed whenever
the VCM is runtime-resumed.

This requires the probing of the VCM and thus the creation of the VCM
I2C-client to be delayed till after the sensor driver has bound.

Move the instantiation of the VCM I2C-client to the v4l2_async_notifier
bound op, so that it is done after the sensor driver has bound; and
add code to add the device-link.

This fixes the problem with the shared ACPI power-resources on atomisp2
and this avoids the need for VCM related workarounds on IPU3 / IPU6.

E.g. until now the dw9719 driver needed to get and control a Vsio
(V sensor IO) regulator since that needs to be enabled to enable I2C
pass-through on the PMIC on the sensor module. So the driver was
controlling this regulator even though the actual dw9719 chip has no
Vsio pin / power-plane.

This also removes the need for ipu_bridge_init() to return
-EPROBE_DEFER since the VCM is now instantiated later.

dd671ed0c5 media: ipu-bridge: Add a ipu_bridge_parse_ssdb() helper function
The code to go from ACPI sensor info to a fwnode-tree with connector
nodes and endpoint properties is 99% the same for the atomisp2 and
the IPU3.

The main difference is that atomisp2 devices do not have a SSDB table
with various info.

Abstract out the parsing of the sensor's ACPI fwnode into a helper
function and store the parsed results, rather then the raw SSDB
in struct ipu_sensor.

This is a preparation patch for making the ipu-bridge code more generic
so that it can be shared with the atomisp driver.

11e0a7c8e0 media: ipu-bridge: Do not use on stack memory for software_node.name field
Commit 567f97bd38 ("media: ipu3-cio2: support multiple sensors and VCMs
with same HID") introduced an on stack vcm_name and then uses this for
the name field of the software_node struct used for the vcm.

But the software_node struct is much longer lived then the current
stack-frame, so this is no good.

Instead extend the ipu_node_names struct with an extra field to store
the vcm software_node name and use that.

Note this also changes the length of the allocated buffer from
ACPI_ID_LEN + 4 to 16. the name is filled with "<ipu_vcm_types[x]>-%u"
where ipu_vcm_types[x] is not an ACPI_ID. The maximum length of
the strings in the ipu_vcm_types[] array is 11 + 5 bytes for "-255\0"
means 16 bytes are needed in the worst case scenario.

613cbb91e9 media: Add MIPI CCI register access helper functions
The CSI2 specification specifies a standard method to access camera sensor
registers called "Camera Control Interface (CCI)".

This uses either 8 or 16 bit (big-endian wire order) register addresses
and supports 8, 16, 24 or 32 bit (big-endian wire order) register widths.

Currently a lot of Linux camera sensor drivers all have their own custom
helpers for this, often copy and pasted from other drivers.

Add a set of generic helpers for this so that all sensor drivers can
switch to a single common implementation.

These helpers take an extra optional "int *err" function parameter,
this can be used to chain a bunch of register accesses together with
only a single error check at the end, rather than needing to error
check each individual register access. The first failing call will
set the contents of err to a non 0 value and all other calls will
then become no-ops.

Also add documentation related files under the camera sensor entry. Add
the word "CAMERA" to the subject as well since there are many other kinds
of sensors.

11ec2c45b5 media: i2c: Remove common dependencies from sensor drivers
As selecting V4L2_FWNODE, MEDIA_CONTROLLER and VIDEO_V4L2_SUBDEV_API are
now selected by the top level menu, they can be dropped from the
individual drivers. Also dropped selecting V4L2_ASYNC for a single driver
as this is already implied by V4L2_FWNODE.

Similarly, the I2C dependency is now also in the top level menu, so remove
it, as well as VIDEO_DEV which isn't needed by camera sensor drivers.

7d3c7d2a29 media: i2c: Add a camera sensor top level menu
Select V4L2_FWNODE and VIDEO_V4L2_SUBDEV_API for all sensor drivers. This
also adds the options to drivers that don't specifically need them, these
are still seldom used drivers using old APIs. The upside is that these
should now all compile --- many drivers have had missing dependencies.

The "menu" is replaced by selectable "menuconfig" to select the needed
V4L2_FWNODE and VIDEO_V4L2_SUBDEV_API options.

Also select MEDIA_CONTROLLER which VIDEO_V4L2_SUBDEV_API effectively
depends on, and add the I2C dependency to the menu.

c2c0abbe86 MAINTAINERS: correct file entry in MEDIA DRIVERS FOR FREESCALE IMX7/8
Commit cd063027c3 ("media: imx: Unstage the imx8mq-mipi-csi2 driver")
adds a file entry for the driver code to MEDIA DRIVERS FOR FREESCALE
IMX7/8, but misses the number '2' suffix in that entry. Hence,
./scripts/get_maintainer.pl --self-test=patterns complains about a broken
reference.

Correct the file entry in MEDIA DRIVERS FOR FREESCALE IMX7/8.

VIDEO_IMX_CSI, there's no need to have separate Kconfig options. Merge

FPD-Link has an operating mode that used to be called "asynchronous" in
the hardware documentation, but that has been changed to non-synchronous
already quite a while back. The ub960 driver still had one instance of
the old naming, so let's rename it.
