git://anongit.freedesktop.org/drm-intel into drm-next Since your main drm-next pull isn't out of the door yet I figured I might as well flush out drm-misc instead of delaying for 4.6.

2016-01-11apple-gmux: Add initial documentationLukas Wunner
Document what I've learned so far about the gmux so that we can collaboratively reverse-engineer its remaining unknown bits without everyone having to start from scratch. The DOC sections are bound together in the gpu.tmpl DocBook under a new vga_switcheroo "Handlers" chapter. Eventually this should be amended with documentation about the four other handlers that exist so far (nouveau v1 DSM, nouveau Optimus DSM, radeon ATPX, amdgpu ATPX). Requires kernel-doc with asciidoc support. The EFI variable was reverse-engineered by Bruno Bierbaumer <bruno@bierbaumer.net> and Andreas Heider <andreas@meetr.de>. Some of the remaining open questions: * How are vblank intervals synchronized on retinas to achieve seamless switching? Is the DP mux capable of this? It's not mentioned in the data sheets. Or is it done at the OS level, i.e. do we have to synchronize vblank intervals between DRM drivers? There's a signal coming from the panel connector and going into gmux, could this be the vblank signal as received by the panel to properly time the switch? * On retinas there's an I2C bus between gmux and the connector of the right I/O board, apparently leading to the Parade PS8401A HDMI repeater. What is this for, is it controlled via gmux registers? Data sheet: http://www.paradetech.com/products/jitter-cleaning-repeaters/ps8401/ * On retinas there's an I2C bus between gmux and the LED driver. Pre-retinas connected the LED driver to SMBUS. Are there additional gmux registers on retinas to control it? * The MacPro6,1 2013 also has a gmux, the same Renesas R4F2113 as the retina MacBook Pro. The Mac Pro doesn't have a built-in display, so what is its purpose? Power control of the dual FirePro GPUs? Switching of the external DP/Thunderbolt ports? The iFixit teardown clearly shows one TI HD3SS212 DisplayPort mux on the logic board next to one of the three Thunderbolt controllers. However six muxes would be necessary to switch all six ports between GPUs. The mux is probably necessary for one of the display configurations allowed by Apple, but which one? https://www.ifixit.com/Teardown/Mac+Pro+Late+2013+Teardown/20778 https://d3nevzfk7ii3be.cloudfront.net/igi/fELBTnt31QhnDsqq.huge https://support.apple.com/en-us/HT202801 * Registers we haven't decoded yet: 0x700 32 Bit configmap? 0x708 32 Bit power sequence? 0x712 8 Bit status of clock from panel on retinas? 0x713 8 Bit dito? 0x724 16 Bit backlight, raw value? 0x760 32 Bit backlight 0x764 32 Bit backlight 0x768 8 Bit backlight 0x76a 16 Bit backlight 0x76c 16 Bit backlight 0x76e 16 Bit backlight 0x77f edp/dp/hdmi probe? retina only. * Addition by Bruno Prémont <bonbons@linux-vserver.org>: "Missing is also precise knowledge as to what the gmux depends on. From behavioral reports, it is somehow sensitive to VGA IO/MEM routing (it apparently needs the routing to go to integrated GPU, not discrete GPU). When the routing is inappropriate backlight control IO just reads back as 0xFF (and eventually gmux IO in general does so)."

Boris dug out Thierry's drm-trivial branch and resubmitted everything since that branch didn't really work out.

2015-12-08doc: dt: mtd: partitions: add compatible property to "partitions" nodeBrian Norris
As noted here [1], there are potentially future conflicts if we try to use MTD's "partitions" subnode to describe anything besides just the fixed-in-the-device-tree partitions currently described in this document. Particularly, there was a proposal to use this node for the AFS parser too. It can pose a (small) problem to try to differentiate the following nodes: // using binding as currently specified partitions { #address-cells = <x>; #size-cells = <y>; partition@0 { ...; }; }; and // proposed future binding partitions { compatible = "arm,arm-flash-structure"; }; It's especially difficult if other uses of this node start having subnodes. So, since the "partitions" node is new in v4.4, let's fixup the binding before release so that it requires a compatible property, so it's much clearer to distinguish. e.g.: // proposed partitions { compatible = "fixed-partitions"; #address-cells = <x>; #size-cells = <y>; partition@0 { ...; }; }; [1] Subject: "mtd: create a partition type device tree binding" http://lkml.kernel.org/g/20151113220039.GA74382@google.com http://lists.infradead.org/pipermail/linux-mtd/2015-November/063355.html http://lists.infradead.org/pipermail/linux-mtd/2015-November/063364.html Cc: Michal Suchanek <hramrach@gmail.com> Signed-off-by: Brian Norris <computersforpeace@gmail.com> Acked-by: Rob Herring <robh@kernel.org>
2015-12-08drm: document drm_crtc_funcsDaniel Vetter
And merge any docbook we have into the kerneldoc comments. Since it's a legacy entry point with only two implementation (one each in atomic and legacy crtc helpers) I've made the documentation for set_config fairly sparse - no one should ever need to look at this again, all the ABI we have is baked into code. For ->page_flip otoh I kept all the extensive docs from the docbook and even extended it where it was lacking: Currently we have a pile of legacy page_flip implemantations, and even for atomic drivers there's not yet a standard implementation in the helpers. Which means every driver needs to implement this itself, and precise specs are really valuable. Otherwise there's just cursor, which really just boils down to "use at least universal planes". And gamma tables (where we have a bit a mess with the fbdev helper gamma hooks). v2: Spelling fixes (Eric). v3: Suggestions from Thierry.

2015-12-08drm: Reorganize helper vtables and their docsDaniel Vetter
Currently we have 4 helper libraries (probe, crtc, plane & atomic) that all use the same helper vtables. And that's by necessity since we don't want to litter the core structs with one ops pointer per helper library. Also often the reuse the same hooks (like atomic does, to facilite conversion from existing drivers using crtc and plane helpers). Given all that it doesn't make sense to put the docs for these next to specific helpers. Instead extract them into a new header file and section in the docbook, and add references to them everywhere. Unfortunately kernel-doc complains when an include directive doesn't find anything (and it does by dumping crap into the output file). We have to remove the now empty includes to avoid that, instead of leaving them in for future proofing. v2: More OCD in ordering functions. v3: Spelling plus collate copyright headers properly.

The workaround for this issue is to bring up the interface first and then enable SR-IOV as this will trigger the reset in the existing code. I clean up legacy license stuff in the e100.txt documentation and then update the maintainers/reviewers list for our drivers. Jesse fixes an issue with the i40e/i40evf drivers, where if the driver were to happen to have a mutex held while the i40e_init_adminq() call was called, the init_adminq might inadvertently call mutex_init on a lock that was held which is a violation of the calling semantices. ==================== Signed-off-by: David S.

This patch enables setting custom TX IP checksum limit by adding new optional property to the mvneta device tree node.
