snr_mbus_fmt is a local variable pointing to a substruct of another local variable which really just makes the code harder to read / follow, so drop it. And likewise also drop the stream_info local variable. Reviewed-by:

The custom V4L2_CID_FMT_AUTO control, which defaults to true controls whether the atomisp driver will automatically configure the sensor and ISP settings to match. This is necessary to make normal v4l2 apps to work. We do eventually want to add libcamera support, but even then moving this to userspace does not give any added value, while breaking classic v4l2 apps. Moreover we really don't know all the exact pipeline constraints, so moving this to userspace/libcamera will be tricky thus it is best to keep the current in kernel code for this and make the kernel unconditionally do this.

The DSDT of all Windows BYT / CHT devices which I have seen has proper ACPI powermagement for the clk and regulators used by the sensors. So there is no need for the whole custom atomisp_gmin custom code to disable the ACPI pm and directly poke at the PMIC for this. Replace all the atomisp_gmin usage with using the new atomisp_register_sensor_no_gmin() / atomisp_unregister_subdev() helpers which allow registering a sensor with the atomisp code without using any of the atomisp_gmin power-management code. Note eventually these calls should be replaced by the standard v4l2_async_register_subdev_sensor() mechanism. But this first requires a bunch of work to the atomisp main code to make it set the necessary fwnodes up, similar to how drivers/media/pci/intel/ipu3/cio2-bridge.c does this. Reviewed-by:

Use devm_kzalloc() to allocate the data struct. It is always free-ed as the last step of probe-error-exit or remove, so it can be devm-managed. This will make unwinding things easier when support is added to the gc0310 code to use standard GPIO APIs instead of the custom atomisp_gmin code. This also allows dropping the out_free label and use direct return on errors. This may seem like a functional change since the out_free label also did a v4l2_device_unregister_subdev() but at the 1 changed return the device is not registered yet, so that always is a no-op and can be dropped.

Exposure and gain control should use standard v4l2 controls, not a custom ioctl. The next patch in this series will re-add support as standard controls, this is split into 2 patches for easier reviewing. Reviewed-by:

The sensor does not have automatic exposure so the exposure cannot change underneath us. And the control is not marked volatile in it flags, so the .g_volatile_ctrl callback will never get called. Remove the current broken read-only (no s_ctrl implementation) exposure ctrl, this will be replaced with a proper r/w exposure control relying on the kernel caching the last set value (so non volatile).

Fix 3 error handling issues: 1. In ov2680_s_stream(), when pm_runtime_get_sync() fails it will still have incremented the pm-runtime reference count so we need to call pm_runtime_put() 2. In ov2680_s_stream() sensor->is_streaming should always be set to false when the sensor is powered-off even on i2c-communication errors. 3. In ov2680_probe(), call ov2680_remove() on ov2680_s_config() errors, so that pm_runtime_disable() is properly called to disable the runtime-pm which has been enabled before the ov2680_s_config() call.

Use the new v4l2_get_acpi_sensor_info() for the GPIO lookups, this uses the special Intel _DSM method to get more info about the GPIOs like their function and their polarity. Reviewed-by:

Hans de Goede authored
ACPI nodes describing sensors on atomisp devices implement a "79234640-9e10-4fea-a5c1-b5aa8b19756f" Device Specific Method (DSM) to get info about the GPIOs. Using this method is necessary to figure out which ACPI GPIO resource is "reset" and which one is "powerdown" and this is also necessary to figure out the correct polarity of the pins. One example where this is necessary is the GC0310 sensor. The current GC0310 code hardcodes reset as being active-low and power-down as being active-high. This works on a number of devices such as the mpman converter 9. But it is wrong for the Chuwi Vi8 CWI501 where the powerdown pin is active-low. Rather then adding DMI quirks for this, add a helper for this, which can be shared between sensor-drivers. This new helper optionally also returns a string identifying the exact sensor-module used, which might be useful if any module specific behvior is necessary in the sensor driver. This uses the DSM directly on the sensor device's ACPI node. This is different from later Intel hardware (IPU3 / IPU6) which has a separate INT3472 node (with its own driver) with this info. Since there is no separate ACPI node to which we can bind to register GPIO lookups, this unfortunately means that all sensor drivers which may be used on BYT or CHT hw need to call this new helper. Note for now this function is being added to atomisp_gmin_platform.c, but once things are ready to move atomisp over to using generic sensor drivers this will need to become a generic v4l2 sensor helper. but this will require upstream discussion first.

(patch based on intel-aero kernel patch: https://github.com/intel-aero/meta-intel-aero-base/commit/26fc9fe5030b63bc9dcf0b5f32981948911ca272) Here is the original commit message from the aforementioned patch: From 26fc9fe5030b63bc9dcf0b5f32981948911ca272 Mon Sep 17 00:00:00 2001 From: Lucas De Marchi <lucas.demarchi@intel.com> Date: Fri, 7 Jul 2017 14:23:53 -0700 Subject: [PATCH] linux-yocto: Remove remaining instance of call to trace_printk It's not sufficient to leave trace_printk() out of "normal call chains" since the way trace infrastructure works is that it will allocate the trace_printk buffers if the symbol is there (by using a separate section for the function and checking if __start_* and __stop_* symbols are different. Therefore, even if the default value for the param tells the module to use printk(), just the fact that it can be changed to trace_printk() means the initialization code will be called. The trace_printk() was replaced by pr_info() on commit 3d81099c ("media: atomisp: Replace trace_printk by pr_info") for the upstreamed atomisp, too. However, as the aforementioned commit message says, there is still a remaining instance. This causes the "trace_printk() being used" kernel warning message to still appear on the first driver load. Based on the aforementioned patch, this patch removes the call to ftrace_vprintk(). This removes that kernel warning. In addition to this, this patch also removes the following now unused things: - now empty atomisp_css2_dbg_ftrace_print() - trace_printk option from dbg_func kernel parameter Link: https://lore.kernel.org/r/20211017161958.44351-15-kitakar@gmail.comSigned-off-by:

Continues mode is a special mode where 2 /dev/video devices can be active at the same time. Either the video-preview + video nodes or the viewfinder (for still capture) + capture nodes. For the video-preview + video-recording case modern userspace will use a single stream multiplexed by pipewire. The still-capture case is extra special only starting the preview stream and then relying on a custom ATOMISP_IOC_S_CONT_CAPTURE_CONFIG ioctl to set things up followed by a second stream on to capture the amount of configured still pictures. While running the sensor at full resolution all the time. This case too is better handled with dma-buf + GPU downscaling for the view-finder rather then all this custom special code. Besises this the ioctl expects a bunch of special non error checked conditions to be met otherwise things will crash/hang. The continues mode also involves a special cases all over the code getting in the way of further cleanups and simplifying the code to using just 1 /dev/video# node. So lets remove it and the related custom ATOMISP_IOC_S_CONT_CAPTURE_CONFIG ioctl.

Remove support for depth mode. This is a special mode where 2 streams (from 2 different sensors) can be setup and then starting/stopping 1 will automatically also start/stop the other. Like many of these special features I'm pretty sure that if the queue setup is not done exactly right things will crash and there is no error checking for this. This seems to be for stereoscopic vision and the only known hw which actually supports this is the Intel Aero board/SDK, all other 1000+ BYT/CHT models don't need this. This false outside of the standard webcam use scenario which we are trying to get working and this involves a bunch of hacks / special exceptions all over the code, so lets remove this.
