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.

Add new ioctls to set and get subdev client capabilities. Client in this context means the userspace application which opens the subdev device node. The client capabilities are stored in the file handle of the opened subdev device node, and the client must set the capabilities for each opened subdev. For now we only add a single flag, V4L2_SUBDEV_CLIENT_CAP_STREAMS, which indicates that the client is streams-aware. The reason for needing such a flag is as follows: Many structs passed via ioctls, e.g. struct v4l2_subdev_format, contain reserved fields (usually a single array field). These reserved fields can be used to extend the ioctl. The userspace is required to zero the reserved fields. We recently added a new 'stream' field to many of these structs, and the space for the field was taken from these reserved arrays. The assumption was that these new 'stream' fields are always initialized to zero if the userspace does not use them. This was a mistake, as, as mentioned above, the userspace is required to zero the _reserved_ fields. In other words, there is no requirement to zero this new stream field, and if the userspace doesn't use the field (which is the case for all userspace applications at the moment), the field may contain random data. This shows that the way the reserved fields are defined in v4l2 is, in my opinion, somewhat broken, but there is nothing to do about that. To fix this issue we need a way for the userspace to tell the kernel that the userspace has indeed set the 'stream' field, and it's fine for the kernel to access it. This is achieved with the new ioctl, which the userspace should usually use right after opening the subdev device node. Signed-off-by:
