The bulk of these changes are preparation work and addition of support for Tegra186. Currently only HDMI output (the primary output on Jetson TX2) is supported, but the hardware is also capable of doing DSI and DisplayPort. Tegra DRM now also uses the atomic commit helpers instead of the open- coded variant that was only doing half its job. As a bit of a byproduct of the Tegra186 support the driver also gained HDMI 2.0 as well as zpos property support. Along the way there are also a few patches to clean up a few things and fix minor issues. -----BEGIN PGP SIGNATURE----- iQJHBAABCAAxFiEEiOrDCAFJzPfAjcif3SOs138+s6EFAlpXlPQTHHRyZWRpbmdA bnZpZGlhLmNvbQAKCRDdI6zXfz6zoUFKD/4vXdkmMUkWjZM0xrdwsPi6DvQe3uBa tE4wchelVnNvLJfBnMVJyEPDiNLoq12pJ6Ol8LRX2f5ExnQUwIEd+RSQPgWSUP6+ bITqSAb9LnEEHMfYLXTHFoBSeqV9nGvpYcouupW5R4cdV4/T7k7x1/6QQg6Byoyx TULTcpCmMFX4FQGrqWHSrPrkw+MDWYiDmekYcrHmrgOtZUfG7DxdWtQpgs2lrstg m+FZADSVJ9CwuVgwAO4VTDIeKVHW54b5UPYseH1u/uaAoxVPC50XNJk3RLuSPVWg 8d6BpkUoqmWq8w5tmR+/zx0/WobyRAQYljdd1kWFnnn3slNOvVV6bnOSo9u3OatZ 1DGyaeQr9hXQ2CdSx2oImex2Kslb14yJPczFa6GQBfrfPOPKJk8eh1GIF6bWGtQa +hzWr1BDDd/q2x6jkIFMQel33Z8dNy1+22GcSYpuofuQeMqD4msccfhnTce1/Mhy h0+fQK2eFWDbtvSj6rao4CtzVDOCi9+b93Hva/kh7Ap2Wn7eUDLmRh/VtnUj7EP7 LYPNYlFC6rWzfTdHV0oYUizXNRx6ZzQFNYXNmRjjfVMzrXeqkpSsZXcYVhd4J3PB EmZpiWNeqqGUnoxvSUX0AmC3/VSi7dU+E8ecIzyeVMry2cgXSal7gewPirDUICOI uiYCJaeWxHJBAA== =FfXI -----END PGP SIGNATURE----- Merge tag 'drm/tegra/for-4.16-rc1-fixes' of git://anongit.freedesktop.org/tegra/linux into drm-next drm/tegra: Changes for v4.16-rc1 The bulk of these changes are preparation work and addition of support for Tegra186.
