2018-11-07spi: gpio: Support 3WIRE high-impedance turn-aroundLinus Walleij
Some devices such as the TPO TPG110 display panel require a "high-impedance turn-around", in effect a clock cycle after switching the line from output to input mode. Support this in the GPIO driver to begin with. Other driver may implement it if they can, it is unclear if this can be achieved with anything else than GPIO bit-banging.

2018-11-07mm, drm/i915: mark pinned shmemfs pages as unevictableKuo-Hsin Yang
The i915 driver uses shmemfs to allocate backing storage for gem objects. These shmemfs pages can be pinned (increased ref count) by shmem_read_mapping_page_gfp(). When a lot of pages are pinned, vmscan wastes a lot of time scanning these pinned pages. In some extreme case, all pages in the inactive anon lru are pinned, and only the inactive anon lru is scanned due to inactive_ratio, the system cannot swap and invokes the oom-killer. Mark these pinned pages as unevictable to speed up vmscan. Export pagevec API check_move_unevictable_pages(). This patch was inspired by Chris Wilson's change [1].

2018-11-07usb: typec: tcpm: Do not disconnect link for self powered devicesBadhri Jagan Sridharan
During HARD_RESET the data link is disconnected. For self powered device, the spec is advising against doing that. >From USB_PD_R3_0 7.1.5 Response to Hard Resets Device operation during and after a Hard Reset is defined as follows: Self-powered devices Should Not disconnect from USB during a Hard Reset (see Section 9.1.2). Bus powered devices will disconnect from USB during a Hard Reset due to the loss of their power source. Tackle this by letting TCPM know whether the device is self or bus powered. This overcomes unnecessary port disconnections from hard reset. Also, speeds up the enumeration time when connected to Type-A ports.

The documentation for the .raw_event() callback says that if the driver return 1, there will be no further processing of the event, but this is not true, the actual code in hid-core.c looks like this: if (hdrv && hdrv->raw_event && hid_match_report(hid, report)) { ret = hdrv->raw_event(hid, report, data, size); if (ret < 0) goto unlock; } ret = hid_report_raw_event(hid, type, data, size, interrupt); The only return value that has any effect on the processing is a negative error.

2018-11-05drm/scheduler: Add drm_sched_job_cleanupSharat Masetty
This patch adds a new API to clean up the scheduler job resources. This is primarliy needed in cases the job was created but was not queued to the scheduler queue. Additionally with this change, the layer which creates the scheduler job also gets to free up the job's resources and this entails moving the dma_fence_put(finished_fence) to the drivers ops free handler routines.

2018-11-05drm/sched: Add boolean to mark if sched is ready to work v5Andrey Grodzovsky
Problem: A particular scheduler may become unsuable (underlying HW) after some event (e.g. GPU reset). If it's later chosen by the get free sched. policy a command will fail to be submitted. Fix: Add a driver specific callback to report the sched status so rq with bad sched can be avoided in favor of working one or none in which case job init will fail. v2: Switch from driver callback to flag in scheduler. v3: rebase v4: Remove ready paramter from drm_sched_init, set uncoditionally to true once init done. v5: fix missed change in v3d in v4 (Alex) Signed-off-by: Andrey Grodzovsky <andrey.grodzovsky@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2018-11-05drm/amdgpu: Add DCC flags for GFX9 amdgpu_boNicholas Kazlauskas
[Why] Hardware support for Delta Color Compression (DCC) decompression is available in DC for GFX9 but there's no way for userspace to enable the feature. Enabling the feature can provide improved GFX performance and power savings in many situations. [How] Extend the GFX9 tiling flags to include DCC parameters. These are logically grouped together with tiling flags even if they are technically distinct. This trivially maintains backwards compatibility with existing users of amdgpu_gem_metadata. No new IOCTls or data structures are needed to support DCC. This patch helps expose DCC attributes to both libdrm and amdgpu_dm.

2018-11-05drm/ttm: Provide ttm_bo_global_{init/release}() for struct ttm_bo_globalThomas Zimmermann
So far, struct ttm_bo_global_ref was the only way of initializing a struct ttm_bo_global. Providing separate initializer and release functions for struct ttm_bo_global gives drivers the option of implementing their own init and release callbacks for drm_global_references of type DRM_GLOBAL_TTM_BO. The original functions for initializing and releasing via struct ttm_bo_global_ref are wrappers around the new interfaces.
