2024-11-07media: i2c: Drop HAS_EVENTS and event handlersTommaso Merciai
v4l2_subdev_init_finalize() already sets the HAS_EVENTS flag if a control handler is set, and subdev_do_ioctl() uses v4l2_ctrl_subdev_subscribe_event() and v4l2_event_subdev_unsubscribe() as defaults if the subdev doesn't have .(un)subscribe. Let's drop the HAS_EVENTS flag and event handlers.

2024-10-16media: i2c: imx290: Check for availability in probe()Benjamin Bara
Currently, the V4L2 subdevice is also created when the device is not available/connected. From userspace perspective, there is no visible difference between a working and not-working subdevice (except when trying it out). This commit adds a simple preparation step, which includes an availability check, before the subdev is initialized.

2024-10-16media: i2c: imx290: Avoid communication during probe()Benjamin Bara
As we don't know the mode during probe(), it doesn't make sense to update the sensors' registers with assumptions. As imx290_set_ctrl(), which is responsible for the happening communication, already ensures that there is no communication with a suspended sensor, put the sensor to suspend before calling it. To clarify the dependency of the PM runtime to the link of the subdev and the imx290 instance, put the block together.

This register is not described in the public available imx290 datasheet. Additionally, a read returns '0x07d0' for an imx327lqr and also for an imx462, which means it cannot be used to distinguish between those two imx290 derivatives.

2023-12-04media: v4l2-subdev: Rename .init_cfg() operation to .init_state()Laurent Pinchart
The subdev .init_cfg() operation is affected by two issues: - It has long been extended to initialize a whole v4l2_subdev_state instead of just a v4l2_subdev_pad_config, but its name has stuck around. - Despite operating on a whole subdev state and not being directly exposed to the subdev users (either in-kernel or through the userspace API), .init_cfg() is categorized as a subdev pad operation. This participates in making the subdev API confusing for new developers. Fix it by renaming the operation to .init_state(), and make it a subdev internal operation.

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

The sensor supports H & V flips, so add the relevant hooks for V4L2_CID_HFLIP and V4L2_CID_VFLIP to configure them. Note that the Bayer order is maintained as the readout area shifts by 1 pixel in the appropriate direction (note the comment about the top margin being 8 pixels whilst the bottom margin is 9). The V4L2_SEL_TGT_CROP region is therefore adjusted appropriately.

2023-03-20media: i2c: imx290: Fix the pixel rate at 148.5Mpix/sDave Stevenson
The datasheet lists the link frequency changes between 1080p and 720p modes. This is correct that the link frequency changes as measured on an oscilloscope. Link frequency is not necessarily the same as pixel rate. The datasheet gives standard configurations for 1080p and 720p modes at a number of frame rates. Looking at the 1080p mode it gives: HMAX = 0x898 = 2200 VMAX = 0x465 = 1125 2200 * 1125 * 60fps = 148.5MPix/s Looking at the 720p mode it gives: HMAX = 0xce4 = 3300 VMAX = 0x2ee = 750 3300 * 750 * 60fps = 148.5Mpix/s This driver currently scales the pixel rate proportionally to the link frequency, however the above shows that this is not the correct thing to do, and currently all frame rate and exposure calculations give incorrect results. Correctly report the pixel rate as being 148.5MPix/s under any mode.

To improve this further, also use the pm_ptr() helper that lets the dev_pm_ops get dropped entirely when CONFIG_PM is disabled. A related mistake happened in the of_match_ptr() macro here, which like SET_RUNTIME_PM_OPS() requires the match table to be marked as __maybe_unused, though I could not reproduce building this without CONFIG_OF.
