From 9824d3a7d73beb4cb0f1711a5bd57ab181267868 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ond=C5=99ej=20Jirman?= Date: Sun, 26 Jan 2020 00:19:40 +0100 Subject: [PATCH 049/389] media: ov5640: Sleep after poweroff to ensure next poweron is not too early It's easy to use v4l2 userspace api in such a way that user can trigger a brownout on the sensor instead of a proper powerdown and powerup.
