The changes outside of the typical drivers/nvdimm/ and drivers/acpi/nfit.[ch] paths are related to the removal of IORESOURCE_CACHEABLE, the introduction of memremap(), and the introduction of ZONE_DEVICE + devm_memremap_pages(). Summary: - Introduce ZONE_DEVICE and devm_memremap_pages() as a generic mechanism for adding device-driver-discovered memory regions to the kernel's direct map. This facility is used by the pmem driver to enable pfn_to_page() operations on the page frames returned by DAX ('direct_access' in 'struct block_device_operations'). For now, the 'memmap' allocation for these "device" pages comes from "System RAM". Support for allocating the memmap from device memory will arrive in a later kernel. - Introduce memremap() to replace usages of ioremap_cache() and ioremap_wt(). memremap() drops the __iomem annotation for these mappings to memory that do not have i/o side effects. The replacement of ioremap_cache() with memremap() is limited to the pmem driver to ease merging the api change in v4.3. Completion of the conversion is targeted for v4.4. - Similar to the usage of memcpy_to_pmem() + wmb_pmem() in the pmem driver, update the VFS DAX implementation and PMEM api to provide persistence guarantees for kernel operations on a DAX mapping. - Convert the ACPI NFIT 'BLK' driver to map the block apertures as cacheable to improve performance. - Miscellaneous updates and fixes to libnvdimm including support for issuing "address range scrub" commands, clarifying the optimal 'sector size' of pmem devices, a clarification of the usage of the ACPI '_STA' (status) property for DIMM devices, and other minor fixes" * tag 'libnvdimm-for-4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: (34 commits) libnvdimm, pmem: direct map legacy pmem by default libnvdimm, pmem: 'struct page' for pmem libnvdimm, pfn: 'struct page' provider infrastructure x86, pmem: clarify that ARCH_HAS_PMEM_API implies PMEM mapped WB add devm_memremap_pages mm: ZONE_DEVICE for "device memory" mm: move __phys_to_pfn and __pfn_to_phys to asm/generic/memory_model.h dax: drop size parameter to ->direct_access() nd_blk: change aperture mapping from WC to WB nvdimm: change to use generic kvfree() pmem, dax: have direct_access use __pmem annotation dax: update I/O path to do proper PMEM flushing pmem: add copy_from_iter_pmem() and clear_pmem() pmem, x86: clean up conditional pmem includes pmem: remove layer when calling arch_has_wmb_pmem() pmem, x86: move x86 PMEM API to new pmem.h header libnvdimm, e820: make CONFIG_X86_PMEM_LEGACY a tristate option pmem: switch to devm_ allocations devres: add devm_memremap libnvdimm, btt: write and validate parent_uuid ...

I've one other new driver from freescale on my radar, it's been posted and reviewed, I'd just like to get someone to give it a last look, so maybe I'll send it or maybe I'll leave it. There is no major nouveau changes in here, Ben was working on something big, and we agreed it was a bit late, there wasn't anything else he considered urgent to merge. There might be another msm pull for some bits that are waiting on arm-soc, I'll see how we time it. This touches some "of" stuff, acks are in place except for the fixes to the build in various configs,t hat I just applied. Summary: New drivers: - virtio-gpu: KMS only pieces of driver for virtio-gpu in qemu. This is just the first part of this driver, enough to run unaccelerated userspace on. As qemu merges more we'll start adding the 3D features for the virgl 3d work. - amdgpu: a new driver from AMD to driver their newer GPUs. (VI+) It contains a new cleaner userspace API, and is a clean break from radeon moving forward, that AMD are going to concentrate on. It also contains a set of register headers auto generated from AMD internal database. core: - atomic modesetting API completed, enabled by default now. - Add support for mode_id blob to atomic ioctl to complete interface. - bunch of Displayport MST fixes - lots of misc fixes. panel: - new simple panels - fix some long-standing build issues with bridge drivers radeon: - VCE1 support - add a GPU reset counter for userspace - lots of fixes. amdkfd: - H/W debugger support module - static user-mode queues - support killing all the waves when a process terminates - use standard DECLARE_BITMAP i915: - Add Broxton support - S3, rotation support for Skylake - RPS booting tuning - CPT modeset sequence fixes - ns2501 dither support - enable cmd parser on haswell - cdclk handling fixes - gen8 dynamic pte allocation - lots of atomic conversion work exynos: - Add atomic modesetting support - Add iommu support - Consolidate drm driver initialization - and MIC, DECON and MIPI-DSI support for exynos5433 omapdrm: - atomic modesetting support (fixes lots of things in rewrite) tegra: - DP aux transaction fixes - iommu support fix msm: - adreno a306 support - various dsi bits - various 64-bit fixes - NV12MT support rcar-du: - atomic and misc fixes sti: - fix HDMI timing complaince tilcdc: - use drm component API to access tda998x driver - fix module unloading qxl: - stability fixes" * 'drm-next' of git://people.freedesktop.org/~airlied/linux: (872 commits) drm/nouveau: Pause between setting gpu to D3hot and cutting the power drm/dp/mst: close deadlock in connector destruction. drm: Always enable atomic API drm/vgem: Set unique to "vgem" of: fix a build error to of_graph_get_endpoint_by_regs function drm/dp/mst: take lock around looking up the branch device on hpd irq drm/dp/mst: make sure mst_primary mstb is valid in work function of: add EXPORT_SYMBOL for of_graph_get_endpoint_by_regs ARM: dts: rename the clock of MIPI DSI 'pll_clk' to 'sclk_mipi' drm/atomic: Don't set crtc_state->enable manually drm/exynos: dsi: do not set TE GPIO direction by input drm/exynos: dsi: add support for MIC driver as a bridge drm/exynos: dsi: add support for Exynos5433 drm/exynos: dsi: make use of array for clock access drm/exynos: dsi: make use of driver data for static values drm/exynos: dsi: add macros for register access drm/exynos: dsi: rename pll_clk to sclk_clk drm/exynos: mic: add MIC driver of: add helper for getting endpoint node of specific identifiers drm/exynos: add Exynos5433 decon driver ...

Sync lines can also be driven on rising or falling pixel clock edge, but additionally the HW can be configured to drive the sync lines on opposite clock edge from the data lines. This opposite edge setting does not make any sense, as the same effect can be achieved by just setting the sync lines to be driven on the other edge compared to the data lines. It feels like some kind of backward compatibility option, even if all DSS versions seem to have the same implementation. To simplify the code and configuration of the signals, and to make the dispc timings more compatible with what is used on other platforms, let's just remove the whole opposite-edge support. The drivers that used OMAPDSS_DRIVE_SIG_OPPOSITE_EDGES setting are changed so that they use the opposite setting from the data edge. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

The reason for this suggested Andrzej Hajda: the DP clock was disabled. This clock is required by Display Port and is enabled by bootloader. However when FIMD driver probing was deferred, the display power domain was turned off. This effectively reset the value of DP clock enable register. When exynos-dp is later probed, the clock is not enabled and display is not properly configured: exynos-dp 145b0000.dp-controller: Timeout of video streamclk ok exynos-dp 145b0000.dp-controller: unable to config video Fixes: 2d2c9a8d0a4f ("ARM: dts: add display power domain for exynos5250") Cc: <stable@vger.kernel.org> Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Reported-by: Javier Martinez Canillas <javier.martinez@collabora.co.uk> Tested-by: Javier Martinez Canillas <javier.martinez@collabora.co.uk> Tested-by: Andreas Färber <afaerber@suse.de> Signed-off-by: Inki Dae <inki.dae@samsung.com>

* / OMAPDSS: fix regression with display sysfs filesTomi Valkeinen2015-02-261-0/+1
|/ | | | | | | | | | | | | | | | | | omapdss's sysfs directories for displays used to have 'name' file, giving the name for the display. This file was later renamed to 'display_name' to avoid conflicts with i2c sysfs 'name' file. Looks like at least xserver-xorg-video-omap3 requires the 'name' file to be present. To fix the regression, this patch creates new kobjects for each display, allowing us to create sysfs directories for the displays. This way we have the whole directory for omapdss, and there will be no sysfs file clashes with the underlying display device's sysfs files. We can thus add the 'name' sysfs file back.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | In omapdss_of_find_source_for_first_ep, we retrieve a source endpoint's DT node, and then see what omapdss output has the matching device_node pointer in omap_dss_find_output_by_node. For all DPI and SDI outputs, the device_node pointer is set as the parent's DSS device_node pointer. If the source is one of these outputs, the above method won't work. To get the correct output for ports within DSS(and in other cases in the future, where multiple ports might be under one device), we require additional information which is exclusive to the output port. We create a new field in omap_dss_device called 'port_num', this provides port number of the output port corresponding to this device. When searching for the source endpoint in DT, we extract the 'reg' property from the port corresponding to the endpoint source. From the list of registered outputs, we pick out that output which has both dev->of_node and port_num matching with the device_node pointer and 'reg' of the source endpoint node from DT. For encoder blocks(the ones which have both an input and output port), we need to set the port_num as the 'reg' property for the output port as defined in the DT bindings. We set port_num to 1 in the tfp410 and tpd12s015 encoder drivers. Signed-off-by: Archit Taneja <archit@ti.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

| * OMAPDSS: add hdmi ops to hdmi_ops and omap_dss_driverTomi Valkeinen2014-07-041-0/+9
| | | | | | | | | | | | | | | | | | Add two new ops for HDMI: set_infoframe() and set_hdmi_mode(). The first one can be used to specify the infoframe that should be sent to the HDMI monitor, and the second one is used to enable HDMI mode (versus DVI mode).

Among the bigger ones: - Removal of Samsung s5pc100 and s5p64xx platforms. Both of these have lacked active support for quite a while, and after asking around nobody showed interest in keeping them around. If needed, they could be resurrected in the future but it's more likely that we would prefer reintroduction of them as DT and multiplatform-enabled platforms instead. - OMAP4 controller code register define diet. They defined a lot of registers that were never actually used, etc. - Move of some of the Tegra platform code (PMC, APBIO, fuse, powergate) to drivers/soc so it can be shared with 64-bit code. This also converts them over to traditional driver models where possible. - Removal of legacy gpio-samsung driver, since the last users have been removed (moved to pinctrl) Plus a bunch of smaller changes for various platforms that sort of dissapear in the diffstat for the above. clps711x cleanups, shmobile header file refactoring/moves for multiplatform friendliness, some misc cleanups, etc" * tag 'cleanup-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (117 commits) drivers: CCI: Correct use of ! and & video: clcd-versatile: Depend on ARM video: fix up versatile CLCD helper move MAINTAINERS: Add sdhci-st file to ARCH/STI architecture ARM: EXYNOS: Fix build breakge with PM_SLEEP=n MAINTAINERS: Remove Kirkwood ARM: tegra: Convert PMC to a driver soc/tegra: fuse: Set up in early initcall ARM: tegra: Always lock the CPU reset vector ARM: tegra: Setup CPU hotplug in a pure initcall soc/tegra: Implement runtime check for Tegra SoCs soc/tegra: fuse: fix dummy functions soc/tegra: fuse: move APB DMA into Tegra20 fuse driver soc/tegra: Add efuse and apbmisc bindings soc/tegra: Add efuse driver for Tegra ARM: tegra: move fuse exports to soc/tegra/fuse.h ARM: tegra: export apb dma readl/writel ARM: tegra: Use a function to get the chip ID ARM: tegra: Sort includes alphabetically ARM: tegra: Move includes to include/soc/tegra ...
