[libcamera-devel] [PATCH v3 1/3] ipa: rkisp1: Add enable field for AWB algorithm in IPA context

[Laurent Pinchart]

From: Florian Sylvestre <fsylvestre at baylibre.com>

Add an enable variable in the awb struct in IPASessionConfiguration which
indicates if the awb algorithm has been configured. This will allow other
algorithms to retrieve this information.
