Merge tag 'drm-misc-next-2019-08-08' of git://anongit.freedesktop.org/drm/drm-misc into drm-next
drm-misc-next for 5.4:
UAPI Changes:
- HDCP: Add a Content protection type property
Cross-subsystem Changes:
Core Changes:
- Continue to rework the include dependencies
- fb: Remove the unused drm_gem_fbdev_fb_create function
- drm-dp-helper: Make the link rate calculation more tolerant to
non-explicitly defined, yet supported, rates
- fb-helper: Map DRM client buffer only when required, and instanciate a
shadow buffer when the device has a dirty function or says so
- connector: Add a helper to link the DDC adapter used by that connector to
the userspace
- vblank: Switch from DRM_WAIT_ON to wait_event_interruptible_timeout
- dma-buf: Fix a stack corruption
- ttm: Embed a drm_gem_object struct to make ttm_buffer_object a
superclass of GEM, and convert drivers to use it.
- hdcp: Improvements to report the content protection type to the
userspace
Driver Changes:
- Remove drm_gem_prime_import/export from being defined in the drivers
- Drop DRM_AUTH usage from drivers
- Continue to drop drmP.h
- Convert drivers to the connector ddc helper
- ingenic: Add support for more panel-related cases
- komeda: Support for dual-link
- lima: Reduce logging
- mpag200: Fix the cursor support
- panfrost: Export GPU features register to userspace through an ioctl
- pl111: Remove the CLD pads wiring support from the DT
- rockchip: Rework to use DRM PSR helpers, fix a bug in the VOP_WIN_GET
macro
- sun4i: Improve support for color encoding and range
- tinydrm: Rework SPI support, improve MIPI-DBI support, move to drm/tiny
- vkms: Rework of the CRC tracking
- bridges:
- sii902x: Add support for audio graph card
- tc358767: Rework AUX data handling code
- ti-sn65dsi86: Add Debugfs and proper DSI mode flags support
- panels
- Support for GiantPlus GPM940B0, Sharp LQ070Y3DG3B, Ortustech
COM37H3M, Novatek NT39016, Sharp LS020B1DD01D, Raydium RM67191,
Boe Himax8279d, Sharp LD-D5116Z01B
- Conversion of the device tree bindings to the YAML description
- jh057n00900: Rework the enable / disable path
- fbdev:
- ssd1307fb: Support more devices based on that controller
