From 12ffe28e1c6d43bd2a4e4bc15d36821d78f42e74 Mon Sep 17 00:00:00 2001 From: Naushir Patuck Date: Mon, 4 Dec 2023 16:19:00 +0000 Subject: build: controls: Add Raspberry Pi vendor specific controls Add a new control_ids_rpi.yaml file to hold the Raspberry Pi specific vendor controls. Define a control StatsOutputEnable to allow the ISP hardware statistics to be output through metadata via the Bcm2835StatsOutput control. The implementation of these controls will follow in a subsequent patch.
