[PATCH 0/2] Add Amlogic C3 ISP pipeline handler and IPA

[Keke Li]

The Amlogic C3 platform integrates an ISP capable of supporting
multi-camera, multi-exposure high dynamic range (HDR) imaging with up to
14-bit raw RGB Bayer data.

The C3 ISP pipeline handler supports 3-channel image output,
1-channel 3A statistics ouput and 1-channel parameters input.

The C3 ISP IPA is used to process 3A statistics and generate
parameters for ISP hardware. This IPA contains agc, awb, blc, ccm, csc
and post_gamma algorithms.
