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
