From d87cdb884486bfa795be99c83a5b3ac4d428ca84 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Sun, 6 Sep 2015 10:59:08 -0300 Subject: [media] media-device: export the entity function via new ioctl Now that entities have a main function, expose it via MEDIA_IOC_G_TOPOLOGY ioctl. Please notice that some entities may have secundary functions. Such use case will be addressed later, when we add support for the Media Controller properties.
