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 Signed-off-by: Dave Airlie <airlied@redhat.com> From: Maxime Ripard <maxime.ripard@bootlin.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190808121423.xzpedzkpyecvsiy4@flea
