2022-08-19ipa: rkisp1: Add manual color gainsPaul Elder
Add support for manually controlling the color gains on the rkisp1 IPA. To that end, add and plumb the AwbEnable and ColourGains controls. As per-frame controls aren't supported yet in the rkisp1 IPA, simply apply and perform checks on the controls immediately.

2022-07-28ipa: rkisp1: Add support of ColorProcessing controlFlorian Sylvestre
Add ColorProcessing algorithm that is in charge to manage brightness, contrast and saturation controls. These controls are currently based on user controls.

2022-07-28ipa: rkisp1: Add support of Filter controlFlorian Sylvestre
Denoise and Sharpness filters will be applied by RkISP1 during the demosaicing step. The denoise filter is responsible for removing noise from the image, while the sharpness filter will enhance its acutance. Add filter algorithm with denoise and sharpness values based on user controls.

The Lens Shading Correction algorithm applies multipliers to all pixels to compensate for the lens shading effect. The coefficients are specified in a downscaled table in the YAML tuning file.

2022-03-28ipa: rkisp1: Introduce AWBJean-Michel Hautbois
The RkISP1 ISP calculates a mean value for Y, Cr and Cb at each frame. There is a RGB mode which could theoretically give us the values for R, G and B directly, but it seems to be failing right now. Convert those values into R, G and B and estimate the gain to apply in a grey world.

2022-03-28ipa: rkisp1: agc: Add a histogram-based gainJean-Michel Hautbois
As for the IPU3, we can estimate the histogram of the luminance. The RkISP1 can estimate multiple ones, the R, G and B ones, the Y only one and a combination of RGB. The one we are interested by in AGC is the Y histogram. Use the hardware revision to determine the number of bins of the produced histogram.

2022-03-28ipa: rkisp1: Use frame counter for the request queuedJean-Michel Hautbois
Introduce a frameCount variable in the IPAFrameContext which increments each time a request is queued. It is reset at configure call, when the camera is started. This will allow the frameCount to be used by other algorithms, without having to keep multiple private frame counters.

2021-11-29ipa: rkisp1: Introduce AGCJean-Michel Hautbois
Now that we have IPAContext and Algorithm, we can implement a simple AGC based on the IPU3 one. It is very similar, except that there is no histogram used for an inter quantile mean. The RkISP1 is returning a 5x5 array (for V10) of luminance means. Estimating the relative luminance is thus a simple mean of all the blocks already calculated by the ISP.

The ISP can use 25 or 81 cells depending on its revision. Remove the cached value in IPARkISP1 and use IPASessionConfiguration to store it and pass it to AGC later.

2021-11-29ipa: rkisp1: Introduce IPAContextJean-Michel Hautbois
Before using any algorithm, we want the IPAContext to be ready for those. Introduce the IPAContext following the existing design from IPA::IPU3. Each algorithm will then introduce the needed fields.
