From 5f9e711b75a51b96c05f61a93b3f7c0d79dc20e2 Mon Sep 17 00:00:00 2001 From: Sakari Ailus Date: Wed, 2 May 2018 16:59:00 -0400 Subject: [PATCH] media: smiapp: Support the "rotation" property Use the "rotation" property to tell that the sensor is mounted upside down. This reverses the behaviour of the VFLIP and HFLIP controls as well as the pixel order.
