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:

The CSI hardware compatible with this driver handles buffers using a ping-pong mechanism with two sets of destination addresses. Normally, when an interrupt comes in to signal the completion of one buffer, say FB1, it assigns the next buffer in the queue to the next FB1, and the hardware starts to capture into FB2 in the meantime. In a buffer underrun situation, in the above example without loss of generality, if a new buffer is queued before the interrupt for FB1 comes in, we can program the buffer into FB2 (which is programmed with a dummy buffer, as there is a buffer underrun). This of course races with the interrupt that signals FB1 completion, as once that interrupt comes in, we are no longer guaranteed that the programming of FB2 was in time and must assume it was too late. This race is resolved partly by locking the programming of FB2. If it came after the interrupt for FB1, then the variable that is used to determine which FB to program would have been swapped by the interrupt handler. This alone isn't sufficient, however, because the interrupt could still be generated (thus the hardware starts capturing into the other fb) while the fast-tracking routine has the irq lock. Thus, after programming the fb register to fast-track the buffer, the isr also must be checked to confirm that an interrupt didn't come in the meantime. If it has, we must assume that programming the register for the fast-tracked buffer was not in time, and queue the buffer normally. Signed-off-by:

The ov2680_720p_30fps register init list used for the 1296x736 resolution sets the hsize register to 1296 and the vsize register to 736. This is actually the right thing to do when combined with the atomISP2 because the ISP requires 16 bytes padding leaving userspace to see 1280x720. But the resolution list entries for this was incorrectly reporting the resolution being send to the ISP as already being 1280x720, leaving usespace to see 1274x704 as resolution. Worse then userspace seeing a weird resolution selecting the 1280x720 sensor resolution (which in reality is sending 1296x736) to the ISP was causing the ISP to hang on Cherry Trail based tablets (Bay Trail works fine for some reason). This commit also adds a bunch of comments annotating what the various register writes the init lists are doing. Reviewed-by:

atomisp_ospm_dphy_up() is an empty function now and atomisp_ospm_dphy_down() contains a couple of checks + goto done statements which don't matter since the function always ends up at the done label regardless and then it does 1 pci-config write. Move the single pci-config write directly to atomisp_power_off() and remove the atomisp_ospm_dphy_up()/_down() functions. Reviewed-by:

The only thing which atomisp_ospm_dphy_down() does is disable the CSI pins, but if we failed to probe the ISP then these will never have been enabled (because the ISP never started streaming). So the atomisp_ospm_dphy_down() call in the probe error path is unnecessary, remove it. Reviewed-by:

atomisp_css_init() is always called after calling atomisp_power_on() either directly or through getting a runtime-pm reference. Likewise atomisp_css_uninit() is always called after calling atomisp_power_off(). Move the call site of these 2 functions to inside atomisp_power_on() / atomisp_power_off() to make this more explicit. Note this makes atomisp_reset() also set isp_fatal_error on atomisp_power_on() errors, where as before it only did this on atomisp_css_init() errors. This behavior change is for the better, since power-on failing is pretty fatal too. Reviewed-by:
