Add support for MFCv12, with a new register file and necessary hw
control, decoder, encoder and structural changes. Add luma dbp, chroma
dpb and mv sizes for each codec as per the UM for MFCv12, along with
appropriate alignment.

Renames macro IS_MFCV10 to IS_MFCV10_PLUS so that the MFCv10 code can
be resued for MFCv12 support. Since some part of MFCv10 specific code
holds good for MFCv12 also.

The use of \n as a line ending throughout the driver is inconsistent.
While it is possible for logging messages to automatically have newlines
added by the kernel printk mechanisms, this is specifically to support
continued lines with PR_CONT and the lack of a new line character
indicates that the text is a fragment of a continuation line.
As each of these lines are whole and not fragments, explicitly define the
newline for consistency.

The only known devices that use an ov2740 sensor in combination with
the ipu-bridge code are various Lenovo ThinkPad models, which all
need the link-frequency to be 180 MHz for things to work properly.
The ov2740 driver used to only support 360 MHz link-frequency,
which is why the ipu-bridge entry used 360 MHz, but now the
ov2740 driver has been extended to also support 180 MHz.
The ov2740 is actually used with 360 MHz link-frequency on Chromebooks.
On Chromebooks the camera/sensor fwnode graph is part of the ACPI tables.
The ipu-bridge code is used to dynamically generate the graph when it is
missing, so it is not used on Chromebooks and the ov2740 will keep using
360 MHz link-frequency there as before.

On various Lenovo Thinkpad models with an ov2740 sensor the 360 MHz
link frequency is not supported.
Add support for 180 MHz link frequency, even though this has half the
pixel clock, this supports the same framerate by using half the VTS value
(significantly reducing the amount of empty lines send during vblank).
Normally if there are multiple link-frequencies then the sensor driver
choses the lowest link-frequency still usable for the chosen resolution.
In this case the board supports only 1 link-frequency. Which frequency
is supported is checked in ov2740_check_hwcfg() and then a different
set of supported_modes (using only the supported link-freq) is selected.
The register settings for this were taken from the ov2740 sensor driver
in the out of tree IPU6 driver:

HTS must be more then width, so the 1080 value clearly is wrong,
this is then corrected with some weird math dividing clocks in
to_pixels_per_line() which results in the hts getting multiplied by 2,
resulting in 2160.
Instead just directly set hts to the correct value of 2160 and
drop to_pixels_per_line().

change the power-state (_PS0 and _PS3) fully take care of powering
on/off the sensor.
On other ACPI platforms, such as e.g. various ThinkPad models with

and the sensor's clock itself.

As a result of converting to the stream-aware state functions, commit
bc0e8d91feec ("media: v4l: subdev: Switch to stream-aware state
functions") caused the sd pointer of the state passed to the
v4l2_subdev_state_get_crop() function to be dereferenced. It however
missed that the atmel-isi driver creates the v4l2_subdev_state instance
on the stack (which it shouldn't do, but that's a separate problem),
without initializing the sd field. This results in a null pointer
dereference.
Fix it by initializing the sd field.

Not all SC7280 devices ship with ChromeOS firmware. Other devices need
PAS for image authentication. That requires the predefined virtual
address ranges to be passed via scm calls. Define them to enable Venus
on non-CrOS SC7280 devices.

Supported media bus codes on the resizer sink pad are identical to the
ISP source pad. The .enum_mbus_code() handler thus delegates the
enumeration to the ISP's operation. This is problematic for two
reasons:
- Format enumeration on the ISP source pad is dependent on the format
configured on the ISP sink pad for the same subdev state (TRY or
ACTIVE), while format enumeration on the resizer sink pad should
return all formats supported by the resizer subdev, regardless of the
ISP configuration.
- Delegating the operation involves creating a fake v4l2_subdev_state on
the stack to pass to the ISP .enum_mbus_code() handler. This gets in
the way of evolution of both the ISP enumeration handler and, more
generally, the V4L2 subdev state infrastructure.
Fix those two issues by implementing format enumeration manually for the
resizer.

In rkisp1_isp_stop() and rkisp1_csi_disable() the driver masks the
interrupts and then apparently assumes that the interrupt handler won't
be running, and proceeds in the stop procedure. This is not the case, as
the interrupt handler can already be running, which would lead to the
ISP being disabled while the interrupt handler handling a captured
frame.
This brings up two issues: 1) the ISP could be powered off while the
interrupt handler is still running and accessing registers, leading to
board lockup, and 2) the interrupt handler code and the code that
disables the streaming might do things that conflict.
It is not clear to me if 2) causes a real issue, but 1) can be seen with
a suitable delay (or printk in my case) in the interrupt handler,
leading to board lockup.

The IRQ handler rkisp1_isr() calls sub-handlers, all of which returns an
irqreturn_t value, but rkisp1_isr() ignores those values and always
returns IRQ_HANDLED.
Fix this by collecting the return values, and returning IRQ_HANDLED or
IRQ_NONE as appropriate.

In all known platforms the ISP has dedicated IRQ lines, but for some
reason the driver uses IRQF_SHARED.
Supporting IRQF_SHARED properly requires handling interrupts even when
our device is disabled, and the driver does not handle this. To avoid
adding such code, and to be sure the driver won't accidentally be used
in a platform with shared interrupts, let's drop the IRQF_SHARED flag.
