Santiago,

Thanks for sending the patch for review.

I was surprised to see the hw configuration part of the code is different from LSP 2.10. Having a entirely new code adds to the risk in development.
Any reason, why you have chosen not to re-use the code?

Here are the additional comments I have on the patch..

- So many controls added. So what are your requirement w.r.t to control from user space? Whatever controls used should be standard ones picked from the v4l2 spec or that we could add to v4l2 spec. Many of the controls that you have implemented should be left as defaults or should be exported to user space as a configuration ioctl if require configuration from user space. Only control that make sense to me is the analog and digital gain/offsets and clamp. Also these controls may not be available for all types of input. For example since chip support capture from a vesa source, it may be supporting gain/offsets in RGB color space, but for TV input, the data is in YPbPr color space. Please investigate this. Also check videodev2.h in latest open source kernel to investigate if there are control ids available to implement these or need to add new ones.

- So many modes available. But only 2 are added to vpfe capture. What are the requirements here? If you need VESA timings and video (Analog & Digital) timings, then it make sense to support all modes that are supported by the chip. In that case you need to add the timing for this in the vpfe capture driver as well. Also input selection from all these sources should be possible. But at least from DM365 and DM6467 perspectives, I would like to see support for 720p 50/60, 1080i 50/60 & 1080p 50/60 for HDTV and also 480p/576p for SDTV.  Please clarify.

- The comments are using // which are not allowed. Please refer the coding style for open source development.

- Please split this into multiple patches and add description to each. So
  when you are ready to submit it to community, it will be a lot easier.

See additional comments inline below with [MK] prefix.

[MK] I don't see it being used in your driver TVP7002 driver. In probe() these values are to be read and used for setting polarities as needed. This will allow for customization in individual boards. So also add fid polarity and clock polarity which are also configurable in the chip.

[MK]You have used many modes in your driver. Why only these used here. What is V4L2_STD_725_50 & V4L2_STD_825_60? Whatever modes required as per the requirement should be added here so that vpfe capture will be able to support it while doing s_std().

[MK] OUTPUT_10BIT_422_EMBEDDED_SYNC is not correct for TVP7002. It should be
20bit 422. But both of these are not required in my opinion as given below.
This is part of the interface configuration.

[MK]If your requirement is to support multiple input sources:- to capture from PC VESA source, Composite source or component source etc, then it make sense to create multiple input selection logic. In that case multiple inputs to be defined and corresponding selector values are required in tvp7002 routes. If your driver is just supporting component input to capture 480p/576p and HD standards, then you may not require to add routes here and need not set can_route below. I see only requirement to capture from TV source at this time. Is this a requirement from Ridgerun to support VESA ?

[MK] I think you need to Keep 3 set of timings. One for Analog TV standard, like NTSC, PAL as in TVP514x and another for VESA timings, and third for Digital TV timings. That way at least the analog TV standards handling code will not change in future since that is well standardized. Digital video and VESA timings are to be changed using the new IOCTL being proposed by Hans. So if that accepted in some form, only that code needs to be modified.

[MK] See my earlier comment. Only keep Gain/Offset/Clamp for control. Rest of them use default to begin with unless you have specific requirement to support.

[MK] Why can't use i2c_smbus_read_byte_data() as in tvp514x? Why send and receive(). This always create problems when multiple tasks use the driver, when while one send a command, get swapped and another use i2c to send/receive commands. It appears that you have used TVP5150 code as reference. There is a kernel oops discussion relating to tvp5150 in the linux-media list and it is attributed to this , I think.

Murali,


Thanks for promptly reviewing the code. Please see inline comments.

The reason for not reusing the code was based upon the amount of changes 
in the v4l2 interface in TVP7002 between 2.6.18 and 2.6.31, which made 
some changes unnatural with respect to functionality and semantics. I 
also agree this was a risky approach though.

> - So many controls added. So what are your requirement w.r.t to control from user space? Whatever controls used should be standard ones picked from the v4l2 spec or that we could add to v4l2 spec. Many of the controls that you have implemented should be left as defaults or should be exported to user space as a configuration ioctl if require configuration from user space. Only control that make sense to me is the analog and digital gain/offsets and clamp. Also these controls may not be available for all types of input. For example since chip support capture from a vesa source, it may be supporting gain/offsets in RGB color space, but for TV input, the data is in YPbPr color space. Please investigate this. Also check videodev2.h in latest open source kernel to investigate if there are control ids available to implement these or need to add new ones.
>   
I will reduce the amount of controls to standard ones in V4L2 and work 
with the community for the new ones.
> - So many modes available. But only 2 are added to vpfe capture. What are the requirements here? If you need VESA timings and video (Analog & Digital) timings, then it make sense to support all modes that are supported by the chip. In that case you need to add the timing for this in the vpfe capture driver as well. Also input selection from all these sources should be possible. But at least from DM365 and DM6467 perspectives, I would like to see support for 720p 50/60, 1080i 50/60 & 1080p 50/60 for HDTV and also 480p/576p for SDTV.  Please clarify.

>   
For the specific case of modes, the main goal was to match as closely as 
possible the tvp7002 specification on modes it provides but I'd like to 
hear from the expectations of the community on which modes are 
prioritary. I will add specific support for those above mentioned.

Understood. Read relevant open source docs and working on matching the 
standard.

It is required by vpfe_capture for setting up polarities. Will add fid 
and clocl polarity.

I will add the other modes as suggested. In the case of the mode 
definitions, my impression was that there existed a convention since the 
other modes (V4L2_STD_525_60 and V4L2_STD_625_50) provide no immediate 
information upon their names on resolution, only frequency. Should they 
be redefined according to these criteria?

In that case multiple inputs to be defined and corresponding selector values are required in tvp7002 routes. If your driver is just supporting component input to capture 480p/576p and HD standards, then you may not require to add routes here and need not set can_route below. I see only requirement to capture from TV source at this time. Is this a requirement from Ridgerun to support VESA ?

Ok. Changing to support SD/HD standards.

> [MK] I think you need to Keep 3 set of timings. One for Analog TV standard, like NTSC, PAL as in TVP514x and another for VESA timings, and third for Digital TV timings. That way at least the analog TV standards handling code will not change in future since that is well standardized. Digital video and VESA timings are to be changed using the new IOCTL being proposed by Hans. So if that accepted in some form, only that code needs to be modified.

> [MK] Why can't use i2c_smbus_read_byte_data() as in tvp514x? Why send and receive(). This always create problems when multiple tasks use the driver, when while one send a command, get swapped and another use i2c to send/receive commands. It appears that you have used TVP5150 code as reference. There is a kernel oops discussion relating to tvp5150 in the linux-media list and it is attributed to this , I think.

Yes, I used TVP5150 as reference (not TI LSP code as you noted in the 
first comments). Hmm that is a good point for reentrant code using the 
driver. Will change accordingly.

[MK] Once this is submitted to community anyone can add modes as needed. So I suggest you focus on the above modes only for the initial patch you are sending to community.

[MK] vpfe capture will not consume this, but the sub device does. It gets it
as platform data. So you need to set polarity in the sub device based on this. Checkout tvp514x for usage.

>> [MK]You have used many modes in your driver. Why only these used here.

[MK] Please focus on the list of modes I have provided. We can always add other modes as needed later. For TI/Ridgerun requirement, the above mode list will suffice (unless Ridgerun has additional requirement that I am
not aware of). BTW, I have added a patch for the standards definition for
drivers internal development. Sneha will be sending you this patch. This
defines all modes for internal development and will be called
include/media/davinci/videohd.h. Include this file in the source code.
Note that this code can't be submitted to upstream.
