Subject: [PATCH v9 00/11] Renesas Capture Engine Unit (CEU) V4L2 driver
Hello,
finally I addressed Laurent's comment on ov772x frame rate handling, which
I almost forgot about :)
Also, Sergei reported that the ceu node name should be generic, so I changed it
to "ceu: camera@...10000".
All patches but the trivial [11/11] one are now reviewed/acked. Hope this is
last iteration for CEU!
Series based on top of Hans':
[PATCHv2 0/9] media: replace g/s_parm by g/s_frame_interval
and makes use of newly introduced v4l2_g/s_parm_cap() functions from v4l2-common
in CEU's g/s_parm() callbacks.
A branch for testing is available at:
git://jmondi.org/linux ceu/media-tree-parm/v9
with few patches for Migo-R and GR-Peach applied on top of Hans' media-tree/parm
branch.
------------------------------------------------------------------------------
Copying from v7 cover letter:
The 2 new patches in the series:
[11/11] has been added to silence a v4l2-compliance error, and modifies
ov7670 driver to set all fields of 'struct v4l2_mbus_format' during set_format
operation, including ycbcr_enc, quantization and xfer_func. As the patch commit
reports, this suppresses the following v4l2-compliance error:
fail: v4l2-test-formats.cpp(335): ycbcr_enc >= 0xff
v8/v9: Did the same for ov772x
[7/11] has been required by Hans to add frame interval handling to ov772x
driver. As this is quite a big change I kept it in a separate patch to ease
review, it can eventually be squashed on [6/11] if accepted.
v8: Calculate PLL divider/multiplier in place of using static tables.
v9: Address Laurent's comment on frame rate handling patch
If for TW9910 video decoder the same is required (frame interval handling) I'm
in favour of moving that driver to staging as it was proposed for ov772x before
this series.
------------------------------------------------------------------------------
v4l2-compliance:
v4l2-compliance requires a fix to relax buffer type check on s/g_parm
(see Hans' "[PATCHv2 9/9] vidioc-g-parm.rst: also allow _MPLANE buffer types")
Issue is addressed by patch
"[PATCH] v4l2-compliance: Relax g/s_parm type check"
just sent to linux-media mailing list.
With that fixed, I have v4l2-compliance exhausting my tiny GR-Peach 6MB of
available system, and thus failing when allocating buffers to test "Buffer
IOCTLs":
renesas-ceu e8210000.camera: dma_alloc_coherent of size 307200 failed
Unable to request buffers: Cannot allocate memory (12).
Also, Hans, you asked me to run v4l2-compliance with the -f option, I cannot do
that on my tiny GR-Peach as with its limited available system memory it cannot
allocate the number of requested buffers for that test.
I won't stress here why I cannot do that on Migo-R, long story short: I need a
special compiler with DSP support to run anything but the little
initramfs I have received for SH7722. I've been able to tweak yavta to work and
test capture and frame rate handling with it, but v4l2-compliance is much more
complex and I don't think I'll be able run it on that platform.
I have verified capture still works properly in all supported image formats.
Below v4l2-compliance output, with 2 errors due to memory constraints on my
test platform. Hope this won't cause issues with ceu driver acceptance now
that we're so close to have it finalized :)

Thanks
j
v8->v9:
- Address Laurent's review of ov772x frame rate
- Address Sergei comment on ceu node name
v7->v8:
- Calculate PLL divider/multiplier and do not use static tables
- Change RZ/A1-H to RZ/A1H (same for L) in bindings documentation
- Use rounded clock rate in Migo-R board code as SH clk_set_clk()
implementation does not perform rounding
- Set ycbcr_enc and other fields of v4l2_mbus_format for ov772x as patch
[11/11] does for ov7670
v6->v7:
- Add patch to handle ycbr_enc and other fields of v4l2_mbus_format for ov7670
- Add patch to handle frame interval for ov772x
- Rebased on Hans' media-tree/parm branch with v4l2_g/s_parm_cap
- Drop const modifier in CEU releated fields of Migo-R setup.c board file
to silence complier warnings.
v5->v6:
- Add Hans' Acked-by to most patches
- Fix a bad change in ov772x get_selection
- Add .buf_prepare callack to CEU and verify plane sizes there
- Remove VB2_USERPTR from supported io_modes in CEU driver
- Remove read() fops in CEU driver
v4->v5:
- Added Rob's and Laurent's Reviewed-by tag to DT bindings
- Change CEU driver module license to "GPL v2" to match SPDX identifier as
suggested by Philippe Ombredanne
- Make struct ceu_data static as suggested by Laurent and add his
Reviewed-by to CEU driver.
v3->v4:
- Drop generic fallback compatible string "renesas,ceu"
- Addressed Laurent's comments on [3/9]
- Fix error messages on irq get/request
- Do not leak ceudev if irq_get fails
- Make irq_mask a const field
v2->v3:
- Improved DT bindings removing standard properties (pinctrl- ones and
remote-endpoint) not specific to this driver and improved description of
compatible strings
- Remove ov772x's xlkc_rate property and set clock rate in Migo-R board file
- Made 'xclk' clock private to ov772x driver in Migo-R board file
- Change 'rstb' GPIO active output level and changed ov772x and tw9910 drivers
accordingly as suggested by Fabio
- Minor changes in CEU driver to address Laurent's comments
- Moved Migo-R setup patch to the end of the series to silence 0-day bot
- Renamed tw9910 clock to 'xti' as per video decoder manual
- Changed all SPDX identifiers to GPL-2.0 from previous GPL-2.0+
v1->v2:
- DT
-- Addressed Geert's comments and added clocks for CEU to mstp6 clock source
-- Specified supported generic video iterfaces properties in dt-bindings and
simplified example
- CEU driver
-- Re-worked interrupt handler, interrupt management, reset(*) and capture
start operation
-- Re-worked querycap/enum_input/enum_frameintervals to fix some
v4l2_compliance failures
-- Removed soc_camera legacy operations g/s_mbus_format
-- Update to new notifier implementation
-- Fixed several comments from Hans, Laurent and Sakari
- Migo-R
-- Register clocks and gpios for sensor drivers in Migo-R setup
-- Updated sensors (tw9910 and ov772x) drivers headers and drivers to close
remarks from Hans and Laurent:
--- Removed platform callbacks and handle clocks and gpios from sensor drivers
--- Remove g/s_mbus_config operations
