The GNU Free Documentation License allows for a work to specify Invariant Sections that are not allowed to be modified. (Debian considers that this makes such works non-free.) The Linux Media Infrastructure userspace API documentation does not specify any such sections, but it also doesn't say there are none (as is recommended by the license text). Make it explicit that there are none. Signed-off-by:

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.

Part of the hardcoded initialization sequence is to set up the proper clock dividers. However, this is now done dynamically through proper code and as such, the static one is now redundant. Let's remove it. Signed-off-by:
-
Maxime Ripard authored
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 set_fmt operations updates the sensor format only when the image format is changed. When only the image sizes gets changed, the format do not get updated causing the sensor to always report the one that was previously in use.
