Change compatible string to match dt bindings for TI devices. K3 family
prefix should not be included as it deviates from naming convention.

Add allocation of DPB buffers based on MFC requirement so,
codec buffers allocations has been moved after state
MFCINST_HEAD_PRODUCED. It is taken care that codec buffer allocation
is performed in process context from userspace IOCTL call.

Context bit is set for hardware execution if there is a buffer in
source and destination queue before calling try_run in the
init_buffers function. Now there will be a new context created and
hardware will be invoked for the buffer queued instead of waiting for
another buffer to be queued from userspace to set this context bit for
hw execution.

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.

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.

The extended address registers are missing in the debug output register
list. These are only available on 36-Bit DMA platforms. Due to the
prolonged name, the output width has to be adjusted as well.

The driver always enables the clocks at probe() and disables them only
at remove(). It is not clear why the driver does this, as it supports
runtime PM, and enables and disables the clocks in the runtime resume
and suspend callbacks. Also, in the case runtime PM is not available,
the driver calls the resume and suspend callbacks manually from probe()
and remove().
Drop the unnecessary clock enable, thus enabling the clocks only when
actually needed.

The driver always calls mipi_csis_runtime_suspend() and
mipi_csis_clk_disable() in remove(). This causes multiple WARNs from the
kernel, as the clocks get disabled too many times.
Fix the remove() to call mipi_csis_runtime_suspend() and
mipi_csis_clk_disable() in a way that reverses what is done in probe().

Multi-planar formats may have multiple planes that must be handled and
correctly mapped into a continuous buffer for the RGA by using the DMA
descriptors.
The plane offsets in the continuous mapping may now start at page
boundaries and the previous calculation based on the frame sizes is only
valid for planar buffers in a single memory. Therefore, the offsets must
be detected and set while creating the mapping.

Switch to the multi-planar API, which allows to handle buffers with

The RGA driver doesn't expose multi-planar formats, yet. The existing
contiguous planar formats can be used with the multi-planar API as well,

Use the pixelformat instead of the v4l2_format to find the rga_fmt. This
avoids knowing the structure and type of v4l2_format in rga_fmt_find and
simplifies the function.
Also cleanup the users of the function. In try_fmt always return the
found pixel format to make sure that the pixel format is always set.
Thus, we can be sure that we will find the rga_fmt in s_fmt and can drop
the check if a given format has been found.

Calculate the plane offsets and store them with the video buffer while
creating the buffer mapping.
This allows the driver to more freely handle the memory of the DMA
mapping as the offsets and the mapping can be kept in sync.
The driver still has to update the offsets to respect the configured
cropping and rotation, but this calculation is now separated from the
calculation of the plane offsets.

The RGA driver allocates two buffers for the DMA descriptors of the
input and output buffers. Whenever a new job is processed, the
descriptor list is updated for the current buffers.
By updating the descriptor list during buf_prepare, it is possible to
correctly fail DMABUF imports if the buffers that shall be imported are
not within the 32 bit address range that can be addressed by the RGA.
Managing the DMA descriptor list with the buffer also makes it easier to
track the buffer mapping and the plane offsets into this mapping.
The cost is that the driver now requires DMA coherent memory per buffer
for the descriptor list. However, the size scales with the size of the
video buffers and is not allocated if the RGA is not used.
While at it, use dma_alloc_coherent to allocate the descriptors and get
rid of the virt_to_phys calls to get the physical addresses.

The IOMMU of the RGA is programmed with a list of DMA descriptors that
contain an 32 bit address per 4k page in the video buffers. The address
in the descriptor points to the start address of the page.
Introduce 'struct rga_dma_desc' to make the handling of the DMA
descriptors explicit instead of hiding them behind standard types.
While at it, use provided helpers for iterating the sg_table instead of
manually calculating the DMA addresses.

When using 32 bit RGB formats, the RGA on the rk3568 produces wrong
colors as the wrong color channels are read or written. The reason is
that the format description for the channel swizzeling is wrong and the
wrong bits are configured. For example, when converting ARGB32 to NV12,
the alpha channel is used as blue channel.. This doesn't happen if the
color format is the same on both sides.
Fix the color_swap settings of the formats to correctly handle 32 bit
RGB formats.
For RGA_COLOR_FMT_XBGR8888, the RGA_COLOR_ALPHA_SWAP bit doesn't have an
effect. Thus, it isn't possible to handle the V4L2_PIX_FMT_XRGB32. Thus,
it is removed from the list of supported formats.

Right now we use fixed indexes to assign power-domains, with a
requirement for the TOP GDSC to come last in the list.
Adding support for named power-domains means the declaration in the dtsi
can come in any order.
After this change we continue to support the old indexing - if a SoC
resource declaration or the in-use dtb doesn't declare power-domain names
we fall back to the default legacy indexing.
From this point on though new SoC additions should contain named
power-domains, eventually we will drop support for legacy indexing.
