The ov5645 driver reports as its unique supported format MEDIA_BUS_FMT_UYVY8_2X8, which is not correct as the sensor uses the MIPI CSI-2 serial bus. Fix that by using MEDIA_BUS_FMT_UYVY8_1X16 instead. Signed-off-by:

Matching on device fwnode handles is deprecated in favour of endpoint fwnode handles. Switch the __v4l2_async_nf_add_fwnode_remote() function to use the latter. The match code handles backward compatibility by falling by to the device fwnode handle, so this shouldn't introduce any regression. Signed-off-by:

Primarily request a specific revision of the IPU3 firmware that the driver is known to work with, irci_irci_ecr-master_20161208_0213_20170112_1500.bin. Some distros only ship this while others provide a symlink called ipu3-fw.bin, which the driver only requested previously. Signed-off-by:

For the AF configuration, if the rightmost stripe is used, the AF scene will be at the incorrect location of the sensor. The AF coordinate may be set to the right part of the sensor. This configuration would lead to x_start being greater than the down_scaled_stripes offset and the leftmost stripe would be disabled and only the rightmost stripe is used to control the AF coordinate. If the x_start doesn't perform any adjustments, the AF coordinate will be at the wrong place of the sensor since down_scaled_stripes offset would be the new zero of the coordinate system. In this patch, if only the rightmost stripe is used, x_start should minus down_scaled_stripes offset to maintain its correctness of AF scene coordinate. Signed-off-by:

Upon an async fwnode match, there's some typical behaviour that the notifier and matching subdev will want to do. For example, a notifier representing a sensor matching to an async subdev representing its VCM will want to create an ancillary link to expose that relationship to userspace. To avoid lots of code in individual drivers, try to build these links within v4l2 core. Signed-off-by:

To describe in the kernel the connection between devices and their supporting peripherals (for example, a camera sensor and the vcm driving the focusing lens for it), add a new type of media link to introduce the concept of these ancillary links.

The original implementation removes reverse links for any input link and assumes the presense of sink/source. It fails when the link is a not a data link. media_entity_remove_links when there's an ancillary link can also fail. We only need to remove reverse links for a data link. Signed-off-by:

Add support for MEDIA_BUS_FMT_JPEG_1X8 media bus code to the CSIS driver. The MEDIA_BUS_FMT_JPEG_1X8 code is mapped to the RAW8 CSI-2 Data Type, while the CSI-2 specification suggests to use User Defined Data Type 1. As reported in the comment, the CSIS interface captures arbitrary Data Types by using a pixel sampling mode not supported by the IP core connected to it on i.MX SoCs. As some sensors, such as OV5640, support sending JPEG data on the RAW8 Data Type and capture operations work correcty with such configuration, map MEDIA_BUS_FMT_JPEG_1X8 to Data Type 0x2a.

Allow drivers to change the transmit timeout value, i.e. after how long should a transmit be considered 'lost', i.e. the corresponding cec_transmit_done_ts was never called. Some CEC devices have their own timeout, and so this timeout value must be longer than that hardware timeout value. If it is shorter then the framework would consider the transmit lost, even though it is effectively still in progress at the hardware level. Signed-off-by:

Use call_(void_)op consistently in the CEC core framework. Ditto for the cec pin ops. And check if !adap->devnode.unregistered before calling each op. This avoids calls to ops when the device has been unregistered and the underlying hardware may be gone. Signed-off-by:

These two helper functions return true if the received message contains the result of a previous non-blocking transmit. Either the tx_status result (cec_msg_recv_is_tx_result) of the transmit, or the rx_status result (cec_msg_recv_is_rx_result) of the reply to the original transmit. Signed-off-by:
-
Hans Verkuil authored
The results of non-blocking transmits were not correctly communicated to userspace. Specifically: 1) if a non-blocking transmit was canceled, then rx_status wasn't set to 0 as it should. 2) if the non-blocking transmit succeeded, but the corresponding reply never arrived (aborted or timed out), then tx_status wasn't set to 0 as it should, and rx_status was hardcoded to ABORTED instead of the actual reason, such as TIMEOUT. In addition, adap->ops->received() was never called, so drivers that want to do message processing themselves would not be informed of the failed reply. Signed-off-by:
-
Hans Verkuil authored
If a transmit-in-progress was canceled, then, once the transmit is done, mark it as aborted and refrain from retrying the transmit. To signal this situation the new transmit_in_progress_aborted field is set to true. The old implementation would just set adap->transmitting to NULL and set adap->transmit_in_progress to false, but on the hardware level the transmit was still ongoing. However, the framework would think the transmit was aborted, and if a new transmit was issued, then it could overwrite the HW buffer containing the old transmit with the new transmit, leading to garbled data on the CEC bus.

Don't enable/disable the adapter if the first fh is opened or the last fh is closed, instead do this when the adapter is configured or unconfigured, and also when we enter Monitor All or Monitor Pin mode for the first time or we exit the Monitor All/Pin mode for the last time. However, if needs_hpd is true, then do this when the physical address is set or cleared: in that case the adapter typically is powered by the HPD, so it really is disabled when the HPD is low. This case (needs_hpd is true) was already handled in this way, so this wasn't changed. The problem with the old behavior was that if the HPD goes low when no fh is open, and a transmit was in progress, then the adapter would be disabled, typically stopping the transmit immediately which leaves a partial message on the bus, which isn't nice and can confuse some adapters. It makes much more sense to disable it only when the adapter is unconfigured and we're not monitoring the bus, since then you really won't be using it anymore. To keep track of this store a CEC activation count and call adap_enable only when it goes from 0 to 1 or back to 0. Signed-off-by:
