Dynamic frame rate changes could therefore not be achieved. Separate out programming TIMING_VTS so that it is triggered by set_ctrl(V4L2_CID_VBLANK) Signed-off-by: Dave Stevenson --- drivers/media/i2c/ov9282.c | 29 ++++++++++++++++------------- 1 file changed, 16 insertions(+), 13 deletions(-) diff --git a/drivers/media/i2c/ov9282.c b/drivers/media/i2c/ov9282.c index 183283d191b1..5ddef6e2b3ac 100644 --- a/drivers/media/i2c/ov9282.c +++ b/drivers/media/i2c/ov9282.c @@ -419,22 +419,15 @@ static int ov9282_update_controls(struct ov9282 *ov9282, */ static int ov9282_update_exp_gain(struct ov9282 *ov9282, u32 exposure, u32 gain) { - u32 lpfr; int ret; - lpfr = ov9282->vblank + ov9282->cur_mode->height; - - dev_dbg(ov9282->dev, "Set exp %u, analog gain %u, lpfr %u", - exposure, gain, lpfr); + dev_dbg(ov9282->dev, "Set exp %u, analog gain %u", + exposure, gain); ret = ov9282_write_reg(ov9282, OV9282_REG_HOLD, 1, 1); if (ret) return ret; - ret = ov9282_write_reg(ov9282, OV9282_REG_LPFR, 2, lpfr); - if (ret) - goto error_release_group_hold; - ret = ov9282_write_reg(ov9282, OV9282_REG_EXPOSURE, 3, exposure << 4); if (ret) goto error_release_group_hold; @@ -465,6 +458,7 @@ static int ov9282_set_ctrl(struct v4l2_ctrl *ctrl) container_of(ctrl->handler, struct ov9282, ctrl_handler); u32 analog_gain; u32 exposure; + u32 lpfr; int ret; switch (ctrl->id) { @@ -482,10 +476,14 @@ static int ov9282_set_ctrl(struct v4l2_ctrl *ctrl) OV9282_EXPOSURE_OFFSET, 1, OV9282_EXPOSURE_DEFAULT); break; + } + + /* Set controls only if sensor is in power on state */ + if (!pm_runtime_get_if_in_use(ov9282->dev)) + return 0; + + switch (ctrl->id) { case V4L2_CID_EXPOSURE: - /* Set controls only if sensor is in power on state */ - if (!pm_runtime_get_if_in_use(ov9282->dev)) - return 0; exposure = ctrl->val; analog_gain = ov9282->again_ctrl->val; @@ -495,14 +493,19 @@ static int ov9282_set_ctrl(struct v4l2_ctrl *ctrl) ret = ov9282_update_exp_gain(ov9282, exposure, analog_gain); - pm_runtime_put(ov9282->dev); + break; + case V4L2_CID_VBLANK: + lpfr = ov9282->vblank + ov9282->cur_mode->height; + ret = ov9282_write_reg(ov9282, OV9282_REG_LPFR, 2, lpfr); break; default: dev_err(ov9282->dev, "Invalid control %d", ctrl->id); ret = -EINVAL; } + pm_runtime_put(ov9282->dev); + return ret; }
