The bayer pixel order is defined by cropping the pixel array. If the sensor can do that, you should implement support for the crop selection rectangle instead. I think it'd be possible to add support for that later on as well if needed. > + if (ret) > + return ret; > + /* no break, for GBRG, we need v offset too */ > + case MEDIA_BUS_FMT_SBGGR10_1X10: > + return ov13858_increase_offset(ov13858, OV13858_REG_V_OFFSET); > + } > + > + return 0; > +} > + > +/* > + * Update analog gain > + */ > +static inline int ov13858_update_analog_gain(struct ov13858 *ov13858, > + struct v4l2_ctrl *ctrl) > +{ > + return ov13858_write_reg(ov13858, OV13858_REG_ANALOG_GAIN, > + OV13858_REG_VALUE_16BIT, ctrl->val); > +} > + > +/* Exposure control */ > +static int ov13858_update_exposure(struct ov13858 *ov13858, > + struct v4l2_ctrl *ctrl) > +{ > + int ret; > + u32 exposure, new_vts = 0; > + > + exposure = ctrl->val; > + if (exposure > ov13858->cur_mode->vts - 8) > + new_vts = exposure + 8; > + else > + new_vts = ov13858->cur_mode->vts; Instead of changing the vertical blanking interval implicitly, could you do it explicitly though the VBLANK control instead? As you do already control the vertical sync and provide the pixel rate control, how about adding a HBLANK control as well? I suppose it could be added later on as well.

Please just use zero. ov13858_stop_streaming() could have void return type, but perhaps it could complain out lout about a failing write. > + pm_runtime_put(&client->dev); > + } > + > + ov13858->streaming = enable; > + mutex_unlock(&ov13858->mutex); > + > + return ret; > + > +err_rpm_put: > + pm_runtime_put(&client->dev); > +err_unlock: > + mutex_unlock(&ov13858->mutex); > + > + return ret; > +} > + > +#ifdef CONFIG_PM > + > +static int ov13858_suspend(struct device *dev) > +{ > + struct i2c_client *client = to_i2c_client(dev); > + struct v4l2_subdev *sd = i2c_get_clientdata(client); > + struct ov13858 *ov13858 = to_ov13858(sd); > + > + if (ov13858->streaming) > + ov13858_stop_streaming(ov13858); > + > + return 0; > +} > + > +static int ov13858_resume(struct device *dev) > +{ > + struct i2c_client *client = to_i2c_client(dev); > + struct v4l2_subdev *sd = i2c_get_clientdata(client); > + struct ov13858 *ov13858 = to_ov13858(sd); > + int ret; > + > + if (ov13858->streaming) { > + ret = ov13858_start_streaming(ov13858); > + if (ret) > + goto error; > + } > + > + return 0; > + > +error: > + ov13858_stop_streaming(ov13858); > + ov13858->streaming = 0; > + return ret; > +} > + > +#else > + > +#define ov13858_suspend NULL > +#define ov13858_resume NULL Please use __maybe_unused as the smiapp driver does for the same, no need for #ifdefs. > + > +#endif /* CONFIG_PM */ > + > +/* Verify chip ID */ > +static inline int ov13858_identify_module(struct ov13858 *ov13858) > +{ > + struct i2c_client *client = v4l2_get_subdevdata(&ov13858->sd); > + int ret; > + u32 val; > + > + ret = ov13858_read_reg(ov13858, OV13858_REG_CHIP_ID, > + OV13858_REG_VALUE_24BIT, &val); > + if (ret) > + return ret; > + > + if (val != OV13858_CHIP_ID) { > + dev_err(&client->dev, "chip id mismatch: %x!=%x\n", > + OV13858_CHIP_ID, val); > + return -EIO; > + } > + > + return 0; > +} > + > +static const struct v4l2_subdev_video_ops ov13858_video_ops = { > + .s_stream = ov13858_set_stream, > +}; > + > +static const struct v4l2_subdev_pad_ops ov13858_pad_ops = { > + .enum_mbus_code = ov13858_enum_mbus_code, > + .get_fmt = ov13858_get_pad_format, > + .set_fmt = ov13858_set_pad_format, > + .enum_frame_size = ov13858_enum_frame_size, > +}; > + > +static const struct v4l2_subdev_sensor_ops ov13858_sensor_ops = { > + .g_skip_frames = ov13858_get_skip_frames, > +}; > + > +static const struct v4l2_subdev_ops ov13858_subdev_ops = { > + .video = &ov13858_video_ops, > + .pad = &ov13858_pad_ops, > + .sensor = &ov13858_sensor_ops, > +}; > + > +static const struct media_entity_operations ov13858_subdev_entity_ops = { > + .link_validate = v4l2_subdev_link_validate, > +}; > + > +static const struct v4l2_subdev_internal_ops ov13858_internal_ops = { > + .open = ov13858_open, > +}; > + > +static int ov13858_probe(struct i2c_client *client, > + const struct i2c_device_id *devid) > +{ > + struct ov13858 *ov13858; > + int ret; > + > + ov13858 = devm_kzalloc(&client->dev, sizeof(*ov13858), GFP_KERNEL); > + if (!ov13858) > + return -ENOMEM; > + > + /* Initialize subdev */ > + v4l2_i2c_subdev_init(&ov13858->sd, client, &ov13858_subdev_ops); > + > + /* Check module identity */ > + ret = ov13858_identify_module(ov13858); > + if (ret) { > + dev_err(&client->dev, "failed to find sensor: %d\n", ret); > + return ret; > + } > + > + mutex_init(&ov13858->mutex); > + > + /* Set default mode to max resolution */ > + ov13858->cur_mode = &supported_modes[0]; > + > + /* Set default bayer format with GRBG */ > + ov13858->cur_bayer_format = supported_bayer_format[0]; > + > + /* Set number of frames to skip */ > + ov13858->num_of_skip_frames = OV13858_NUM_OF_SKIP_FRAMES; > + > + ret = ov13858_init_controls(ov13858); > + if (ret) mutex_init() needs to be followed by mutex_destroy().

If the sensor can do that, you should implement support for the crop selection rectangle instead. Sorry, I'm new to imaging world but, as you can see, bayer order in this sensor IS DEFINED by both cropping and offset(where you start to read). Is there a strict (implicit or explicit) rule or specific reason that we should use only crop to apply expected bayer order, even though the bayer order in the sensor is defined by both crop and offset ?

I suppose it could be added later on as well. And presumably will be read only. I'll introduce VBLANK control with READ ONLY and the value of the control will be updated here. > > > + > > + ret = ov13858_group_hold_start(ov13858, 0); > > + if (ret) > > + return ret; > > + > > + ret = ov13858_write_reg(ov13858, OV13858_REG_VTS, > > + OV13858_REG_VALUE_16BIT, new_vts); > > + if (ret) > > + return ret; > > + > > If you want group hold for that, too, we need a new callback (or two) for the control handler I believe.

Checking the usage_count directly does not look like something a driver should be doing. Agree, I really wanted to use any helper(accesor) method for this but when I checked the pm_runtime_active() it wasn't good enough. Anyway I just found better one for this case.

For now, I believe mostly mutex_destroy() is for debug purpose. we can have it for porting and development.

The bayer pixel order is defined by cropping the pixel array. If the sensor can do that, you should implement support for the crop selection rectangle instead. I think it'd be possible to add support for that later on as well if needed. > + if (ret) > + return ret; > + /* no break, for GBRG, we need v offset too */ > + case MEDIA_BUS_FMT_SBGGR10_1X10: > + return ov13858_increase_offset(ov13858, OV13858_REG_V_OFFSET); > + } > + > + return 0; > +} > + > +/* > + * Update analog gain > + */ > +static inline int ov13858_update_analog_gain(struct ov13858 *ov13858, > + struct v4l2_ctrl *ctrl) > +{ > + return ov13858_write_reg(ov13858, OV13858_REG_ANALOG_GAIN, > + OV13858_REG_VALUE_16BIT, ctrl->val); } > + > +/* Exposure control */ > +static int ov13858_update_exposure(struct ov13858 *ov13858, > + struct v4l2_ctrl *ctrl) > +{ > + int ret; > + u32 exposure, new_vts = 0; > + > + exposure = ctrl->val; > + if (exposure > ov13858->cur_mode->vts - 8) > + new_vts = exposure + 8; > + else > + new_vts = ov13858->cur_mode->vts; Instead of changing the vertical blanking interval implicitly, could you do it explicitly though the VBLANK control instead? As you do already control the vertical sync and provide the pixel rate control, how about adding a HBLANK control as well? I suppose it could be added later on as well.

The CROP selection rectangle is the interface to configure crop an area from the parent rectangle (NATIVE_SIZE in this case).

HBLANK would be read-only since the register list that you have might contain dependencies to the horizontal blanking so you can't change that. The VBLANK control, instead, should not be read-only to allow controlling the frame rate and also controlling the exposure without affecting the frame rate. > > > > > > + > > > + ret = ov13858_group_hold_start(ov13858, 0); > > > + if (ret) > > > + return ret; > > > + > > > + ret = ov13858_write_reg(ov13858, OV13858_REG_VTS, > > > + OV13858_REG_VALUE_16BIT, new_vts); > > > + if (ret) > > > + return ret; > > > + > > > > If you want group hold for that, too, we need a new callback (or two) > > for the control handler I believe. > > I don't understand wht this means. Can you give me detail ? The V4L2 control framework calls the s_ctrl() callback in the driver to set control values. The driver however doesn't know how many controls there will be to set or when the last control of the set would be conveyed to the driver.

If possible, can you review that one also ? I'm learning many things from your review comments. I think in V2, I've addressed most of comments except raw bayer format. For ray bayer format, for now, I intentionally don't support crop since it requires more complexity to meet request from _set_pad_format() while keeping FOV for the resolutions with the same ratio(4:3 or 16:9). Yes, it is hacky but I thought it's OK unless there's a need to support crop. Hm..... I'm thinking drop "bayer order change" since it is not that meaningful. Should I ? For VBLANK, I realized I made wrong comments just after I send it. Yeas, it shouldn't be read-only. So you can see that VBLANK I added in V2 is NOT read-only.
