[00/11] ipa: libipa: Introduce libipa algorithms

26877 mbox series

This series introduces the first algorithms in libipa: Awb, Lsc and Ccm.

As most of the implementations of the common algorithms derive from
RkISP1 it wasn't possible to separate the algorithm introduction with
the RkISP1 IPA modifications to maintain bisectability.

This series contains:

- Awb (Grey and Bayes)
 - RkISP1
 - Simple
 - Mali-C55

- Ccm
 - RkISP1
 - Simple
 - Mali-C55

- Lsc (grid and polynomial)
 - RkISP1
 - Mali-C55

Tested on RkISP1 with imx219 (Grey world awb and grid-based LSC) and on
Mali-C55 with imx708 (Bayes AWB and grid-based LSC).

More test on Simple and with polynomial LSC would be helpful :)
