From 23aefee3378afc71a98b6c5a9e07e60591fec344 Mon Sep 17 00:00:00 2001 From: Nick Hollinghurst Date: Mon, 23 Jan 2023 15:49:26 +0000 Subject: ipa: raspberrypi: Add autofocus algorithm interface headers Add a new AfAlgorithm class that defines the interface for the Raspberry Pi autofocus algorithm. Add an AfStatus structure that returns the results of the autofocus algorithm back to the IPA. Add a structure for PDAF statistics provided by supported sensors for use with an autofocus algorithm. This structure is currently based on the IMX708's PDAF "Type 1" statistics.
