Subject: [PATCH v2 19/30] media: atmel: atmel-isc: add CC initialization function
Date: Mon, 5 Apr 2021 18:50:54 +0300 [thread overview]
Message-ID: <20210405155105.162529-20-eugen.hristev@microchip.com> (raw)
In-Reply-To: <20210405155105.162529-1-eugen.hristev@microchip.com>
Implement the color correction (CC) submodule initialization, as a product
specific function, which currently configures the neutral point in color
correction.
