Add support for the multi-planar variants of NV12. The RGA is now able
to exchange DMABUFs with other devices that only support multi-planar
NV12, for example the Hantro JPEG encoder.

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
separate planes.
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,
but the multi-planar API is required for multi-planar formats.

Use the provided V4L2_TYPE_IS_{OUTPUT,CAPTURE} macros to check if the

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.

The RGA DMA descriptor list contains only 32-bit addresses. Set the

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.

Moving the location of the hooks to VFE power domains has several
advantages.
1. Separation of concerns and functional decomposition.
vfe.c should be responsible for and know best how manage
power-domains for a VFE, excising from camss.c follows this
principle.
2. Embedding a pointer to genpd in struct camss_vfe{} meas that we can
dispense with a bunch of kmalloc array inside of camss.c.
3. Splitting up titan top gdsc from vfe/ife gdsc provides a base for
breaking up magic indexes in dtsi.

For the various versions of VFE we have a boiler-plate
pm_domain_on/pm_domain_off callback pair of the general form.
- Error check.
Not always done but applicable to all.
- device_link_add (DL_FLAG_STATELESS | DL_FLAG_PM_RUNTIME |
DL_FLAG_RPM_ACTIVE);
- Error check returning -EINVAL on error.
- Return 0
Reduce the pattern down to a common callback. VFE 4.1 is a special case
which to me also indicates that it is worthwhile maintaining an indirection
for the vfe_pm_domain_{on|off} for now.
Otherwise lets chuck out a bunch of needlessly replicated code.

Right now we use the top-level camss structure to provide pointers via
VFE id index back to genpd linkages.
In effect this hard-codes VFE indexes to power-domain indexes in the
dtsi and mandates a very particular ordering of power domains in the
dtsi, which bears no relationship to a real hardware dependency.
As a first step to rationalising the VFE power-domain code and breaking
the magic indexing in dtsi use per-VFE pointers to genpd linkages.
The top-level index in msm_vfe_subdev_init is still used to attain the
initial so no functional or logical change arises from this change.

At the moment we have some complex code for determining if a VFE requires a
power-domain attachment. Particularly discordant in this scheme is the
subtle reliance on VFE and VFE Lite declaration ordering in our resources.
VFE id is used to determine if a VFE is lite or not and consequently if a
VFE requires power-domain attachment. VFE Lite though is not a correct
delineation between power-domain and non power-domain state since early
SoCs have neither VFE Lite nor power-domains attached to VFEs.
Introduce has_pd to the VFE resource structure to allow the CAMSS code to
understand if it needs to try to attach a power-domain for a given VFE.
As a side-effect from this we no longer need to care about VFE Lite or
non-Lite or the id number associated with either and which order the
VFE/VFE Lite was declared in.
