OMAP display subsystem changes for 3.11 (part 1/2)
This is the first part of OMAP DSS changes for 3.11. This part contains fixes, cleanups and reorganizations that are not directly related to the new DSS device model that is added in part 2, although many of the reorganizations are made to make the part 2 possible. There should not be any functional changes visible to the user except the few bug fixes. The main new internal features: - Display (dis)connect support, which allows us to explicitly (dis)connect a whole display pipeline - Panel list, which allows us to operate without the specific DSS bus - Combine omap_dss_output to omap_dss_device, so that we have one generic "entity" for display pipeline blocks -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIcBAABAgAGBQJRvw+OAAoJEPo9qoy8lh71tygP/1NFil82hCslZeO3+jzEFhHq 0g16FuUtBeYtFnt6+bRcpMAEmoCrDQQBBQTNWloTQPxW6G3qmkxnKm+uKO9BPmfm uz7Fo37qrYQqu4oa/CoWEvgPlHjcfvjL5/NGGwGiiQNYNrjNLLMf5vKp3UhuqKFn N6CdPWoI8TuBtiFUYzbb2DYjcO60Ky8Gqr+/Lms9wjILFVXbav7KmqyYPqdxtEVx Vy9uA50YHxeQ61Ib6/cnBmxxuycX4jI545zOAsexPYotFh9SjLxQoHMbcbWAkBqE UkUi+zQpVhE9t3hPd8GnEZPDPo3AEYE034zXxU6QjEWzftUQDl5gzyAEMQLOdGyi 5x2Q4n7bsQG0vEXje4ko3o5VuPXzEmptgnm0J3pMpnMiJlZwBWtQHm1Tw7fOgv17 vvzMd9ojbLZVUa+ywWWR4Xb/4XH7PkLPSgk1x+MCcJ+6f2m/S/5ddqI6u+xd9CWH eaw5R4z6izG84bASaI7iEIZBhbP+TcUd+kNT3bqD4dQVp4ACJimb5P8DBSoP8yZL ViHhBcPixHrXxzucyV0PucYcvaiTG0HD4GMxFQQ1zabS4dqEG3Us3W5zNWzkAhf8 TeGcYi03gt+R6CL+GuzP9q1SkX3uYEETm57IFmSIpzxlZFW5pRVXj9F0CiscwbgM RuIzyzFoHG7w3dLIwh52 =I6Y2 -----END PGP SIGNATURE----- Merge tag 'omapdss-for-3.11-1' of git://gitorious.org/linux-omap-dss2/linux into fbdev/for-next OMAP display subsystem changes for 3.11 (part 1/2) This is the first part of OMAP DSS changes for 3.11.
