2019-10-01drm/tiny: Kconfig: Remove always-y THERMAL dep. from TINYDRM_REPAPERUlf Magnusson
Commit 554b3529fe01 ("thermal/drivers/core: Remove the module Kconfig's option") changed the type of THERMAL from tristate to bool, so THERMAL || !THERMAL is now always y. Remove the redundant dependency. Discovered through Kconfiglib detecting a dependency loop. The C tools simplify the expression to y before running dependency loop detection, and so don't see it. Changing the type of THERMAL back to tristate makes the C tools detect the same loop. Not sure if running dep. loop detection after simplification can be called a bug. Fixing this nit unbreaks Kconfiglib on the kernel at least.

2019-09-27drm/komeda: SW workaround for D71 doesn't flush shadow registersLowry Li (Arm Technology China)
This is a SW workaround for shadow un-flushed when together with the DOU Timing-disable. D71 HW doesn't update shadow registers when display output is turned off. So when we disable all pipeline components together with display output disabling by one flush or one operation, the disable operation updated registers will not be flushed or valid in HW, which may lead problem. To workaround this problem, introduce a two phase disable for pipeline disable. Phase1: Disable components with display is on and flush it, this phase for flushing or validating the shadow registers. Phase2: Turn-off display output.

2019-09-27drm/vram: Support top-down placement flagThomas Zimmermann
Pinning lots of small buffer objects, such as cursors or sprites, to video memory can lead to fragmentation, which is a problem for devices with only a small amount of memory. As a result, framebuffer images might not get pinned, even though there's enough space available overall. The flag DRM_GEM_VRAM_PL_FLAG_TOPDOWN marks buffer objects to be pinned at the high end of video memory. This leaves contiguous space available at the memory's low end.

2019-09-25drm/dp_mst: Rename drm_dp_add_port and drm_dp_update_portLyude Paul
The names for these functions are rather confusing. drm_dp_add_port() sounds like a function that would simply create a port and add it to a topology, and do nothing more. Similarly, drm_dp_update_port() would be assumed to be the function that should be used to update port information after initial creation. While those assumptions are currently correct in how these functions are used, a quick glance at drm_dp_add_port() reveals that drm_dp_add_port() can also update the information on a port, and seems explicitly designed to do so. This can be explained pretty simply by the fact that there's more situations that would involve updating the port information based on a link address response as opposed to a connection status notification than the driver's initial topology probe. Case in point: reprobing link addresses after suspend/resume. Since we're about to start using drm_dp_add_port() differently for suspend/resume reprobing, let's rename both functions to clarify what they actually do.

2019-09-13drm: bridge/dw_hdmi: add audio sample channel status settingYakir Yang
When transmitting IEC60985 linear PCM audio, we configure the Aduio Sample Channel Status information in the IEC60958 frame. The status bit is already available in iec.status of hdmi_codec_params. This fix the issue that audio does not come out on some monitors (e.g. LG 22CV241) Note that these registers are only for interfaces: I2S audio interface, General Purpose Audio (GPA), or AHB audio DMA (AHBAUDDMA). For S/PDIF interface this information comes from the stream. Currently this function dw_hdmi_set_channel_status is only called from dw-hdmi-i2s-audio in I2S setup.
