drm/i915: move modesetting output/encoder code under display/

2019-06-17T08:25:06+00:00

Add a new subdirectory for display code, and start off by moving modesetting output/encoder code. Judging by the include changes, this is a surprisingly clean operation. v2: - move intel_sdvo_regs.h too - use tabs for Makefile file lists and sort them Cc: Chris Wilson Cc: Joonas Lahtinen Cc: Rodrigo Vivi Cc: Ville Syrjälä Reviewed-by: Chris Wilson Acked-by: Rodrigo Vivi Acked-by: Maarten Lankhorst Acked-by: Ville Syrjälä Signed-off-by: Jani Nikula Link: https://patchwork.freedesktop.org/patch/msgid/20190613084416.6794-2-jani.nikula@intel.com

drm/i915: Rename SDVO_AUDIO_ENABLE to HDMI_AUDIO_ENABLE

2019-06-07T17:39:12+00:00

The "audio enable" bit on the SDVO/HDMI control register is only meant for HDMI. Audio is never delivered over the SDVO bus. Rename the define to reflect this fact.

drm/i915: add i2c symlink under hdmi connector

2019-06-04T13:42:53+00:00

Currently, the i2c adapter is available only under DP connectors. Add i2c symlink under hdmi connector pointing to i2c adapter in order to make this behaviour consistent. The initial motivation was to make igt i2c subtest patch [1] work on all connectors.

Pull drm updates from Dave Airlie: "This has two exciting community drivers for ARM Mali accelerators. Since ARM has never been open source friendly on the GPU side of the house, the community has had to create open source drivers for the Mali GPUs. Lima covers the older t4xx and panfrost the newer 6xx/7xx series. Well done to all involved and hopefully this will help ARM head in the right direction. There is also now the ability if you don't have any of the legacy drivers enabled (pre-KMS) to remove all the pre-KMS support code from the core drm, this saves 10% or so in codesize on my machine. i915 also enable Icelake/Elkhart Lake Gen11 GPUs by default, vboxvideo moves out of staging. There are also some rcar-du patches which crossover with media tree but all should be acked by Mauro.
