Since commit cc62c747 ("media: allegro: add missed checks in allegro_open()") the allegro device does provide v4l2 controls to user space anymore. The reason is that v4l2_fh_init() initializes fh->ctrl_handler to vdev->ctrl_handler, which invalidates the previous driver override of the ctrl_handler. Therefore, v4l2_fh_init() must be called before the driver overrides the fh->ctrl_handler with its own handler. Move the initialization of the fh back to the top, as the initialization does not does not need to be reverted on errors, but it is enough to free the channel.

The driver doesn't really support V4L2_PIX_FMT_Y16, as there's no 16-bit greyscale media bus code defined by the kernel. It (ab)uses the format to capture 10-bit and 12-bit greyscale formats. Fix it to properly support MEDIA_BUS_FMT_Y10_1X10 and MEDIA_BUS_FMT_Y12_1X12 instead. Signed-off-by:

Commit 4791bd7d ("media: imx: Try colorimetry at both sink and source pads") reworked the way that formats are set on the sink pad of the CSI subdevice, and accidentally removed video field handling. Restore it by defaulting to V4L2_FIELD_NONE if the field value isn't supported, with the only two supported value being V4L2_FIELD_NONE and V4L2_FIELD_INTERLACED.

The imx7_csi_dma_reflash() function starts by reading the unrelated register CSI_CSICR18 to then overwrite the read value with a read from register CSI_CSICR3. This is likely due to a bad copy&paste, and is not needed. Remove the extraneous read from register CSI_CSICR18.

Enable filtering based on CSI-2 data type. Otherwise sources that send multiple data types (such as sensors that send embedded data) will not be properly supported. They will both result in additional non-image lines being captured, and in the receiver being confused as it doesn't resynchronise on vsync. Signed-off-by:

Make sure to check that we have two alternate settings and at least one endpoint before accessing the second altsetting structure and dereferencing the endpoint arrays. This specifically avoids dereferencing NULL-pointers or corrupting memory when a device does not have the expected descriptors. Note that the sanity check in cit_get_packet_size() is not redundant as the driver is mixing looking up altsettings by index and by number, which may not coincide.

From the measured hardware signal, OV5695 reset pin goes high for a short period of time during boot-up. From the sensor specification, the reset pin is active low and the DT binding defines the pin as active low, which means that the values set by the driver are inverted and thus the value requested in probe ends up high. Fix it by changing probe to request the reset GPIO initialized to high, which makes the initial state of the physical signal low. In addition, DOVDD rising must occur before DVDD rising from spec., but regulator_bulk_enable() API enables all the regulators asynchronously. Use an explicit loops of regulator_enable() instead. For power off sequence, it is required that DVDD falls first. Given the bulk API does not give any guarantee about the order of regulators, change the driver to use regulator_disable() instead. The sensor also requires a delay between reset high and first I2C transaction, which was assumed to be 8192 XVCLK cycles, but 1ms is recommended by the vendor. Fix this as well. Signed-off-by:

When supporting Rpi Camera v2 Module on the RZ/G2E, found the driver had some issues with rcar mipi-csi driver. The sensor never entered into LP-11 state. The powerup sequence in the datasheet[1] shows the sensor entering into LP-11 in streaming mode, so to fix this issue transitions are performed from "streaming -> standby" in the probe() after power up. With this commit the sensor is able to enter LP-11 mode during power up, as expected by some CSI-2 controllers.

The debug output for tvp5150_selmux() isn't really intuitive. Register values are printed decimal formatted and the input/output driver states are printed as enum. Even more the "normal" output enum mapps to zero so a active output will printing output=0 and a inactive output=1. Change this by brinting the register values hex formatted and the states as more readable string. Signed-off-by:

The tvp5150 accepts NTSC(M,J,4.43), PAL (B,D,G,H,I,M,N) and SECAM video data and is able to auto-detect the input signal. The auto-detection does not work if the connector does not receive an input signal and the tvp5150 might not be configured correctly. This misconfiguration leads into wrong decoded video streams if the tvp5150 gets powered on before the video signal is present. Limit the supported sdtv standards according to the actual selected connector to avoid a misconfiguration. Signed-off-by:
