Before we process the final unbind on an object and move it to the unbound list, it is semantically cleaner if there are no more active references to the object. (An active reference would imply that it was still being accessed by the GPU after it became inaccessible.) The caveat is that all callsites must be prepared for the object to disappeared during the unbind - i.e. they must hold their own reference. Signed-off-by:

Due to the lazy retirement semantics, even though we have unbound an object, it may still hold onto an active reference. So in the debug code, play safe. v2: Export i915_gem_shrink() rather than opencoding it. Signed-off-by:

eDP panels are generally designed to support only a single clock and lane configuration. commit 56071a20 Author: Jani Nikula <jani.nikula@intel.com> Date: Tue May 6 14:56:52 2014 +0300 drm/i915: use lane count and link rate from VBT as minimums for eDP should have started using the optimal link parameters for eDP panels. Turns out a certain other OS uses DPCD instead of VBT, which means trusting VBT on this may not be so reliable after all. Follow suit.

Oops, apparently intel_hdmi/intel_dp is the encoder - an object with a distinct lifetime to the connector, and so we cannot simply reuse the common function to unset and free the edid. Signed-off-by:

830 is very unhappy of the watermark value is too low (indicating a very high watermark in fact, ie. memory fetch will occur with an almost full FIFO). Limit the watermark value to at least 8 cache lines. That also matches the burst size we use on most platforms. BSpec seems to indicate we should limit the watermark to 'burst size + 1'. But on gen4 we already use a hardcoded 8 as the watermark value (as the spec says we should), so just use 8 as the limit on gen2/3 as well. Signed-off-by:

The spec says: "For the correct operation of the muxed DVO pins (GDEVSELB/ I2Cdata, GIRDBY/I2CClk) and (GFRAMEB/DVI_Data, GTRDYB/DVI_Clk): Bit 31 (DPLL VCO Enable) and Bit 30 (2X Clock Enable) must be set to “1” in both the DPLL A Control Register (06014h-06017h) and DPLL B Control Register (06018h-0601Bh)." The pipe A and B force quirks take care of DPLL_VCO_ENABLE, so we just need a bit of special care to handle DPLL_DVO_2X_MODE. v2: Recompute num_dvo_pipes on the spot, use PIPE_A/PIPE_B instead of pipe/!pipe for the register offsets in disable (Daniel) Add a comment about the ordering in enable and another one about filtering out the DVO 2x bit in state readout Signed-off-by:

Commit "drm/rcar-du: Use struct videomode in platform data" touches board code in arch/arm/mach-shmobile. There is, to the best of my knowledge, no risk of conflict for v3.18. Simon, are you fine with getting those changes merged through Dave's tree (and could you confirm that no conflict should occur) ? Simon acked the merge: Acked-by:

While zone->name is currently hard coded, the call to kobject_init_and_add() should follow the more defensive argument list usage (as already done in other places in ttm_memory.c) where "%s" is used instead of directly passing in a variable as a format string. Signed-off-by:

In order to support the "enable GPIO" available in many panel devices, this commit adds a proper devicetree binding. By providing an enable GPIO in the devicetree, the driver can now turn off and on the panel device, and/or the backlight device. Both the backlight and the GPIO are optional properties. Tested-by:

Instead of setting an initial value for the return code, set it explicitly on each error path. This is just a cosmetic cleanup, as preparation for the enable GPIO support. Tested-by:

The current backlight support is broken; the driver expects a backlight-class in the panel devicetree node. Fix this by implementing it properly, getting an optional backlight from a phandle. This shouldn't cause any backward-compatibility DT issue because the current implementation doesn't work and is not even documented. Tested-by:

The current error path calls tilcdc_unload() in case of an error to release the resources. However, this is wrong because not all resources have been allocated by the time an error occurs in tilcdc_load(). To fix it, this commit adds proper labels to bail out at the different stages in the load function, and release only the resources actually allocated. Tested-by:
