2017-07-25drm/radeon: Set depth on low mem to 16 bpp instead of 8 bppEgbert Eich
The radeon driver reduces the framebuffer resolution to 8bpp if a device with less than 32MB VRAM is found. This causes the framebuffer to run in 8 bit paletted mode. For a text console this is not an issue as 256 different colors is more than one gets on a VGA text console. However this leads to a poor 8bit pseudo-color visual when running X on fbdev, too, which is quite ugly. In this patch, we try to give some moderate compromise: limit the framebuffer bpp to 8 only when VRAM is 8MB or less, and use 16 bpp otherwise for 32MB or less VRAM.

2017-07-24drm/rockchip: fix Kconfig dependenciesArnd Bergmann
A bug that I had fixed earlier just came back, with CONFIG_EXTCON=m, the rockchip drm driver will fail to link: drivers/gpu/drm/rockchip/cdn-dp-core.o: In function `cdn_dp_get_port_lanes': cdn-dp-core.c:(.text.cdn_dp_get_port_lanes+0x30): undefined reference to `extcon_get_state' cdn-dp-core.c:(.text.cdn_dp_get_port_lanes+0x6c): undefined reference to `extcon_get_property' drivers/gpu/drm/rockchip/cdn-dp-core.o: In function `cdn_dp_check_sink_connection': cdn-dp-core.c:(.text.cdn_dp_check_sink_connection+0x80): undefined reference to `extcon_get_state' drivers/gpu/drm/rockchip/cdn-dp-core.o: In function `cdn_dp_enable': cdn-dp-core.c:(.text.cdn_dp_enable+0x748): undefined reference to `extcon_get_property' The problem is that that the sub-drivers are now all linked into the main rockchip drm module, which breaks all the Kconfig dependencies that are specified in the options for those sub-drivers. This clarifies the dependency to ensure that we can only turn on the DP driver when EXTCON is reachable. As the 'select' statements can now cause additional options to become built-in when they should be loadable modules, I'm moving those into the main driver config option. The dependency on DRM_ROCKCHIP can be reduced into a single 'if' statement here for brevity, but this has no functional effect.

This reverts commit 560a758d39c616f83ac25ff6e0816a49ebe6401c. The DPCD backlight commits regress a Thinkpad X1 Carbon 4th Gen and a BXT-P (in CI). Enabling dynamic backlight boots to a black screen, and enabling DPCD backlight leads to a black screen after suspend/resume.

2017-07-20drm/i915: Drop unpin stall in atomic_prepare_commitDaniel Vetter
The core already does this in setup_commit(). With this we can also remove the unpin_work_count since it's the last user, and also remove the loop since that was only used for stalling against legacy flips. v2: Amend commit message a bit (Chris).

2017-07-20drm/i915: Remove intel_flip_work infrastructureDaniel Vetter
This gets rid of all the interactions between the legacy flip code and the modeset code. Yay! This highlights an ommission in the atomic paths, where we fail to apply a boost to the pending rendering when we miss the target vblank. But the existing code is still dead and can be removed. v2: Note that the boosting doesn't work in atomic (Chris).

2017-07-20drm/i915: Rip out legacy page_flip completion/irq handlingDaniel Vetter
All these races and things are now solved through the vblank evasion trick, plus event handling is done using normal vblank even processing and drm_crtc_arm_vblank_event. We can get rid of all this complexity.
