The ar0521_write_mode() function explicitly programs the exposure time register and the test pattern register, which are now setup by the call to __v4l2_ctrl_handler_setup() in ar0521_set_stream(). Removing those register writes from ar0521_write_mode() reduces the function to two operations: geometry configuration and pll configuration. Move geomerty configuration in the ar0521_set_stream() caller and rename ar0521_write_mode() to ar0521_pll_config(). Signed-off-by:

Adjust the control limits for V4L2_CID_VBLANK, V4L2_CID_HBLANK and V4L2_CID_EXPOSURE when a new format is applied to the sensor. Update the exposure control limits when a new blanking value is applied and change the controls initialization to use valid values for the default format. The exposure control default value is changed to report the default value of register 0x3012. Signed-off-by:

The MT9P006 sensor driver sporadically fails to probe because the sensor responds with a NACK condition to I2C address on the bus during an attempt to read the sensor MT9P031_CHIP_VERSION register in mt9p031_registered(). Neither the MT9P006 nor MT9P031 datasheets are clear on reset signal timing. Older MT9M034 [1] datasheet provides those timing figures in Appendix-A and indicates it is necessary to wait 850000 EXTCLK cycles before starting any I2C communication. Add such a delay, which does make the sporadic I2C NACK go away, so it is likely similar constraint applies to this sensor. [1] https://www.onsemi.com/pdf/datasheet/mt9m034-d.pdfSigned-off-by:

The mt9p031_init_cfg() already calls __mt9p031_get_pad_crop(), which correctly calls v4l2_subdev_get_try_crop() on V4L2_SUBDEV_FORMAT_TRY or returns &mt9p031->crop on V4L2_SUBDEV_FORMAT_ACTIVE. No need to call v4l2_subdev_get_try_crop() in mt9p031_init_cfg() again in case of both V4L2_SUBDEV_FORMAT_TRY and V4L2_SUBDEV_FORMAT_ACTIVE. This also fixes a splat generated by this call since commit 2ba3e385 ("media: v4l: subdev: Fail graciously when getting try data for NULL state") because v4l2_subdev_get_try_crop() is called with sd_state = NULL in mt9p031_init_cfg().

Previously regulators were enabled on probe and never again. However, as regulators are disabled on power off. After a second power off the regulator counter will underflow. Plus regulators are not required for probing the sensor, but for streaming. Fix this by enabling regulators on power on to balance regulator counter properly. Signed-off-by:

Still there are archs/platforms which do not support the common clk framework. If such a platform is used in combination with the module enabled the compiler will throw an error. Since the clock has stubs if not selected we can drop it, so it is up to the arch/platform to select the correct clock framework.

The imx7-media-csi driver, currently in staging, is ready for prime-time. The staging TODO file lists a few items specific to that driver, that are already addressed (the "all of the above" part) or can be addressed later: - The frame interval monitoring support is a software mechanism to monitor the device for unexpected stalls, and should be part of the V4L2 core if desired. - Restricting the support media bus formats based on the SoC integration only aims at reducing userspace confusion by not enumerating options that are known not to be possible, it won't cause regressions if handled later. Move the description of the media bus format restriction TODO item to the driver, drop the other TODO items, and move the driver out of staging. Signed-off-by:

Commit 9babbbaa ("media: imx: imx7-media-csi: Use dual sampling for YUV 1X16") set BIT_MIPI_DOUBLE_CMPNT in the CR18 register for 16-bit YUV formats in imx7_csi_configure(). The CR18 register is always updated with read-modify-write cycles, so if a 16-bit YUV format is selected, the bit will stay set forever, even if the format is changed. Fix it by clearing the bit at the beginning of the imx7_csi_configure() function. While at it, swap two of the bits being cleared to match the MSB to LSB order. This doesn't cause any functional change. Fixes: 9babbbaa ("media: imx: imx7-media-csi: Use dual sampling for YUV 1X16") Signed-off-by:
