This patch introduces new module parameter, dev, which takes a string
representing the device that the external synth is connected to, e.g.
ttyS0, ttyUSB0 etc. This is then used to communicate with the synth.
That way, speakup can support more than ttyS*. As of this patch, it
only supports ttyS*, ttyUSB* and selected synths for lp*. dev parameter
is only available for tty-migrated synths.
Users will either use dev or ser as both serve same purpose. This patch
maintains backward compatility by allowing ser to be specified. When
both are specified, whichever is non-default, i.e. not ttyS0, is used.
If both are non-default then dev is used.

This patch adds functionality to validate and convert either a device
name or 'ser' memmber of synth into dev_t. Subsequent patch in this set
will call it to convert user-specified device into device number. For
device name, this patch does some basic sanity checks on the string
passed in. It currently supports ttyS*, ttyUSB* and, for selected
synths, lp*.
The patch also introduces a string member variable named 'dev_name' to
struct spk_synth. 'dev_name' represents the device name - ttyUSB0 etc -
which needs conversion to dev_t.

synths[] array caches currently loaded synths. synth_add checks
synths[] before adding a new one. It however ignores the result of
do_synth_init. So when do_synth_init fails, the failed synth is still
cached. Since, as a result module loading fails too, synth_remove -
which is responsible for removing the cached synth - is never called.
Next time the failing synth is added again it succeeds because
synth_add finds it cached inside synths[].
This patch fixes this by caching a synth only after do_synth_init
succeeds.

The original ccree driver was registering a useless setkey
method even for non-MAC hash transformations. Somewhere
around v4.9 a check was added that failed hash operations
if a setkey method was registered but was not called,
so during the initial upstream port code was added to
only register the setkey method for MAC type hash transform.
Unfortunately, the ccree driver also registers non-hash based
MAC transforms and the code had a logic error that stopped
it registering a setkey callback even for those, thus rendering
them useless.
This commit fixes the logic mistake, thus correctly registering
a setkey method only for MAC transformations, leaving it out
for non-MAC ones, whether they are hash based on not.

Add frame size and frame interval enumeration to CSI.
CSI can downscale the image independently horizontally and vertically by a
factor of two, which enumerates to four different frame sizes at the
output pads. The input pad supports a range of frame sizes.
CSI can also drop frames, resulting in frame rate reduction, so
enumerate the resulting possible output frame rates.

Move the crop rectangle to the sink pad and add a sink compose rectangle
to configure scaling. Also propagate rectangles from sink pad to crop
rectangle, to compose rectangle, and to the source pads both in ACTIVE
and TRY variants of set_fmt/selection, and initialize the default crop
and compose rectangles.

Bayer formats must be treated as generic data and passthrough mode must
be used. Add the correct setup for these formats.
- added check to csi_link_validate() to verify that destination is
IDMAC output pad when passthrough conditions exist: bayer formats
and 16-bit parallel buses.

Adds MIPI CSI-2 Receiver subdev driver. This subdev is required
for sensors with a MIPI CSI2 interface.
- Switch from the v4l2_of_ APIs to the v4l2_fwnode_ APIs.
- Add the function csi2ipu_gasket_init() to initialize the gasket at
s_power(ON). The gasket needs to be programmed with the correct color
component ordering to handle UYVY vs. YUYV ordered mbus formats from
sensors. Note that the description of the CSI2IPU_GASKET register in
the i.MX6 reference manual is wrong w.r.t bit 2 (the manual refers to
this register as CSI2_SW_RST): setting bit 2 selects YUYV order, not UYVY.

This is a set of three media entity subdevice drivers for the i.MX
Image Converter:
- Pre-process Router: Takes input frames from CSI0, CSI1, or VDIC.
Two output pads enable either or both of the preprocess tasks
below. If the input is from one of the CSIs, both proprocess task
links can be enabled to process frames from that CSI simultaneously.
If the input is the VDIC, only the Pre-processing Viewfinder task
link can be enabled.
- Pre-processing Encode task: video frames are routed directly from
the CSI and can be scaled, color-space converted, and rotated.
Scaled output is limited to 1024x1024 resolution. Output frames
are routed to the prpenc capture device.
- Pre-processing Viewfinder task: this task can perform the same
conversions as the pre-process encode task, but in addition can
be used for hardware motion compensated deinterlacing. Frames can
come either directly from the CSI or from the VDIC. Scaled output
is limited to 1024x1024 resolution. Output frames are routed to
the prpvf capture device.

This is a media entity subdevice driver for the i.MX Video De-Interlacing
or Combining Block. So far this entity does not implement the Combining
function but only motion compensated deinterlacing. Video frames are
received from the CSI and are routed to the IC PRPVF entity.

- Added support for negotiation of frame intervals.
- Fixed cropping rectangle negotiation at input and output pads.
- Added support for /2 downscaling, if the output pad dimension(s)
are 1/2 the crop dimension(s) at csi_setup() time.

This is the capture device interface driver that provides the v4l2
user interface. Frames can be received from various sources:
- directly from CSI for capturing unconverted images directly from
camera sensors.
- from the IC pre-process encode task.
- from the IC pre-process viewfinder task.
