From f479cf37ccda2be7204a964fe2747dfcb4b56bf6 Mon Sep 17 00:00:00 2001 From: Jacopo Mondi Date: Wed, 29 Apr 2020 11:50:38 +0200 Subject: [PATCH] media: i2c: imx219: Implement get_selection Implement the get_selection pad operation for the IMX219 sensor driver. The supported targets report the sensor's native size, the crop default rectangle and the crop rectangle.
