Extron DA HD 4K PLUS CEC Adapter driver
=======================================
This driver is for the Extron DA HD 4K PLUS series of HDMI Distribution
Amplifiers: https://www.extron.com/product/dahd4kplusseries
The 2, 4 and 6 port models are supported.
Firmware version 1.02.0001 or higher is required.
Note that older Extron hardware revisions have a problem with the CEC voltage,
which may mean that CEC will not work. This is fixed in hardware revisions
E34814 and up.
The CEC support has two modes: the first is a manual mode where userspace has
to manually control CEC for the HDMI Input and all HDMI Outputs. While this gives
full control, it is also complicated.
The second mode is an automatic mode, which is selected if the module option
``vendor_id`` is set. In that case the driver controls CEC and CEC messages
received in the input will be distributed to the outputs. It is still possible
to use the /dev/cecX devices to talk to the connected devices directly, but it is
the driver that configures everything and deals with things like Hotplug Detect
changes.
The driver also takes care of the EDIDs: /dev/videoX devices are created to
read the EDIDs and (for the HDMI Input port) to set the EDID.
By default userspace is responsible to set the EDID for the HDMI Input
according to the EDIDs of the connected displays. But if the ``manufacturer_name``
module option is set, then the driver will take care of setting the EDID
of the HDMI Input based on the supported resolutions of the connected displays.
Currently the driver only supports resolutions 1080p60 and 4kp60: if all connected
displays support 4kp60, then it will advertise 4kp60 on the HDMI input, otherwise
it will fall back to an EDID that just reports 1080p60.
The status of the Extron is reported in ``/sys/kernel/debug/cec/cecX/status``.
The extron-da-hd-4k-plus driver implements the following module options:
``debug``
---------
If set to 1, then all serial port traffic is shown.
``vendor_id``
-------------
The CEC Vendor ID to report to connected displays.
If set, then the driver will take care of distributing CEC messages received
on the input to the HDMI outputs. This is done for the following CEC messages:
- <Standby>
- <Image View On> and <Text View On>
- <Give Device Power Status>
- <Set System Audio Mode>
- <Request Current Latency>
If not set, then userspace is responsible for this, and it will have to
configure the CEC devices for HDMI Input and the HDMI Outputs manually.
``manufacturer_name``
---------------------
A three character manufacturer name that is used in the EDID for the HDMI
Input. If not set, then userspace is reponsible for configuring an EDID.
If set, then the driver will update the EDID automatically based on the
resolutions supported by the connected displays, and it will not be possible
anymore to manually set the EDID for the HDMI Input.
``hpd_never_low``
-----------------
If set, then the Hotplug Detect pin of the HDMI Input will always be high,
even if nothing is connected to the HDMI Outputs. If not set (the default)
then the Hotplug Detect pin of the HDMI input will go low if all the detected
Hotplug Detect pins of the HDMI Outputs are also low.
This option may be changed dynamically.

Drivers might also need to iterate over all entities in a graph that can be
reached only through enabled links starting at a given entity. The media
framework provides a depth-first graph traversal API for that purpose.
.. note::
Graphs with cycles (whether directed or undirected) are **NOT**
supported by the graph traversal API. To prevent infinite loops, the graph
traversal code limits the maximum depth to ``MEDIA_ENTITY_ENUM_MAX_DEPTH``,
currently defined as 16.
Drivers initiate a graph traversal by calling
:c:func:`media_graph_walk_start()`
The graph structure, provided by the caller, is initialized to start graph
traversal at the given entity.
Drivers can then retrieve the next entity by calling
:c:func:`media_graph_walk_next()`
When the graph traversal is complete the function will return ``NULL``.
Graph traversal can be interrupted at any moment. No cleanup function call
is required and the graph structure can be freed normally.
Helper functions can be used to find a link between two given pads, or a pad
connected to another pad through an enabled link

Pipeline traversal
^^^^^^^^^^^^^^^^^^
Once a pipeline has been constructed with :c:func:`media_pipeline_start()`,
drivers can iterate over entities or pads in the pipeline with the
:c:macro:´media_pipeline_for_each_entity` and
:c:macro:´media_pipeline_for_each_pad` macros. Iterating over pads is
straightforward:
.. code-block:: c

struct media_pad *pad;
media_pipeline_for_each_pad(pipe, &iter, pad) {
/* 'pad' will point to each pad in turn */

To iterate over entities, the iterator needs to be initialized and cleaned up
as an additional steps:
.. code-block:: c
media_pipeline_entity_iter iter;
struct media_entity *entity;
int ret;
ret = media_pipeline_entity_iter_init(pipe, &iter);

Configuration parameters
========================
The configuration parameters are passed to the
The configuration of the RkISP1 ISP is performed by userspace by providing
parameters for the ISP to the driver using the :c:type:`v4l2_meta_format`
interface.
There are two methods that allow to configure the ISP, the `fixed parameters`
configuration format and the `extensible parameters` configuration
format.
.. _v4l2-meta-fmt-rk-isp1-params:
Fixed parameters configuration format
=====================================
When using the fixed configuration format, parameters are passed to the
:ref:`rkisp1_params <rkisp1_params>` metadata output video node, using
the :c:type:`v4l2_meta_format` interface. The buffer contains
a single instance of the C structure :c:type:`rkisp1_params_cfg` defined in
``rkisp1-config.h``. So the structure can be obtained from the buffer by:
the `V4L2_META_FMT_RK_ISP1_PARAMS` meta format.
The buffer contains a single instance of the C structure
:c:type:`rkisp1_params_cfg` defined in ``rkisp1-config.h``. So the structure can
be obtained from the buffer by:
.. code-block:: c
struct rkisp1_params_cfg *params = (struct rkisp1_params_cfg*) buffer;
This method supports a subset of the ISP features only, new applications should
use the extensible parameters method.
.. _v4l2-meta-fmt-rk-isp1-ext-params:
Extensible parameters configuration format
==========================================
When using the extensible configuration format, parameters are passed to the
:ref:`rkisp1_params <rkisp1_params>` metadata output video node, using
the `V4L2_META_FMT_RK_ISP1_EXT_PARAMS` meta format.
The buffer contains a single instance of the C structure
:c:type:`rkisp1_ext_params_cfg` defined in ``rkisp1-config.h``. The
:c:type:`rkisp1_ext_params_cfg` structure is designed to allow userspace to
populate the data buffer with only the configuration data for the ISP blocks it
intends to configure. The extensible parameters format design allows developers
to define new block types to support new configuration parameters, and defines a
versioning scheme so that it can be extended and versioned without breaking
compatibility with existing applications.
For these reasons, this configuration method is preferred over the `fixed
parameters` format alternative.

``V4L2_PIX_FMT_NV12_10BE_8L128`` is similar to ``V4L2_PIX_FMT_NV12M_10BE_8L128`` but stores
two planes in one memory.
``V4L2_PIX_FMT_MM21`` store luma pixel in 16x32 tiles, and chroma pixels
in 16x16 tiles. The line stride must be aligned to a multiple of 16 and the
image height must be aligned to a multiple of 32. The number of luma and chroma
tiles are identical, even though the tile size differ. The image is formed of
two non-contiguous planes.
``V4L2_PIX_FMT_MT2110T`` is one of Mediatek packed 10bit YUV 4:2:0 formats.
It is fully packed 10bit 4:2:0 format like NV15 (15 bits per pixel), except
that the lower two bits data is stored in separate partitions. The format is
composed of 16x32 luma tiles, and 16x16 chroma tiles. Each tiles is 640 bytes
long, divided into 8 partitions of 80 bytes. The first 16 bytes of the
partition represent the 2 least significant bits of pixel data. The remaining
64 bytes represent the 8 most significant bits of pixel data.

Filtering out the upper part of each partitions results in a valid
``V4L2_PIX_FMT_MM21`` frame. A partition is a sub-tile of size 16 x 4. The
lower two bits is said to be tiled since each bytes contains the lower two
bits of the column of for pixel matching the same index. The chroma tiles
only have 4 partitions.

- A buffer is allocated either in coherent (it will be automatically
coherent between the CPU and the bus) or non-coherent memory. The
latter can provide performance gains, for instance the CPU cache
sync/flush operations can be avoided if the buffer is accessed by the
corresponding device only and the CPU does not read/write to/from that
buffer. However, this requires extra care from the driver -- it must
guarantee memory consistency by issuing a cache flush/sync when
consistency is needed. If this flag is set V4L2 will attempt to
allocate the buffer in non-coherent memory. The flag takes effect
only if the buffer is used for :ref:`memory mapping <mmap>` I/O and the
queue reports the :ref:`V4L2_BUF_CAP_SUPPORTS_MMAP_CACHE_HINTS
<V4L2-BUF-CAP-SUPPORTS-MMAP-CACHE-HINTS>` capability.
