From ee10dc36b485920e87eefa325d74fd8804648621 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Thu, 4 Oct 2018 17:06:32 -0400 Subject: [PATCH] media: cropcap/g_selection split If g_selection is implemented, then the v4l2-ioctl cropcap code assumes that cropcap just implements the pixelaspect part and that g_selection provides the crop bounds and default rectangles. There are still some drivers that only implement cropcap and not g_selection. Split up cropcap into a cropcap and g_selection for those drivers.
