From 8cc3c2bf16ff54a2cc0fa8545841f616cae6f99a Mon Sep 17 00:00:00 2001 From: Pointer Kung Date: Wed, 8 May 2024 03:38:35 +0000 Subject: [PATCH] Enable PMU during photo capture This CL enables PMU feature during photo capture. With the new settings, we can achieve up to 120ms saving in capture latency, while paying a penalty of 60mW. However, even with the added power, we are still below the F10 numbers (go/f10-camera-power-gtw).
