If an error occurs after a successful iommu_paging_domain_alloc() call, it
should be undone by a corresponding iommu_domain_free() call, as already
done in the remove function.
In order to fix the issue, move the corresponding call at the end of the

There apparently is no reason to require 3 queued buffers to call
streamon() for the RkISP1 as the driver operates with a scratch buffer
where frames can be directed to if there's no available buffer provided
by userspace.
Reduce the number of required buffers to 1 to allow applications to
operate with a single queued buffer.
Tested with libcamera, by operating with a single capture request. The
same request (and associated capture buffer) gets recycled once
completed. This of course causes a frame rate drop but doesn't hinder
operations.

The rkisp1-params driver assumes the data buffer format is the only

initializing the vb2 queue.
In order to prepare to support the "extensible" format beside the
existing "fixed" one, add support in the driver for both formats by
caching a pointer to the active one in the driver structure and use it
in the vb2 queue operations and subdev pad operations implementations.
Do not yet allow userspace to select between the two formats as the
support for the "extensible" format parsing will be introduced in a later
patch in the series.

The ISP parameters buffers are queued by userspace to the params video
device and appended by the driver to the list of available buffers for
later consumption.
As the parameters buffer is mapped in the userspace process memory,
applications have access to the buffer content after the buffer has
been queued.
To prevent userspace from modifying the contents of the parameters buffer
after it has been queued to the video device, add to 'struct
rkisp1_params_buffer' a scratch buffer where to copy the parameters.
Allocate the scratch buffer in the vb2 buf_init() operation and copy the
buffer content in the buf_prepare() operation. Free the scratch
buffer in the newly introduced buf_cleanup() operation handler.

The i.MX8MP has extra register fields in the memory interface control
register for setting the output format, which work with the output
alignment format register for byte-swapping and LSB/MSB alignment.
With processed and 8-bit raw streams, it doesn't cause any problems to
not set these, but with raw streams of higher bit depth the endianness
is swapped and the data is not aligned properly.
Add support for setting these registers and plumb them in to fix this.

Some versions of the ISP supported by the rkisp1 driver, such as the ISP
in the i.MX8MP, lack the dual crop registers and don't support cropping
at the resizer input. They instead rely on cropping in the Image
Stabilization module, at the output of the ISP, to modify the resizer
input size and implement digital zoom.
Add a dual crop feature flag to distinguish the versions of the ISP that
support dual crop from those that don't, and make sure that the sink
crop is set to the sink format when dual crop is not supported.

The driver requests the interrupts as IRQF_SHARED, so the interrupt
handlers can be called at any time. If such a call happens while the ISP
is powered down, the SoC will hang as the driver tries to access the
ISP registers.
This can be reproduced even without the platform sharing the IRQ line:
Enable CONFIG_DEBUG_SHIRQ and unload the driver, and the board will
hang.
Fix this by adding a new field, 'irqs_enabled', which is used to bail
out from the interrupt handler when the ISP is not operational.

This reverts commit 85d2a31fe4.
The rkisp1 does share interrupt lines on some platforms, after all. Thus
we need to revert this, and implement a fix for the rkisp1 shared irq
handling in a follow-up patch.

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.
