The clock rate, while hardcoded until now, is actually a function of the resolution, framerate and bytes per pixel. Now that we have an algorithm to adjust our clock rate, we can select it dynamically when we change the mode. This changes a bit the clock rate being used, with the following effect: +------+------+------+------+-----+-----------------+----------------+-----------+ | Hact | Vact | Htot | Vtot | FPS | Hardcoded clock | Computed clock | Deviation | +------+------+------+------+-----+-----------------+----------------+-----------+ | 640 | 480 | 1896 | 1080 | 15 | 56000000 | 61430400 | 8.84 % | | 640 | 480 | 1896 | 1080 | 30 | 112000000 | 122860800 | 8.84 % | | 1024 | 768 | 1896 | 1080 | 15 | 56000000 | 61430400 | 8.84 % | | 1024 | 768 | 1896 | 1080 | 30 | 112000000 | 122860800 | 8.84 % | | 320 | 240 | 1896 | 984 | 15 | 56000000 | 55969920 | 0.05 % | | 320 | 240 | 1896 | 984 | 30 | 112000000 | 111939840 | 0.05 % | | 176 | 144 | 1896 | 984 | 15 | 56000000 | 55969920 | 0.05 % | | 176 | 144 | 1896 | 984 | 30 | 112000000 | 111939840 | 0.05 % | | 720 | 480 | 1896 | 984 | 15 | 56000000 | 55969920 | 0.05 % | | 720 | 480 | 1896 | 984 | 30 | 112000000 | 111939840 | 0.05 % | | 720 | 576 | 1896 | 984 | 15 | 56000000 | 55969920 | 0.05 % | | 720 | 576 | 1896 | 984 | 30 | 112000000 | 111939840 | 0.05 % | | 1280 | 720 | 1892 | 740 | 15 | 42000000 | 42002400 | 0.01 % | | 1280 | 720 | 1892 | 740 | 30 | 84000000 | 84004800 | 0.01 % | | 1920 | 1080 | 2500 | 1120 | 15 | 84000000 | 84000000 | 0.00 % | | 1920 | 1080 | 2500 | 1120 | 30 | 168000000 | 168000000 | 0.00 % | | 2592 | 1944 | 2844 | 1944 | 15 | 84000000 | 165862080 | 49.36 % | +------+------+------+------+-----+-----------------+----------------+-----------+ Only the 640x480, 1024x768 and 2592x1944 modes are significantly affected by the new formula. In this case, 640x480 and 1024x768 are actually fixed by this change. Indeed, the sensor was sending data at, for example, 27.33fps instead of 30fps. This is -9%, which is roughly what we're seeing in the array. Testing these modes with the new clock setup actually fix that error, and data are now sent at around 30fps. 2592x1944, on the other hand, is probably due to the fact that this mode can only be used using MIPI-CSI2, in a two lane mode, and never really tested with a DVP bus.

2018-12-05media: ov5640: Adjust the clock based on the expected rateMaxime Ripard1-1/+364
The clock structure for the PCLK is quite obscure in the documentation, and was hardcoded through the bytes array of each and every mode. This is troublesome, since we cannot adjust it at runtime based on other parameters (such as the number of bytes per pixel), and we can't support either framerates that have not been used by the various vendors, since we don't have the needed initialization sequence. We can however understand how the clock tree works, and then implement some functions to derive the various parameters from a given rate. And now that those parameters are calculated at runtime, we can remove them from the initialization sequence. The modes also gained a new parameter which is the clock that they are running at, from the register writes they were doing, so for now the switch to the new algorithm should be transparent.

The v4l2_dv_timings_cap struct is used to do sanity checks when setting and enumerating DV timings, ensuring that only valid timings as per the HW capabilities are allowed. However, many drivers just filled in 0 for the minimum width, height or pixelclock frequency. This can cause timings with e.g. 0 as width and height to be accepted, which will in turn lead to a potential division by zero. Fill in proper values are minimum boundaries. 640x350 was chosen since it is the smallest resolution in v4l2-dv-timings.h. Same for 13 MHz as the lowest pixelclock frequency (it's slightly below the minimum of 13.5 MHz in the v4l2-dv-timings.h header).

Swapping the order between v4l2 subdevice registration and checking chip id in b7a417628abf ("media: ov2680: don't register the v4l2 subdevice before checking chip ID") makes the mode restore to use the sensor controls before they are set, so move the mode restore call to s_power after the handler setup for controls is done. This remove also the need for the error code path in power on function.

2018-11-23media: video-i2c: avoid accessing released memory area when removing driverAkinobu Mita1-5/+6
The video device release() callback for video-i2c driver frees the whole struct video_i2c_data. If there is no user left for the video device when video_unregister_device() is called, the release callback is executed. However, in video_i2c_remove() some fields (v4l2_dev, lock, and queue_lock) in struct video_i2c_data are still accessed after video_unregister_device() is called. This fixes the use after free by moving the code from video_i2c_remove() to the release() callback.
