Re: [PATCH 0/6] davinci vpbe: V4L2 Display driver for DM644X
Hi Manju, I've reviewed the other patches as well. The only one for which I had comments was patch 2/6. However, what I think would be useful here is to have an overview document, either as part of a source or header, or as a separate text document. It is not easy to get a good overview of how everything fits together, and a document that describes the various parts and how they fit together would be very benificial. I am thinking in particular of vendors building a new board based on this device: how and where do you define new i2c display devices, how are they initialized, etc. Regards, Hans On Monday, November 08, 2010 15:54:05 Manjunath Hadli wrote: > This driver is written for Texas Instruments's DM644X VPBE IP. > This SoC supports 2 video planes and 2 OSD planes as part of its > OSD (On Screen Display) block.

Almost right. You need to put the vpbe_osd into an anonymous union:
/* SoC IP specific ops */
union {
const struct vpbe_osd_ops *vpbe_osd;
};
This way other private ops can be added without increasing the size of the
struct.
This should work like a charm. I had this idea from the very beginning,
but nobody needed it until now.
Regards,
Hans

Re: [PATCH 0/6] davinci vpbe: V4L2 Display driver for DM644X
Hans,
Is it possible to extend the sub device ops to include SoC ip sub
device specific ops? I remember I had posted this question some time
back and you had proposed to add something like this. Just want to
check if that is still valid. This would make this driver
implementation little more cleaner.
struct vpbe_osd_ops;
struct v4l2_subdev_ops {
const struct v4l2_subdev_core_ops *core;
const struct v4l2_subdev_tuner_ops *tuner;
const struct v4l2_subdev_audio_ops *audio;
const struct v4l2_subdev_video_ops *video;
const struct v4l2_subdev_vbi_ops*vbi;
const struct v4l2_subdev_ir_ops *ir;
const struct v4l2_subdev_sensor_ops *sensor;
/* SoC IP specific ops */
const struct vpbe_osd_ops *vpbe_osd;
};
The struct vpbe_osd_ops will be defined in the osd sub device header
file. This will allow the host/bridge driver to call osd specific
operations like standard sub dev ops.
Any comments?

Re: [PATCH 0/6] davinci vpbe: V4L2 Display driver for DM644X
Manjunath, Thank you for putting up this patch together. I didn't see the 1/6 of this series in the mailing list. Also it appears as if the patch came from me. Please add my sign-off as second, you being the first.
