From: Bingbu Cao <bingbu.cao@intel.com>

This is a camera sensor using the I2C bus for control and the
CSI-2 bus for data.

Hi Bingbu,
I love your patch! Perhaps something to improve:
[auto build test WARNING on linuxtv-media/master]
[also build test WARNING on v4.17-rc5 next-20180517]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]
url: https://github.com/0day-ci/linux/commits/bingbu-cao-intel-com/media-imx319-Add-imx319-camera-sensor-driver/20180519-213616
base: git://linuxtv.org/media_tree.git master
reproduce:
# apt-get install sparse
make ARCH=x86_64 allmodconfig
make C=1 CF=-D__CHECK_ENDIAN__
sparse warnings: (new ones prefixed by >>)
>> drivers/media/i2c/imx319.c:219:24: sparse: symbol 'imx319_global_setting' was not declared. Should it be static?
Please review and possibly fold the followup patch.

DW9807 is a 10 bit DAC from Dongwoon, designed for linear
control of voice coil motor.
This driver creates a V4L2 subdevice and
provides control to set the desired focus.

Hi Bingbu,
I love your patch! Perhaps something to improve:
[auto build test WARNING on next-20180517]
[also build test WARNING on v4.17-rc6]
[cannot apply to linuxtv-media/master linus/master v4.17-rc6 v4.17-rc5 v4.17-rc4]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

Add a V4L2 sub-device driver for the Sony IMX319 image sensor.
This is a camera sensor using the I2C bus for control and the
CSI-2 bus for data.

Hello Bingbu,
thanks for the patch

Could you please provide a changelog between versions? Also, I know
using the --in-reply-to option is tempting to keep all patch version
in a single thread, but most people finds it confusing and I rarely
see that.

This hunk does not apply nor on media tree master nor on Linus'
master. Could you please mention on which branch the patch is meant to
be applied in the cover letter? Maybe it's obvious for most people here,
but I failed to find it.

I don't have any major comment actually, this is pretty good for a
first submission.
This worries me a bit though. The media bus format depends on the
V/HFLIP value, I assume this is an hardware limitation. But if
changing the flip changes the reported media bus format, you could
trigger a -EPIPE error during pipeline format validation between two
streaming sessions with different flip settings. Isn't this a bit
dangerous?
Below some minor comments.

I assume powering is handled through ACPI somehow, I know nothing
about that, but I wonder why setting controls should be enabled only
when streaming. I would have expected runtime_pm_get/put in subdevices
node open/close functions not only when streaming. Am I missing something?

This assumes a fixed link frequency and a fixed number of data lanes,
and a fixed bpp value (but this is ok, as all the formats you have are
10bpp). In OF world those parameters come from DT, what about ACPI?

In this function seems like you lost alignment and are breaking lines
when not necessary. Could you please have a look?
Seems like apart a few questions, I only have minor comments then...
Thanks

It is based on sakari media_tree branch.
<URL:https://git.linuxtv.org/sailus/media_tree.git/log/?h=for-4.18-3.1>
I will rebase that in follow patches.

Yes, it is a hardware limitation. Make the sensor support different
bayer order by changing the flip.
Thanks for your point, I will have a deep look for this.

IMO, the device is turned on by i2c-core with binding pm domain, the
logic is runtime power up the subdev
iff enable streaming, thus the v4l2 control only apply and take effect
when the subdev is power-on.

That's how it works on raw bayer sensors; you do have to configure the
entire pipeline accordingly.
What it also means is that the two controls may not be changed during
streaming --- this needs to be prevented by the driver, and I think it's
missing at the moment.

The initial try format should reflect the default, not the current

Power management takes place though ACPI, indeed "somehow" is a good
description of it from a driver developer's point of view. :-) The drivers
simply use runtime PM to invoke it.

You can do it either way. If powering on the sensor takes a long time, then
doing that in the open callback may be helpful as the user space has a way
to keep the device powered.

I presume the driver only supports a particular number of lanes (4). ACPI
supports _DSD properties, i.e. the same can be done on ACPI.
If the driver only supports these, then it should check this matches with
what the firmware (ACPI) has. The fwnode API is the same.

Thanks for explaining. At least my comment lead to something, as my
understanding is that VFLIP and HFLIP should be forbidden when
the sensor is streaming

Ok, so I assume my comment could be ignored, assuming is fine not
being able to set control if the sensor is not streaming. Is it?

Thanks, so I assume those parameters represented in ACPI DSD nodes
will be checked to be supported by the sensor in v2.

I'd say so. From the user's point of view, the sensor doesn't really do
anything when it's in software standby mode.

Just to make sure we're on the same page, the code actually does nothing
when the sensor is not in streaming mode (i.e. powered off). When stream is
being started, the V4L2 control framework will call s_ctrl for all the
controls in the handler to synchronize hardware state and this is when all
the controls set before powering on will actually be programmed into the
hardware registers.
Best regards,
Tomasz

Thanks, I had missed that part.
I quickly tried searching for 's_ctrl' calls in the v4l2-core/ code
and I've found nothing that invokes that in response to a streaming
start operation. Just if you happen to have any reference handy, could
you please point me to that part, just for my better understanding?
Thanks
