Pull drm updates from Dave Airlie: "This is the main git pull for the drm, I pretty much froze major pulls at -rc5/6 time, and haven't had much fallout, so will probably continue doing that.

2014-09-23imx-drm: imx-drm-core: add basic suspend/resume supportShawn Guo1-0/+33
HDMI currently stops working after a system suspend/resume cycle. The cause is that the mode setting states in hardware gets lost and isn't restored across the suspend/resume cycle. The patch adds a very basic suspend/resume support to imx-drm driver, and calls drm_helper_resume_force_mode() in .resume hook to restore the mode setting states, so that HDMI can continue working after a system suspend/resume cycle. Since the suspend/resume hook can be called with drm_device pointer being NULL from driver data, we need a check on the pointer in the hooks. And to avoid using a stale pointer from driver data, it also clears driver data in .unload hook.

2014-09-23imx-drm: ipuv3-plane: remove function ipu_plane_dpms()Shawn Guo1-25/+4
All those ipu_*_put() calls in ipu_plane_dpms() are unnecessary, because the only occurrence of ipu_plane_dpms() with 'mode' not being DRM_MODE_DPMS_ON is in function ipu_disable_plane(), which already has a ipu_plane_put_resources() call to put those ipu resources right after ipu_plane_dpms(). So with those redundant ipu_*_put() calls removed from ipu_plane_dpms(), the only left code in the function is ipu_plane_enable|disable(). Thus, we can just call ipu_plane_enable|disable() as needed directly and remove the ipu_plane_dpms() function completely.

2014-09-10drm: add driver->set_busid() callbackDavid Herrmann1-0/+1
One step closer to dropping all the drm_bus_* code: Add a driver->set_busid() callback and make all drivers use the generic helpers. Nouveau is the only driver that uses two different bus-types with the same drm_driver. This is totally broken if both buses are available on the same machine (unlikely, but lets be safe). Therefore, we create two different drivers for each platform during module_init() and set the set_busid() callback respectively.

Confusion ensues and things go pear shaped when one file is closed and there is no master anymore." Conflicts: drivers/gpu/drm/drm_drv.c drivers/gpu/drm/drm_stub.c
2014-08-05drm: drop redundant drm_file->is_masterDavid Herrmann1-1/+1
The drm_file->is_master field is redundant as it's equivalent to: drm_file->master && drm_file->master == drm_file->minor->master 1) "=>" Whenever we set drm_file->is_master, we also set: drm_file->minor->master = drm_file->master; Whenever we clear drm_file->is_master, we also call: drm_master_put(&drm_file->minor->master); which implicitly clears it to NULL. 2) "<=" minor->master cannot be set if it is non-NULL. Therefore, it stays as is unless a file drops it. If minor->master is NULL, it is only set by places that also adjust drm_file->is_master. Therefore, we can safely drop is_master and replace it by an inline helper that matches: drm_file->master && drm_file->master == drm_file->minor->master Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: David Herrmann <dh.herrmann@gmail.com>

2014-06-04gpu: ipu-v3: Move i.MX IPUv3 core driver out of stagingPhilipp Zabel14-3706/+5
The i.MX Image Processing Unit (IPU) contains a number of image processing blocks that sit right in the middle between DRM and V4L2. Some of the modules, such as Display Controller, Processor, and Interface (DC, DP, DI) or CMOS Sensor Interface (CSI) and their FIFOs could be assigned to either framework, but others, such as the dma controller (IDMAC) and image converter (IC) can be used by both. The IPUv3 core driver provides an internal API to access the modules, to be used by both DRM and V4L2 IPUv3 drivers.

2014-04-26imx-drm: ipuv3-crtc: change display enable/disable orderPhilipp Zabel1-3/+7
Now that ipu_dc_disable_channel correctly waits for the channel to finish, we can reorder the enable/disable order to first stop the DC and DI and only then disable the IDMAC. Enabling is done the other way around: IDMAC first, then DC, then DI. This avoids an issue where sometimes the channel would not correctly start, leading to non-working LVDS displays.

2014-04-26imx-drm: ipu-dp: split disabling the DP foreground channel from disabling the DP modulePhilipp Zabel3-23/+51
The former has to be done before disabling the DMFC, the latter has to be done afterwards. Otherwise the DMFC FIFOs never get cleared properly. Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2014-04-26imx-drm: ipu-dc: wait for DC_FC_1 / DP_SF_END interruptPhilipp Zabel1-21/+50

2014-04-26imx-drm: ipu-dmfc: wait for FIFOs to run empty before disablingPhilipp Zabel1-2/+23
Disabling the DMFC module while there is still data in the FIFOs could cause the "new frame before end of frame" error state when the DMFC is enabled again. Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2014-04-26imx-drm: imx-tve: correct DDC property name to 'ddc-i2c-bus'Shawn Guo1-1/+1
Commit 62e3879 (imx-drm: imx-tve: Fix DDC I2C bus property) was trying to use 'ddc-i2c-bus' as the DDC property name (we can see that from the commit log), but unfortunately 'i2c-ddc-bus' which is a typo was actually used in the code. This results in some unnecessary inconsistency and confusions, because all the documented DDC property in device tree bindings use 'ddc-i2c-bus'.

2014-04-25imx-drm: fix hdmi hotplug detection initial stateRussell King1-6/+3
The initial state at boot is assumed to be disconnected, and we hope to receive an interrupt to update the status. Let's be more explicit about the current state - reading the PHY status register tells us the current level of the hotplug signal, which we can report back in the _detect() method.
