03d67e706f [media] coda: bump maximum number of internal framebuffers to 17
The h.264 standard allows up to 16 reference frame for the high profile
and we need one additional internal framebuffer when the VDOA is in use.

Lift the current maximum of 8 internal framebuffers to allow playback
of those video streams.

678bc0adf7 [media] coda: remove redundant call to v4l2_m2m_get_vq
The call to v4ls_m2m_get_vq is only used to get the return value
which is not being used, so it appears to be redundant and can
be removed.

89ed025d5c [media] coda: disable BWB for all codecs on CODA 960
I don't know what the BWB unit is, I guess W is for write and one of the
Bs is for burst. All I know is that there repeatedly have been issues
with it hanging on certain streams (ENGR00223231, ENGR00293425), with
various firmware versions, sometimes blocking something related to the
GDI bus or the GDI AXI adapter. There are some error cases that we don't
know how to recover from without a reboot. Apparently this unit can be
disabled by setting bit 12 in the FRAME_MEM_CTRL mailbox register to
zero, so do that to avoid crashes.

Side effects are reduced burst lengths when writing out decoded frames
to memory, so there is an "enable_bwb" module parameter to turn it back
on.

d40e98c13b [media] coda: support YUYV output if VDOA is used
The VDOA is able to transform the NV12 custom macroblock tiled format of
the CODA to YUYV format. If and only if the VDOA is available, the
driver can also provide YUYV support.

While the driver is configured to produce YUYV output, the CODA must be
configured to produce NV12 macroblock tiled frames and the VDOA must
transform the intermediate result into the final YUYV output.

e7f3c54810 [media] coda: use VDOA for un-tiling custom macroblock format
If the CODA driver is configured to produce NV12 output and the VDOA is
available, the VDOA can be used to transform the custom macroblock tiled
format to a raster-ordered format for scanout.

In this case, set the output format of the CODA to the custom macroblock
tiled format, disable the rotator, and use the VDOA to write to the v4l2
buffer. The VDOA is synchronized with the CODA to always un-tile the
frame that the CODA finished in the previous run.

f6e45661f9 dma, mm/pat: Rename dma_*_writecombine() to dma_*_wc()
Rename dma_*_writecombine() to dma_*_wc(), so that the naming
is coherent across the various write-combining APIs. Keep the
old names for compatibility for a while, these can be removed
at a later time. A guard is left to enable backporting of the
rename, and later remove of the old mapping defines seemlessly.

Build tested successfully with allmodconfig.

The following Coccinelle SmPL patch was used for this simple
transformation:

@ rename_dma_alloc_writecombine @
expression dev, size, dma_addr, gfp;
@@

-dma_alloc_writecombine(dev, size, dma_addr, gfp)
+dma_alloc_wc(dev, size, dma_addr, gfp)

@ rename_dma_free_writecombine @
expression dev, size, cpu_addr, dma_addr;
@@

-dma_free_writecombine(dev, size, cpu_addr, dma_addr)
+dma_free_wc(dev, size, cpu_addr, dma_addr)

@ rename_dma_mmap_writecombine @
expression dev, vma, cpu_addr, dma_addr, size;
@@

-dma_mmap_writecombine(dev, vma, cpu_addr, dma_addr, size)
+dma_mmap_wc(dev, vma, cpu_addr, dma_addr, size)

We also keep the old names as compatibility helpers, and
guard against their definition to make backporting easier.

Instead of just checking the first and last bytes for the SOI and EOI

bytes after the EOI marker as hardware generated JPEGs sometimes contain

df9ecb0cad [media] vb2: drop v4l2_format argument from queue_setup
The queue_setup callback has a void pointer that is just for V4L2
and is the pointer to the v4l2_format struct that was passed to
VIDIOC_CREATE_BUFS. The idea was that drivers would use the information
from that struct to buffers suitable for the requested format.

After the vb2 split series this pointer is now a void pointer,
which is ugly, and the reality is that all existing drivers will
effectively just look at the sizeimage field of v4l2_format.

To make this more generic the queue_setup callback is changed:
the void pointer is dropped, instead if the *num_planes argument
is 0, then use the current format size, if it is non-zero, then
it contains the number of requested planes and the sizes array
contains the requested sizes. If either is unsupported, then return
-EINVAL, otherwise use the requested size(s).

of v4l2_plane.

        } m;
        unsigned int            data_offset;

7385817359 genalloc: add name arg to gen_pool_get() and devm_gen_pool_create()
This change modifies gen_pool_get() and devm_gen_pool_create() client
interfaces adding one more argument "name" of a gen_pool object.

Due to implementation gen_pool_get() is capable to retrieve only one
gen_pool associated with a device even if multiple gen_pools are created,
fortunately right at the moment it is sufficient for the clients, hence
provide NULL as a valid argument on both producer devm_gen_pool_create()
and consumer gen_pool_get() sides.

Because only one created gen_pool per device is addressable, explicitly
add a restriction to devm_gen_pool_create() to create only one gen_pool
per device, this implies two possible error codes returned by the
function, account it on client side (only misc/sram).  This completes
client side changes related to genalloc updates.

a269e53b1a [media] coda: add macroblock tiling support
Storing internal frames in macroblock tiled order improves memory
access patterns by allowing increased burst sizes when transferring
the uncompressed macroblocks to or from main memory.
The translation logic only supports a single chroma base address,
so this is only supported for the chroma interleaved NV12 format.

Since the rotator used to copy the decoder output into the v4l2
capture buffers does not seem to support the tiled format correctly,
only enable it in the encoder for now.
