From 3200bb635ccd64d5997bc372d9fa6bc894b2f9d0 Mon Sep 17 00:00:00 2001 From: Paul Elder Date: Thu, 18 Aug 2022 18:01:08 +0900 Subject: ipa: rkisp1: Add manual color gains 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.
