Make sure to check that we have at least one endpoint before accessing
the endpoint array to avoid dereferencing a NULL-pointer on stream
start.
Note that these sanity checks are not redundant as the driver is mixing
looking up altsettings by index and by number, which need not coincide.

From the measured hardware signal, OV5695 reset pin goes high for a
short period of time during boot-up. From the sensor specification, the
reset pin is active low and the DT binding defines the pin as active
low, which means that the values set by the driver are inverted and thus
the value requested in probe ends up high.
Fix it by changing probe to request the reset GPIO initialized to high,
which makes the initial state of the physical signal low.
In addition, DOVDD rising must occur before DVDD rising from spec., but
regulator_bulk_enable() API enables all the regulators asynchronously.
Use an explicit loops of regulator_enable() instead.
For power off sequence, it is required that DVDD falls first. Given the
bulk API does not give any guarantee about the order of regulators,
change the driver to use regulator_disable() instead.
The sensor also requires a delay between reset high and first I2C
transaction, which was assumed to be 8192 XVCLK cycles, but 1ms is
recommended by the vendor. Fix this as well.

When supporting Rpi Camera v2 Module on the RZ/G2E, found the driver had
some issues with rcar mipi-csi driver. The sensor never entered into LP-11
state.
The powerup sequence in the datasheet[1] shows the sensor entering into
LP-11 in streaming mode, so to fix this issue transitions are performed
from "streaming -> standby" in the probe() after power up.
With this commit the sensor is able to enter LP-11 mode during power up,
as expected by some CSI-2 controllers.

The debug output for tvp5150_selmux() isn't really intuitive. Register
values are printed decimal formatted and the input/output driver states
are printed as enum. Even more the "normal" output enum mapps to zero so

The tvp5150 accepts NTSC(M,J,4.43), PAL (B,D,G,H,I,M,N) and SECAM video
data and is able to auto-detect the input signal. The auto-detection
does not work if the connector does not receive an input signal and the
tvp5150 might not be configured correctly. This misconfiguration leads
into wrong decoded video streams if the tvp5150 gets powered on before
the video signal is present.

connector to avoid a misconfiguration.

This patch adds the of_graph support to describe the tvp input connections.
Physical the TVP5150 has three ports: AIP1A, AIP1B and YOUT. As result
of discussion [1],[2] the device-tree maps these ports 1:1. Look at the
Documentation for more information. Since the TVP5150 is a converter/bridge
the device-tree must contain at least 1-input and 1-output port. The
mc-connectors and mc-links are only created if the device-tree contains the
corresponding connector nodes. If more than one connector is available the
media_entity_operations.link_setup() callback ensures that only one
connector is active.

Commit f7b4b54e6364 ("[media] tvp5150: add HW input connectors support")
added input signals support for the tvp5150, but the approach was found
to be incorrect so the corresponding DT binding commit 82c2ffeb217a
("[media] tvp5150: document input connectors DT bindings") was reverted.
This left the driver with an undocumented (and wrong) DT parsing logic,
so lets get rid of this code as well until the input connectors support
is implemented properly.
It's a partial revert due other patches added on top of mentioned commit
not allowing the commit to be reverted cleanly anymore. But all the code
related to the DT parsing logic and input entities creation are removed.

Currently every driver needs to parse the connector endpoints by it self.
This is the initial work to make this generic. A generic connector has
common members and connector specific members. The common members are:
- type
- label (optional)
- links
- nr_of_links
The specific members are stored within a union, since only one of them
can be available at the time. Since this is the initial support the
patch adds only the analog-connector specific ones.

Some connectors no matter if in- or output supports only a limited
range of sdtv standards. It doesn't matter if the hardware behind that
connector supports more than the listed formats since the users are
restriced by a label e.g. to plug only a camera into this connector
which uses the PAL format.
This patch adds the capability to describe such limitation within the
firmware. There are no format restrictions if the property isn't
present, so it's completely backward compatible.

After the switch to use v4l2_async_notifier_add_subdev() and
v4l2_async_notifier_cleanup(), unloading the ti_cal module would cause a
kernel oops.
This was root cause to the fact that v4l2_async_notifier_cleanup() tries
to kfree the asd pointer passed into v4l2_async_notifier_add_subdev().
In our case the asd reference was from a statically allocated struct.
So in effect v4l2_async_notifier_cleanup() was trying to free a pointer
that was not kalloc.
So here we switch to using a kzalloc struct instead of a static one.
To achieve this we re-order some of the calls to prevent asd allocation
from leaking.
