+description: |
+ The E5010 is a JPEG encoder from Imagination Technologies implemented on
+ TI's AM62A SoC. It is capable of real time encoding of YUV420 and YUV422
+ inputs to JPEG and M-JPEG. It supports baseline JPEG Encoding up to
+ 8Kx8K resolution.

This adds support for stateful V4L2 M2M based driver
for Imagination E5010 JPEG Encoder [1] which supports baseline
encoding with two different quantization tables and compression
ratio as demanded.
Support for both contiguous and non-contiguous YUV420 and YUV422
semiplanar formats is added along with alignment restrictions
as required by the hardware.
System and runtime PM hooks are added in the driver along with v4l2
crop and selection API support.
Minimum resolution supported is 64x64 and
Maximum resolution supported is 8192x8192.
All v4l2-compliance tests are passing [2] :
v4l2-compliance -s -f -a -d /dev/video0 -e /dev/video1
Total for e5010 device /dev/video0: 70, Succeeded: 70, Failed: 0,
Warnings: 0
NOTE: video1 here is VIVID test pattern generator
Also tests [3] were run manually to verify below driver features:
- Runtime Power Management
- Multi-instance JPEG Encoding
- DMABUF import, export support
- NV12, NV21, NV16, NV61 video format support
- Compression quality S_CTRL
Existing V4L2 M2M based JPEG drivers namely s5p-jpeg,
imx-jpeg and rcar_jpu were referred while making this.
TODO:
Add MMU and memory tiling support

This adds node for E5010 JPEG Encoder node which is a stateful
JPEG Encoder supporting baseline encoding for semiplanar YUV420
and YUV422 video formats to JPEG with resolutions supported
from 64x64 up to 8kx8k resolution.
E5010 JPEG Encoder IP is present main domain, so this
also adds address range for core and mmu regions of E5010 IP
in cbass_main node.

I do not see improvements in the subject.

TI did not make e5010. Use SoC-based compatible.

img,e5010-jpeg-enc cannot be compatible with img,e5010-jpeg-enc. It does
not make sense. I guess I did not expect you are going to use what you
wrote in v1 directly... I thought it is just about syntax.

Drop _clk or even drop clock-names. It brings little benefit for
one-entry list.

Sorry but I did not understand this fully, the possible compatibles are:
1) "ti,am62a-jpeg-enc", "img,e5010-jpeg-enc"
or
2) "img,e5010-jpeg-enc"
anything else will not comply during dtbs_check as shown below :
For e.g. If I use below compatible :
"img,e5010-jpeg-enc", "img,e5010-jpeg-enc"
and run dtbs_check, it throw below error :
make CHECK_DTBS=y DT_SCHEMA_FILES=media/img,e5010-jpeg-enc.yaml
ti/k3-am62a7-sk.dtb
LINT Documentation/devicetree/bindings
CHKDT Documentation/devicetree/bindings/processed-schema.json
SCHEMA Documentation/devicetree/bindings/processed-schema.json
DTC_CHK arch/arm64/boot/dts/ti/k3-am62a7-sk.dtb

be fixed:

'ti,am62a-jpeg-enc' was expected
From schema:
/home/devarsht/ti/linux-next2/linux-next/Documentation/devicetree/bindings/media/img,e5010-jpeg-enc.yaml
Similarly, if I use below compatible :
"ti,am62a-jpeg-enc",
It throw below error :
make CHECK_DTBS=y DT_SCHEMA_FILES=media/img,e5010-jpeg-enc.yaml
ti/k3-am62a7-sk.dtb
DTC_CHK arch/arm64/boot/dts/ti/k3-am62a7-sk.dtb

be fixed:

'img,e5010-jpeg-enc' was expected
From schema:
/home/devarsht/ti/linux-next2/linux-next/Documentation/devicetree/bindings/media/img,e5010-jpeg-enc.yaml
But If I use either 1) or 2) it does not throw any error.
Please let me know if I missed to understand your point.

Yes I think it should be possible to have a jpeg helpers library or a common
file for preparing jpeg headers and I am open to look into it but would prefer
to track that as a separate patch and not in this series as I want to spend
some time to design it properly.
For now, I was thinking if I can move all these byte arrays too to
include/media/jpeg.h and update it in V4 and then as a separate patch series
introduce the jpeg encoder helper module which export API to prepare JPEG helpers.
Kindly let me know your opinion.

It's the size of both chroma and luma qp_tables, maybe I can have a macro
QP_TABLE_SIZE instead of using magic numbers.

You can just do:

This can just be:
return reg & JASPER_INTERRUPT_STATUS_CR_PICTURE_DONE_IRQ_MASK;

Just use return write_reg_field_not_busy(), same in the similar instances below.

I haven't read through the whole patch yet, but almost certainly get_queue is
only ever called with V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE or V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE.
So just simplify this:
if (type == V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE)
return &ctx->out_queue;
return &ctx->cap_queue;
Then the caller doesn't need to do any error checking, thus simplifying
the code further.

bus_info is filled in automatically for platform devices, just drop this.

No need for these two lines, the v4l2 framework will use device_caps in struct video_device
to fill this in automatically.

Hmm, this looks very much like the VIDIOC_TRY_FMT is actually updating
real values, instead of just 'trying' them.
I think this belongs in s_fmt below. Same for the other changes to
queue in this function.

No need for this, done by the v4l2 framework.

And here is where the actualy updates to e5010_q_data should take place, I think.
It certainly does not make sense that s_fmt is just the same as try_fmt. That
can really only happen if there is just a single hardcoded format, and that isn't
the case here.

This must be done last. As soon as you register the video device it can be
used, so registering the video device should only be done once everything
else is set up correctly.
