git://anongit.freedesktop.org/drm-intel into drm-next Refcounting is hard, so here's a quick pull request with the one-liner to fix up i915. Otherwise just a few other small things I picked up. Plus the regression fix from Marten for rmfb behaviour that lingered around forever since no testers. Feel free to cherry-pick that over to drm-fixes, but given that there's not many who seemed to have cared, meh. * tag 'topic/drm-misc-2016-05-08' of git://anongit.freedesktop.org/drm-intel: drm/i915: Correctly refcount connectors in hw state readou drm/panel: Flesh out kerneldoc drm: Add gpu.tmpl docbook to MAINTAINERS entry drm/core: Do not preserve framebuffer on rmfb, v4. drm: Fix up markup fumble drm/fb_helper: Fix a few typos

2016-05-08drm/msm: Drop load/unload drm_driver opsArchit Taneja
The load/unload drm_driver ops are deprecated. They should be removed as they result in creation of devices visible to userspace even before the drm_device is registered. Drop these ops and use drm_dev_alloc/register and drm_dev_unregister/unref to explicitly create and destroy the drm device in the msm platform driver's bind and unbind ops. With this in use, the drm connectors are only registered once the drm_device is registered. It also fixes the issue of stray debugfs files after the msm module is removed. With this, all the debugfs files are removed, and allows successive module insertions/removals. Signed-off-by: Archit Taneja <architt@codeaurora.org>
2016-05-08drm/msm: Centralize connector registration/unregistrationArchit Taneja
Move the drm_connector registration from the encoder(HDMI/DSI etc) drivers to the msm platform driver. This will simplify the task of ensuring that the connectors are registered only after the drm_device itself is registered. The connectors' destroy ops are made to use kzalloc instead of devm_kzalloc to ensure that that the connectors can be successfully unregistered when the msm driver module is removed. The memory for the connectors is unallocated when drm_mode_config_cleanup() is called during either during an error or during driver remove.

2016-05-08drm/msm/hdmi: Prevent gpio_free related kernel warningsArchit Taneja
Calling the legacy gpio_free on an invalid GPIO (a GPIO numbered -1) results in kernel warnings. This causes a lot of backtraces when we try to unload the drm/msm module. Call gpio_free only on valid GPIOs. Signed-off-by: Archit Taneja <architt@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>

2016-05-08drm/msm/mdp4: Don't manage DSI PLL regulators in MDP driverArchit Taneja
The MDP4 driver tries to request and set voltages for regulators required by the DSI PLLs. Firstly, the MDP4 driver shouldn't manage the DSI regulators, this should be handled in the DSI driver. Secondly, it shouldn't try to set a fixed voltage for regulators. Voltage constraints should be specified on the regulator via DT and managed by the regulator core. Remove all the DSI PLL regulator related code from the MDP4 driver. It's managed in the DSI driver for MSM8960/APQ8064 already.

2016-05-08drm/msm/edp: Drop regulator_set_voltage callArchit Taneja
The eDP driver tries to set a fixed voltage for one of its regulators(vdda) before enabling it. This shouldn't be done by the driver, the voltage constraints should be specified on the regulator via DT and managed by the regulator core. A driver should call regulator_set_voltage only if it needs to change the voltage during runtime. Drop the regulator_set_voltage call. Mention in a comment the voltage that the regulator expects.

2016-05-08drm/msm/dsi: Fix regulator API abuseArchit Taneja
The voltage changing code in this driver is broken and should be removed. The driver sets a single, exact voltage on probe. Unless there is a very good reason for this (which should be documented in comments) constraints like this need to be set via the machine constraints, voltage setting in a driver is expected to be used in cases where the voltage varies at runtime. In addition client drivers should almost never be calling regulator_can_set_voltage(), if the device needs to set a voltage it needs to set the voltage and the regulator core will handle the case where the regulator is fixed voltage. If the driver simply skips setting the voltage if it doesn't have permission then it should just not bother in the first place. Originally authored by Mark Brown <broonie@kernel.org> Remove the min/max voltage data entries per SoC managed by the driver. These aren't needed as we don't try to set voltages any more. Mention in comments the voltages that each regulator expects. Signed-off-by: Archit Taneja <architt@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>
2016-05-08drm/msm: Move call to PTR_ERR_OR_ZERO after reassignmentVaishali Thakkar
Here, a location is reset to NULL before being passed to PTR_ERR. So, PTR_ERR should be called before its argument is reassigned to NULL.

2016-05-08drm/msm: fix ->last_fence() after recoverRob Clark
It is no longer true that we discard all in-flight submits on recover (these days we only discard the first one that hung). After the first re-submitted batch completes it would overwrite the fence with a correct value, but there would be a window of time which showed all re-submitted batches as already complete.

2016-05-08drm/msm: remove fence_cbsRob Clark
This was only used for atomic commit these days. So instead just give atomic it's own work-queue where we can do a block on each bo in turn. Simplifies things a whole bunch and makes the 'struct fence' conversion easier. Signed-off-by: Rob Clark <robdclark@gmail.com>
2016-05-08drm/msm: introduce msm_fence_contextRob Clark
Better encapsulate the per-timeline stuff into fence-context. For now there is just a single fence-context, but eventually we'll also have one per-CRTC to enable fully explicit fencing. Signed-off-by: Rob Clark <robdclark@gmail.com>
2016-05-08drm/msm: split locking and pinning BO'sRob Clark
Split up locking and pinning buffers in the submit path. This is needed because we'll want to insert fencing in between the two steps. This makes things end up looking more similar to etnaviv submit code (which was originally modelled on the msm code but has already added 'struct fence' support). Signed-off-by: Rob Clark <robdclark@gmail.com>
2016-05-08drm/msm/gpu: simplify tracking in-flight bo'sRob Clark
Since we already track the array of bo's in the submit object, just unconditionally take and drop ref's per submit (rather than only taking ref's if bo is not already active). This simplifies later patches. Signed-off-by: Rob Clark <robdclark@gmail.com>
