Rename the feature from RCAR_DU_FEATURE_DEFR8 to RCAR_DU_FEATURE_EXT_CTRL_REGS to cover all extended control registers in addition to the DEFR8 register. Usage of the feature is refactored to optimize runtime operation and prepare for external clock support. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

If an encoder fails to initialize the device can still be used without the failed encoder. Don't propagate the error out of the probe function but just skip the failed encoder. As a special case a deferred probe request from the encoder is still propagated out of the probe function in order not to break the deferred probing mechanism.

Merge branch 'drm-sti-next-2014-12-11' of http://git.linaro.org/people/benjamin.gaignard/kernel into drm-next This series of patches fix various issues in STI drm driver. Now HDMI i2c adapter could be selected in device tree and plug detection doesn't use gpio anymore. I also had fix some signal timing problems after testing the driver on more hardware. The remaining patches attemps to simplify the code and prepare the next evolutions like DVO and auxiliary CRTC support * 'drm-sti-next-2014-12-11' of http://git.linaro.org/people/benjamin.gaignard/kernel: drm: sti: correctly cleanup CRTC and planes drm: sti: add HQVDP plane drm: sti: add cursor plane drm: sti: enable auxiliary CRTC drm: sti: fix delay in VTG programming drm: sti: prepare sti_tvout to support auxiliary crtc drm: sti: use drm_crtc_vblank_{on/off} instead of drm_vblank_{on/off} drm: sti: fix hdmi avi infoframe drm: sti: remove event lock while disabling vblank drm: sti: simplify gdp code drm: sti: clear all mixer control drm: sti: remove gpio for HDMI hot plug detection drm: sti: allow to change hdmi ddc i2c adapter

Should probably just init this in the GMbus code all the time, based on the cdclk and HPLL like we do on newer platforms.

High Quality Video Data Plane is hardware IP dedicated to video rendering. Compare to GPD (graphic planes) it have better scaler capabilities. HQVDP use VID layer to push data into hardware compositor without going into DDR. From data flow point of view HQVDP and VID are nested so HQVPD update/disable VID.

Drivers where the DRM objects have a lifetime that extends beyond that of the DRM device need to zero out the DRM object memory to void stale data such as properties.

I was playing with clang and oh surprise! a warning trigerred by -Wshift-overflow (gcc doesn't have this one): WA_SET_BIT_MASKED(GEN7_GT_MODE, GEN6_WIZ_HASHING_MASK | GEN6_WIZ_HASHING_16x4); drivers/gpu/drm/i915/intel_ringbuffer.c:786:2: warning: signed shift result (0x28002000000) requires 43 bits to represent, but 'int' only has 32 bits [-Wshift-overflow] WA_SET_BIT_MASKED(GEN7_GT_MODE, ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/gpu/drm/i915/intel_ringbuffer.c:737:15: note: expanded from macro 'WA_SET_BIT_MASKED' WA_REG(addr, _MASKED_BIT_ENABLE(mask), (mask) & 0xffff) Turned out GEN6_WIZ_HASHING_MASK was already shifted by 16, and we were trying to shift it a bit more. The other thing is that it's not the usual case of setting WA bits here, we need to have separate mask and value. To fix this, I've introduced a new _MASKED_FIELD() macro that takes both the (unshifted) mask and the desired value and the rest of the patch ripples through from it.

When we unplug a dp mst branch we unreference the entire tree from the root towards the leaves. Which is ok, since that's the way the pointers and so also the refcounts go. But when we drop the reference we must make sure that we remove the branches/ports from the lists/pointers before dropping the reference. Otherwise the get_validated functions will still return it instead of returning NULL (which indicates a potentially on-going unplug). The mst branch destroy gets this right for ports: First it deletes the port from the ports list, then it unrefs. But the ports destroy function gets it wrong: First it unrefs, then it drops the ref. Which means a zombie mst branch can still be validate with get_validated_mstb_ref when it shouldn't. Fix this.

On MST systems the monitors don't appear when we set the fb up, but plymouth opens the drm device and holds it open while they come up, when plymouth finishes and lastclose gets called we don't do the delayed fb probe, so the monitor never appears on the console. Fix this by moving the delayed checking into the mode restore. v2: Daniel suggested that ->delayed_hotplug is set under the mode_config mutex, so we should check it under that as well, while we are in the area.
