This patch is based on exynos-drm-next branch of Inki Dae's tree at: git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos.git DECON(Display and Enhancement Controller) is the new IP in exynos7 SOC for generating video signals using pixel data. DECON driver can be used to drive 2 different interfaces on Exynos7: DECON-INT(video controller) and DECON-EXT(Mixer for HDMI) The existing FIMD driver code was used as a template to create DECON driver. Only DECON-INT is supported as of now, and DECON-EXT support will be added later. The current version of the driver supports video mode displays.

LP_OUTPUT_HOLD is only in MIPI_PORT_CTRL(PORT_A) even for PORT_C in case of dual link. In the dual link implementation, the bit is correctly set or unset for hardcoded PORT_A, but for bit update the register base value is read by using MIPI_PORT_CTRL(port) in a loop. The second iteration will read base value from PORT_C and program for PORT_A. Mostly in case of dual link all other bit values should be same, but logically we should read from PORT_A. So hardcode to read initial value from PORT_A as well. Signed-off-by:

This looked like an odd regression from commit ec5cc0f9 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Thu Jun 12 10:28:55 2014 +0100 drm/i915: Restrict GPU boost to the RCS engine but in reality it undercovered a much older coherency bug. The issue that boosting the GPU frequency on the BCS ring was masking was that we could wake the CPU up after completion of a BCS batch and inspect memory prior to the write cache being fully evicted. In order to serialise the breadcrumb interrupt (and so ensure that the CPU's view of memory is coherent) we need to perform a post-sync operation in the MI_FLUSH_DW. v2: Fix all the MI_FLUSH_DW (bsd plus the duplication in execlists). Also fix the invalidate_domains mask in gen8_emit_flush() for ring != VCS. Testcase: gpuX-rcs-gpu-read-after-write Signed-off-by:

Nothing in Bspec seems to indicate that we actually needs this, and it looks like can't work since by this point the pipe is off and so vblanks won't really happen any more.

The exynos_plane_dpms function handles enabled flag of exynos plane and calls internal hw driver callback function for hw overlay on/off. But it causes state disharmory problem currently and is will be obstacle to apply atomic operation later to keep non-standard per-plane dpms state like enabled flag. Let's remove enabled flag, it just stop to recall internal callback function but hw drivers can handle it properly. And call internal callback function directly then we can remove unnecessary exynos_plane_dpms function Signed-off-by:

As per the specififcation, the SB_DevFn is the PCI_DEVFN of the target device and not the source. So PCI_DEVFN(2,0) is not correct. Further the port ID should be enough to identify devices unless they are MFD. The SB_DevFn was intended to remove ambiguity in case of these MFD devices. For non MFD devices the recommendation for the target device IP was to ignore these fields, but not all of them followed the recommendation. Some like CCK ignore these fields and hence PCI_DEVFN(2, 0) works and so does PCI_DEVFN(0, 0) as it works for DPIO. The issue came to light because of GPIONC which was not getting programmed correctly with PCI_DEVFN(2, 0). It turned out that this did not follow the recommendation and expected 0 in this field. In general the recommendation is to use SB_DevFn as PCI_DEVFN(0, 0) for all devices except target PCI devices. Signed-off-by:

The Exynos DRM driver doesn't follow the correct API when dealing with dma_{alloc, mmap, free}_attrs functions and the DMA_ATTR_NO_KERNEL_MAPPING attribute. When a IOMMU is not available and the DMA_ATTR_NO_KERNEL_MAPPING is used, the driver should use the pointer returned by dma_alloc_attr() as a cookie. The Exynos DRM driver directly uses the non-requested virtual kernel address returned by the DMA mapping subsystem. This just works now because the non-IOMMU codepath doesn't obey DMA_ATTR_NO_KERNEL_MAPPING but we need to fix it before fixing the DMA layer. Signed-off-by:Carlo Caione <carlo@caione.org> Acked-by:

This changes breaks hdmi out on Odroid U2 (linux-next with added Marek Szyprowski v4 hdmi patchset from linux-samsung-soc ML).
