Merge tag 'media/v5.17-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media updates from Mauro Carvalho Chehab:

 - New sensor driver: ov5693

 - A new driver for STM32 Chrom-ART Accelerator

 - Added V4L2 core helper functions for VP9 codec

 - Hantro driver has gained support for VP9 codecs

 - Added support for Maxim MAX96712 Quad GMSL2 Deserializer

 - The staging atomisp driver has gained lots of improvements, fixes and
   cleanups. It now works with userptr

 - Lots of random driver improvements as usual

+For both Cherrytrail (CHT) and Baytrail (BHT) the driver

+
+- for BHT: /lib/firmware/shisp_2400b0_v21.bin

+
 NOTE:
 =====
 
-While the driver probes the hardware and reports itself as a
-V4L2 driver, there are still some issues preventing it to
-stream (at least it doesn't with the standard V4L2 applications.
-Didn't test yet with some custom-made app for this driver).
-Solving the related bugs and issues preventing it to work is
-needed (items 6 and 7 from the list below).
+This driver currently doesn't work with most V4L2 applications,
+as there are still some issues with regards to implementing
+certain APIs at the standard way.
+
+Also, currently only USERPTR streaming mode is working.
+
+In order to test, it is needed to know what's the sensor's
+resolution. This can be checked with:
+
+$ v4l2-ctl --get-fmt-video
+  Format Video Capture:
+	Width/Height      : 1600/1200
+	...
+
+It is known to work with:
+
+- v4l2grab at contrib/test directory at https://git.linuxtv.org/v4l-utils.git/
+
+  The resolution should not be bigger than the max resolution
+  supported by the sensor, or it will fail. So, if the sensor
+  reports:
+
+  The driver can be tested with:
+
+  v4l2grab -f YUYV -x 1600 -y 1200 -d /dev/video2 -u
+
+- NVT at https://github.com/intel/nvt
+
+  $ ./v4l2n -o testimage_@.raw \
+		 --device /dev/video2 \
+		 --input 0 \
+		 --exposure=30000,30000,30000,30000 \
+		 --parm type=1,capturemode=CI_MODE_PREVIEW \
+		 --fmt type=1,width=1600,height=1200,pixelformat=YUYV \

+		 --parameters=wb_config.r=32768,wb_config.gr=21043,wb_config.gb=21043,wb_config.b=30863 \
+		 --capture=20
+
+  As the output is in raw format, images need to be converted with:
+
+  $ for i in $(seq 0 19); do
+	name="testimage_$(printf "%03i" $i)"
+	./raw2pnm -x$WIDTH -y$HEIGHT -f$FORMAT $name.raw $name.pnm

-1. The atomisp doesn't rely at the usual i2c stuff to discover the
-   sensors. Instead, it calls a function from atomisp_gmin_platform.c.
-   There are some hacks added there for it to wait for sensors to be
-   probed (with a timeout of 2 seconds or so).
-   This should be converted to the usual way, using V4L2 async subdev
-   framework to wait for cameras to be probed;
+1.  Fix support for MMAP streaming mode. This is required for most
+    V4L2 applications;
 
-2. Use ACPI _DSM table - DONE!
+2.  Implement and/or fix V4L2 ioctls in order to allow a normal app to
+    use it;
 
-3. Switch the driver to use pm_runtime stuff. Right now, it probes the
-   existing PMIC code and sensors call it directly.
+3.  Ensure that the driver will pass v4l2-compliance tests;
 
-4. There's a problem at the sensor drivers: when trying to set a video
-   format, the atomisp main driver calls the sensor drivers with the
-   sensor turned off. This causes them to fail.
+4.  Get manufacturer's authorization to redistribute the binaries for
+    the firmware files;
 
-   The only exception is the atomisp-ov2880, which has a hack inside it
-   to turn it on when VIDIOC_S_FMT is called.
+5.  remove VIDEO_ATOMISP_ISP2401, making the driver to auto-detect the
+    register address differences between ISP2400 and ISP2401;
 
-   The right fix seems to power on the sensor when a video device is
-   opened (or at the first VIDIOC_ ioctl - except for VIDIOC_QUERYCAP),
-   powering it down at close() syscall.
+6.  Cleanup the driver code, removing the abstraction layers inside it;
 
-   Such kind of control would need to be done inside the atomisp driver,
-   not at the sensors code.

+8.  Switch to standard V4L2 sub-device API for sensor and lens. In
+    particular, the user space API needs to support V4L2 controls as
+    defined in the V4L2 spec and references to atomisp must be removed from
+    these drivers.
+
+9.  Use LED flash API for flash LED drivers such as LM3554 (which already
+    has a LED class driver).

+19. Correct Coding Style. Please refrain sending coding style patches
     for this driver until the other work is done, as there will be a lot
     of code churn until this driver becomes functional again.
 
-16. Fix private ioctls to not need a compat_ioctl handler for running
-    32-bit tasks. The compat code has been removed because of bugs,
-    and should not be needed for modern drivers. Fixing this properly
-    unfortunately means an incompatible ABI change.
+20. Remove the logic which sets up pipelines inside it, moving it to
+    libcamera and implement MC support.
