2016-01-11drm/i915/bios: add support for MIPI sequence block v3Jani Nikula
The changes since the sequence block v2 are: * The whole MIPI bios data block has a separate 32-bit size field since v3, stored after the version. This facilitates big sequences. * The size of the panel specific sequence blocks has grown to 32 bits. This facilitates big sequences. * The elements within sequences now have an 8-bit size field following the operation byte. This facilitates skipping unknown new operation bytes, i.e. forward compatibility. v2 (of the patch): use DRM_ERROR for unknown operation byte v3 (of the patch): even more bounds checking (Ville) Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1452518102-3154-1-git-send-email-jani.nikula@intel.com

2016-01-11drm/i915: Arm the unclaimed mmio debugs on suspend pathMika Kuoppala
If we go into suspend with unclaimed access detected, it would be nice to catch that access on a next suspend path. So instead of just notifying about it, arm the unclaimed mmio checks on suspend side. We want to keep the asymmetry on resume, as if it was on resume path, it was not driver that is responsible so no point in arming mmio debugs.

2016-01-11drm/i915: Enable mmio_debug for vlv/chvMika Kuoppala
With commit 8ac3e1bb76cc ("drm/i915: Add non claimed mmio checking for vlv/chv") we now have chv/vlv support in place for detecting unclaimed access. Also the perf hit of extra mmio read is now only suffered if mmio_debug is set. This allows us to stuff the macro for unclaimed reg detection inside a generic gen6 register access, as now all gens using these macros uses also unclaimed debugs, the one exception being snb. We gain more clean and generic macros and only downside is that snb will suffer one branch perf hit without upside. Note that the hsw write path debug register check now happens before fifo check, but this should not make any real difference. As vlv/chv use the generic gen6 access macros, the consequence is that they gain the mmio_debug feature.

2016-01-11drm/amdgpu: add irq domain supportAlex Deucher
Hardware blocks on the GPU like ACP generate interrupts in the GPU interrupt controller, but are driven by a separate driver. Add an irq domain to the GPU driver so that blocks like ACP can register a Linux interrupt.

2016-01-11drm/amdgpu/cgs: add an interface to access PCI resourcesAlex Deucher
This provides an interface to get access to the base address of PCI resources (MMIO, DOORBELL, etc.). Only MMIO and DOORBELL are implemented right now. This is necessary to properly utilize shared drivers on platform devices. IP modules can use this interface to get the base address of the resource and add any additional offset and set the size when setting up the platform driver(s).
