UAPI Changes: - Commandline parser: Add support for panel orientation, and per-mode options. - Fix IOCTL naming for dma-buf heaps. Cross-subsystem Changes: - Rename DMA_HEAP_IOC_ALLOC to DMA_HEAP_IOCTL_ALLOC before it becomes abi. - Change DMA-BUF system-heap's name to system. - Fix leak in error handling in dma_heap_ioctl(), and make a symbol static. - Fix udma-buf cpu access. - Fix ti devicetree bindings. Core Changes: - Add CTA-861-G modes with VIC >= 193. - Change error handling and remove bug_on in *drm_dev_init. - Export drm_panel_of_backlight() correctly once more. - Add support for lvds decoders. - Convert drm/client and drm/(gem-,)fb-helper to drm-device based logging and update logging todo. Driver Changes: - Add support for dsi/px30 to rockchip. - Add fb damage support to virtio. - Use dma_resv locking wrappers in vc4, msm, etnaviv. - Make functions in virtio static, and perform some simplifications. - Add suspend support to sun4i. - Add A64 mipi dsi support to sun4i. - Add runtime pm suspend to komeda. - Associated driver fixes. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEuXvWqAysSYEJGuVH/lWMcqZwE8MFAl4N6t8ACgkQ/lWMcqZw E8P0ww/9EEa1W1nkaYmxfWCtmBV3D6QS4490jj62RMBXETezZmLPV11xpFqTPzcw 9vRwD7PwP+rIDPTnEcg8vIMnhDgZuUMGv93PZrFZMHxe4MHeykQ6BOj4pWEnrkr4 CQxC0exyIG8sQkH5+OngXkPnANPpzsegAAQ2rGbUf0HxxdZ1WeV3aqlQFo2YDpd9 c8ouYhgnIP4NfLPYnVN3NQs/hQIVJRJ9vOHr+o8k7Fn9YoFak7ry6UFsSAan4j7I ZQDQzPnT5CQBBSRTh9vQinOexj5bkW3AFyNFA7mknv05LHYb1kMPIIqnY01pbi2w SyWc5oqJwwdCFPCLZIUHZMOBKYqGKWP0KTjy7+QKx2ty+Sjgf3hTZwnVdtNVLFJe 7WsXP6Dg+PoSsSEGZuwGOzbr7GCJitSXhUs5GGiMbdbTPzr3rJsDLuyf9/Q1ObUC F+yIKkcwYZogeXRShFFQ3wjAxEQ83yyuTchyagvqSoqFsT5ccUjuUqInGAbYifPS QfhI1U9hQGmINqXPSkQYHXxMKg+Vl2KWvFknhmLIc0Cf3fRsu+wf3NAokrHsraxd RINvo2U5XDhPctRYXaPjPiYtPlnikR69mhyGcd7VG81F72ECzZr/2q1NmsEMmUac VqowhgoG8Tm4LcZHloMw4UlCtjV2esvztc2T6b95Mg6j1r4aav0= =ye8f -----END PGP SIGNATURE----- Merge tag 'drm-misc-next-2020-01-02' of git://anongit.freedesktop.org/drm/drm-misc into drm-next drm-misc-next for v5.6: UAPI Changes: - Commandline parser: Add support for panel orientation, and per-mode options. - Fix IOCTL naming for dma-buf heaps.
