While this isn't strictly required, it may indicate that the sensor hasn't been tested much on DT-based systems. I agree that the configuration should come from the device tree, but I can't test that, so I'm tempted to let someone else implement it if the driver is actually still in use (I can also write a patch if someone can test it). > I wonder what kind of environment it is used in --- assuming it works > somewhere. > > > - if (ret) > > - return ret; > > - > > - if (cfg->flags & V4L2_MBUS_HSYNC_ACTIVE_LOW) > > - ret = ov6650_reg_rmw(client, REG_COMF, COMF_HREF_LOW, 0); > > - else if (cfg->flags & V4L2_MBUS_HSYNC_ACTIVE_HIGH) > > - ret = ov6650_reg_rmw(client, REG_COMF, 0, COMF_HREF_LOW); > > - if (ret) > > - return ret; > > - > > - if (cfg->flags & V4L2_MBUS_VSYNC_ACTIVE_HIGH) > > - ret = ov6650_reg_rmw(client, REG_COMJ, COMJ_VSYNC_HIGH, 0); > > - else if (cfg->flags & V4L2_MBUS_VSYNC_ACTIVE_LOW) > > - ret = ov6650_reg_rmw(client, REG_COMJ, 0, COMJ_VSYNC_HIGH); > > - if (ret) > > - return ret; > > - > > - /* > > - * Update the configuration to report what is actually applied to > > - * the hardware. > > - */ > > - return ov6650_get_mbus_config(sd, pad, cfg); > > -} > > - > > static const struct v4l2_subdev_video_ops ov6650_video_ops = { > > .s_stream = ov6650_s_stream, > > .g_frame_interval = ov6650_g_frame_interval, > > @@ -993,7 +957,6 @@ static const struct v4l2_subdev_pad_ops ov6650_pad_ops = { > > .get_fmt = ov6650_get_fmt, > > .set_fmt = ov6650_set_fmt, > > .get_mbus_config = ov6650_get_mbus_config, > > - .set_mbus_config = ov6650_set_mbus_config, > > }; > > > > static const struct v4l2_subdev_ops ov6650_subdev_ops = {

This driver was used with omap1_camera, removed from the tree a few years ago by Hans, despite my attempts to refresh it. I tried to keep ov6650 updated but I gave up due to lack of response to my submissions. That also blocked my attempts to rework and reintroduce omap1_camera. I think I'm still able to update my local (v4l2, non-mc) version of omap1_camera to the extent required to test any changes to ov6650. However, the OMAP1 platform does not support DT, and will probably never do. Then, I think that it makes sense to spend my time on that only if you (media maintainers) are not going to depreciate non-DT support any soon. Are you?

Thank you for the quick reply, and for the offer to test this. I understand your frustration, and the impossibility (with reasonable effort) to move OMAP1 to DT. This means that we would need to add platform data support to the ov6650 driver, and specify the platform data in the corresponding board file. On the ov6650 driver side I have no issue with that, and while platform data is deprecated for new platforms, it can be kept around for older ones as long as needed. I however don't know if changes to board files in arch/arm/mach-omap1 would be accepted. I also don't see any mention of ov6650 there, leading me to believe nobody can use this driver with the mainline kernel without resurecting the omap1_camera driver. I'm thus wondering if this would be a good use of your time, or if we should just merge this patch as-is. > > > I wonder what kind of environment it is used in --- assuming it works > > > somewhere. > > > > > > > - if (ret) > > > > - return ret; > > > > - > > > > - if (cfg->flags & V4L2_MBUS_HSYNC_ACTIVE_LOW) > > > > - ret = ov6650_reg_rmw(client, REG_COMF, COMF_HREF_LOW, 0); > > > > - else if (cfg->flags & V4L2_MBUS_HSYNC_ACTIVE_HIGH) > > > > - ret = ov6650_reg_rmw(client, REG_COMF, 0, COMF_HREF_LOW); > > > > - if (ret) > > > > - return ret; > > > > - > > > > - if (cfg->flags & V4L2_MBUS_VSYNC_ACTIVE_HIGH) > > > > - ret = ov6650_reg_rmw(client, REG_COMJ, COMJ_VSYNC_HIGH, 0); > > > > - else if (cfg->flags & V4L2_MBUS_VSYNC_ACTIVE_LOW) > > > > - ret = ov6650_reg_rmw(client, REG_COMJ, 0, COMJ_VSYNC_HIGH); > > > > - if (ret) > > > > - return ret; > > > > - > > > > - /* > > > > - * Update the configuration to report what is actually applied to > > > > - * the hardware. > > > > - */ > > > > - return ov6650_get_mbus_config(sd, pad, cfg); > > > > -} > > > > - > > > > static const struct v4l2_subdev_video_ops ov6650_video_ops = { > > > > .s_stream = ov6650_s_stream, > > > > .g_frame_interval = ov6650_g_frame_interval, > > > > @@ -993,7 +957,6 @@ static const struct v4l2_subdev_pad_ops ov6650_pad_ops = { > > > > .get_fmt = ov6650_get_fmt, > > > > .set_fmt = ov6650_set_fmt, > > > > .get_mbus_config = ov6650_get_mbus_config, > > > > - .set_mbus_config = ov6650_set_mbus_config, > > > > }; > > > > > > > > static const struct v4l2_subdev_ops ov6650_subdev_ops = {

I forgot to mention one more limitation of OMAP1 platform: it does not support CCF. With removal of v4l2-clk support from ov6650 a year ago, the driver is probably no longer usable with OMAP1 boards. > This means that we would need to add > platform data support to the ov6650 driver, and specify the platform > data in the corresponding board file.

Commenting just this and not the discussion later in this thread --- it is possible to support such sensor drivers without DT or ACPI nowadays, through software nodes. See e.g. drivers/media/pci/intel/ipu3/cio2-bridge.c .

See e.g. drivers/media/pci/intel/ipu3/cio2-bridge.c Thanks for bringing this possibility to my awareness, I didn't know it existed. AFAICS, I2C sensor drivers like ov6650 can now be provided by board files with device properties via i2c_board_info.swnode. If I find a solution to implement a non-v4l2-clk clock device in omap1_camera driver, I'll try to get back to updating ov6650 as time permits. Thanks, Janusz

For an endpoint at least three are required, meaning you'll need to do that separately.

Looking forward to that. Btw. I've taken the four patches you posted earlier, rebased them a little and pushed them here: <URL:https://git.linuxtv.org/sailus/media_tree.git/log/> Let me know if they're (not) fine.
