When the media device registration fails, don't call media_device_unregister since the device was never actually registered. When removing the module also call media_device_cleanup() to avoid a memory leak. Signed-off-by:

This patch makes the SoC camera framework as well as effectively the few remaining sensor drivers depend on BROKEN, rendering it uncompileable without changes in Kconfig. The purpose is to leave the code around if someone wishes to convert the drivers to the modern day V4L2 sub-device framework without having to go to see development history in git. Signed-off-by:

This addresses the below TODO item, no function related changes: - Prefix imgu for all public APIs, i.e. change ipu3_v4l2_register() to imgu_v4l2_register().

According to the ov5640 specification (2.7 power up sequence), host can access the sensor's registers 20ms after reset. Trying to access them before leads to undefined behavior and result in sporadic initialization errors. Signed-off-by:

The ov5640_try_frame_interval operation updates the FPS as per user input based on default ov5640_frame_rate, OV5640_30_FPS which is failed to update when user trigger 15fps. So, initialize the default ov5640_frame_rate to OV5640_15_FPS so-that it can satisfy to update all fps. Fixes: 5a3ad937 ("media: ov5640: Make the return rate type more explicit") Signed-off-by:

The register value lists for all the supported resolution settings all include a register address/value pair for setting the JPEG compression mode. With the exception of 1080p (which sets mode 2), all resolutions use mode 3. The only difference between mode 2 and mode 3 is that mode 2 may have padding data on the last line, while mode 3 does not add padding data. As these register values were from dumps of running systems, and the difference between the modes is quite small, using mode 3 for all configurations should be OK.

When compression is turned on, the on-bus data is framed according to the compression mode, and the height and width set in VFIFO_VSIZE and VFIFO_HSIZE. If these are not updated correctly, the sensor will send data framed in a manner unexpected by the capture interface, such as having more bytes per line than expected, and having the extra data dropped. This ultimately results in corrupted data. Set the two values when the media bus is configured for JPEG data, meaning the sensor would be in JPEG mode. Signed-off-by:

The OV5640 driver currently supports a static color bar pattern with a small vertical gamma gradient. The hardware also supports a color square pattern, as well as having a rolling bar for dynamic sequences. Add three more test patterns: - color bars with a rolling bar (but without the gamma gradient) - static color squares - color squares with a rolling bar Signed-off-by:
-
Chen-Yu Tsai authored
The transparent feature for test patterns blends the test pattern with an actual captured image. This makes the result non-static, subject to changes in the sensor's field of view. Test patterns should be predictable and deterministic, even if they are dynamic patterns. Disable the transparent feature of the test pattern. Signed-off-by:

The OV5640 can generate many types of test patterns, some with additional modifiers, such as a rolling bar, or gamma gradients. Add the bit definitions for all bits in the test pattern register, and use them to compose the values to be written to the register. Signed-off-by:
-
Chen-Yu Tsai authored
The OV5640 has many options for generating test patterns. Unfortunately there is only one V4L2 control for it. Thus the driver would need to list some or all combinations. Move the test_pattern_menu list before the ov5640_set_ctrl_test_pattern function that programs the hardware. This would allow us to add a matching list of values to program into the hardware, while keeping the two lists together for ease of maintenance. Signed-off-by:

The ADV748X_PAGE_WAIT is a fake page to insert arbitrary delays in the register tables. Its only usage was removed, so we can remove the handling and simplify the code. Reviewed-by:

The ADV748x is currently reset by writting a small table of registers to the device. The table lacks documentation and contains magic values to perform the actions, including using a fake register address to introduce a delay loop. Remove the table, and convert to code, documenting the purpose of the specific writes along the way. Signed-off-by:

When the adv748x driver is informed about a link being created from HDMI or AFE to a CSI-2 TX output, the 'link_setup()' callback is invoked. Make sure to implement proper routing management at link setup time, to route the selected video stream to the desired TX output. Signed-off-by:

Jacopo Mondi authored
Both the AFE and HDMI s_stream routines (adv748x_afe_s_stream() and adv748x_hdmi_s_stream()) have to enable the CSI-2 TX they are streaming video data to. With the introduction of dynamic routing between HDMI and AFE entities to TXA, the video stream sink needs to be set at run time, and not statically selected as the s_stream functions are currently doing. To fix this, store a reference to the active CSI-2 TX sink for both HDMI and AFE sources, and operate on it when starting/stopping the stream. Reviewed-by:

The power_up_tx() procedure needs to set a few registers conditionally to the selected video source, but it currently checks for the provided tx to be either TXA or TXB. With the introduction of dynamic routing between HDMI and AFE entities to TXA, checking which TX the function is operating on is not meaningful anymore. To fix this, store the subdevice of the source providing video data to the CSI-2 TX in the 'struct adv748x_csi2' representing the TX and check on it. Reviewed-by:

Jacopo Mondi authored
The ADV748x chip supports routing AFE output to either TXA or TXB. In order to support run-time configuration of video stream path, create an additional (not enabled) "AFE:8->TXA:0" link, and remove the IMMUTABLE flag from existing ones. Reviewed-by:

The sd argument of this macro can be a more complex expression. Since it is used 5 times in the macro it can be evaluated that many times as well. So assign it to a temp variable in the beginning and use that instead. This also avoids any potential side-effects of evaluating sd. Signed-off-by:

The capture compose rectangle was not getting updated when setting the source subdevice's source pad format. This causes the compose window to be zero (or not updated) at stream start unless the capture device format was set explicitly at the capture device node. Fix by moving the calculation of the capture compose rectangle to imx_media_mbus_fmt_to_pix_fmt(), and pass the rectangle to imx_media_capture_device_set_format().

The linked commit changed s_fmt/try_fmt to fail if num_planes is bogus. This, however, is against the spec, which mandates drivers to return a proper num_planes value, without an error. Replace the num_planes check and instead clamp it to a sane value, so we still make sure we don't overflow the planes array by accident.
