[RFC PATCH 00/11] Improve linear algebra helpers in libipa

[Laurent Pinchart]

Hello,

This patch series tries to simplify IPA linear algebra calculations by
improving the Vector class API. The first 9 patches improves the Vector
class, and the last two patches showcase the improvements this can bring
in the rkisp1 AWB algorithm.

I'm relatively happy with the result. The only part I'm not sure about
is the introduction of the RGB type alias.

Laurent Pinchart (11):
  ipa: libipa: vector: Add mutable x(), y() and z() accessors
  ipa: libipa: vector: Add r(), g() and b() accessors
  ipa: libipa: vector: Add copy constructor and assignment operator
  ipa: libipa: vector: Rename the dot product operator*() to dot()
  ipa: libipa: vector: Generalize arithmetic operators
  ipa: libipa: vector: Add missing binary arithemtic operators
  ipa: libipa: vector: Add compound assignment operators
  ipa: libipa: vector: Add element-wise min() and max() functions
  ipa: libipa: vector: Add sum() and normalize() functions
  ipa: rkisp1: awb: Use RGB class to store colour gains
  ipa: rkisp1: awb: Replace manual calculations with Vector and Matrix
