2016-04-20drm/exynos: drop struct_mutex from exynos_drm_gem_get_ioctlDaniel Vetter
The only things this protects is reading ->flags and ->size, both of which are invariant over the lifetime of an exynos gem bo. So no locking needed at all (besides that, nothing protects the writers anyway). Aside: exynos_gem_obj->size is redundant with exynos_gem_obj->base.size and probably should be removed. v2: Use _unlocked unreference (Daniel Stone).

2016-04-20drm/exynos: drop struct_mutex from exynos_gem_map_sgt_with_dmaDaniel Vetter
The sg table isn't refcounted, there's no corresponding locking for unmapping and drm_map_sg is ok with being called concurrently. So drop the locking since it doesn't protect anything.

2016-04-20drm/exynos: Drop dev->struct_mutex from mmap offset functionDaniel Vetter
Simply forgotten about this when I was doing my general cleansing of simple gem mmap offset functions. There's nothing but core functions called here, and they all have their own protection already. Aside: DRM_ERROR for userspace controlled input isn't great, but that's for another patch. v2: Use _unlocked unreference (Daniel Stone).

2016-04-13drm/exynos: Use VIDEO_SAMSUNG_S5P_G2D=n as G2D Kconfig dependencyJavier Martinez Canillas
Commit 254d4d111ee1 ("drm/exynos: Add dependency for G2D in Kconfig") made the DRM_EXYNOS_G2D symbol to only be selectable if the s5p-g2d V4L2 driver is not enabled, since both use the same HW IP block. But added the dependency as depends on !VIDEO_SAMSUNG_S5P_G2D which isn't correct since Kconfig expressions are not boolean but tristate. So it will only evaluate to 'n' if VIDEO_SAMSUNG_S5P_G2D=y but it will evaluate to m if VIDEO_SAMSUNG_S5P_G2D=m. This means that both the V4L2 and DRM drivers can be enabled if the former is enabled as a module, which is not what we want.

Split the dp core driver from exynos directory to bridge directory, and rename the core driver to analogix_dp_*, rename the platform code to exynos_dp. Beside the new analogix_dp driver would export six hooks. "analogix_dp_bind()" and "analogix_dp_unbind()" "analogix_dp_suspned()" and "analogix_dp_resume()" "analogix_dp_detect()" and "analogix_dp_get_modes()" The bind/unbind symbols is used for analogix platform driver to connect with analogix_dp core driver. And the detect/get_modes is used for analogix platform driver to init the connector. They reason why connector need register in helper driver is rockchip drm haven't implement the atomic API, but Exynos drm have implement it, so there would need two different connector helper functions, that's why we leave the connector register in helper driver.

This patch changes device pointer provided to all calls to DMA-mapping subsystem from the virtual exynos-drm 'device' to the real device pointer of one of the CRTC devices (decon, fimd or mixer). This way no more hacks will be needed to configure proper DMA-mapping address space on the common virtual exynos-drm device. This change also removes the need for some hacks in IOMMU related code. It also finally solves the problem of Exynos DRM driver not working on ARM64 architecture, which provides noop-based DMA-mapping operations for virtual platform devices.

2016-02-01drm/exynos: dp: Fix panel and bridge lookup logicJavier Martinez Canillas
Commit a9fa852886fd ("drm/exynos: dp: add of_graph dt binding support for panel") made the Exynos DP DT binding more consistent since the OF graph could be used to lookup either a panel or a bridge device node. Before that commit, a panel would be looked up using a phandle and a bridge using the OF graph which made the DT binding not consistent. But the patch broke the later case since not finding a panel dev node would cause the driver's to do a probe deferral instead of attempting to lookup a bridge device node associated with the remote endpoint. So instead of returning a -EPROBE_DEFER if a panel is not found, check if there's a bridge and only do a probe deferral if both aren't found.

Merge second patch-bomb from Andrew Morton: - more MM stuff: - Kirill's page-flags rework - Kirill's now-allegedly-fixed THP rework - MADV_FREE implementation - DAX feature work (msync/fsync). This isn't quite complete but DAX is new and it's good enough and the guys have a handle on what needs to be done - I expect this to be wrapped in the next week or two. - some vsprintf maintenance work - various other misc bits * emailed patches from Andrew Morton <akpm@linux-foundation.org>: (145 commits) printk: change recursion_bug type to bool lib/vsprintf: factor out %pN[F] handler as netdev_bits() lib/vsprintf: refactor duplicate code to special_hex_number() printk-formats.txt: remove unimplemented %pT printk: help pr_debug and pr_devel to optimize out arguments lib/test_printf.c: test dentry printing lib/test_printf.c: add test for large bitmaps lib/test_printf.c: account for kvasprintf tests lib/test_printf.c: add a few number() tests lib/test_printf.c: test precision quirks lib/test_printf.c: check for out-of-bound writes lib/test_printf.c: don't BUG lib/kasprintf.c: add sanity check to kvasprintf lib/vsprintf.c: warn about too large precisions and field widths lib/vsprintf.c: help gcc make number() smaller lib/vsprintf.c: expand field_width to 24 bits lib/vsprintf.c: eliminate potential race in string() lib/vsprintf.c: move string() below widen_string() lib/vsprintf.c: pull out padding code from dentry_name() printk: do cond_resched() between lines while outputting to consoles ...
2016-01-17Merge tag 'sound-4.5-rc1' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "We've had quite busy weeks in this cycle. Looking at ALSA core, the significant changes are a few fixes wrt timer and sequencer ioctls that have been revealed by fuzzer recently. Other than that, ASoC core got a few updates about DAI link handling, but these are rather straightforward refactoring. In drivers scene, ASoC received quite lots of new drivers in addition to bunch of updates for still ongoing Intel Skylake support and topology API. HD-audio gained a new HDMI/DP hotplug notification via component. FireWire got a pile of code refactoring/updates with SCS.1x driver integration. More highlights are shown below. [ NOTE: this contains also many commits for DRM. This is due to the pull of drm stable branch into sound tree, as the base of i915 audio component work for HD-audio. The highlights below don't contain these DRM changes, as these are supposed to be pulled via drm tree in anyway sooner or later. ] Core: - Handful fixes to harden ALSA timer and sequencer ioctls against races reported by syzkaller fuzzer - Irq description string can be unique to each card; only for HD-audio for now ASoC: - Conversion of the array of DAI links to a list for supporting dynamically adding and removing DAI links - Topology API enhancements to make everything more component based and being able to specify PCM links via topology - Some more fixes for the topology code, though it is still not final and ready for enabling in production; we really need to get to the point where that can be done - A pile of changes for Intel SkyLake drivers which hopefully deliver some useful initial functionality for systems with this chipset, though there is more work still to come - Lots of new features and cleanups for the Renesas drivers - ANC support for WM5110 - New drivers: Imagination Technologies IPs, Atmel class D speaker, Cirrus CS47L24 and WM1831, Dialog DA7128, Realtek RT5659 and RT56156, Rockchip RK3036, TI PC3168A, and AMD ACP - Rename PCM1792a driver to be generic pcm179x HD-Audio: - Use audio component for i915 HDMI/DP hotplug handling - On-demand binding with i915 driver - bdl_pos_adj parameter adjustment for Baytrail controllers - Enable power_save_node for CX20722; this shouldn't lead to regression, hopefully - Kabylake HDMI/DP codec support - Quirks for Lenovo E50-80, Dell Latitude E-series, and other Dell machines - A few code refactoring FireWire: - Lots of code cleanup and refactoring - Integrate the support of SCS.1x devices into snd-oxfw driver; snd-scs1x driver is obsoleted USB-audio: - Fix possible NULL dereference at disconnection - A regression fix for Native Instruments devices Misc: - A few code cleanups of fm801 driver" * tag 'sound-4.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (722 commits) ALSA: timer: Code cleanup ALSA: timer: Harden slave timer list handling ALSA: hda - Add fixup for Dell Latitidue E6540 ALSA: timer: Fix race among timer ioctls ALSA: hda - add codec support for Kabylake display audio codec ALSA: timer: Fix double unlink of active_list ALSA: usb-audio: Fix mixer ctl regression of Native Instrument devices ALSA: hda - fix the headset mic detection problem for a Dell laptop ALSA: hda - Fix white noise on Dell Latitude E5550 ALSA: hda_intel: add card number to irq description ALSA: seq: Fix race at timer setup and close ALSA: seq: Fix missing NULL check at remove_events ioctl ALSA: usb-audio: Avoid calling usb_autopm_put_interface() at disconnect ASoC: hdac_hdmi: remove unused hdac_hdmi_query_pin_connlist ASoC: AMD: Add missing include file ALSA: hda - Fixup inverted internal mic for Lenovo E50-80 ALSA: usb: Add native DSD support for Oppo HA-1 ASoC: Make aux_dev more like a generic component ASoC: bcm2835: cleanup includes by ordering them alphabetically ASoC: AMD: Manage ACP 2.x SRAM banks power ...
2016-01-15mm, dax, gpu: convert vm_insert_mixed to pfn_tDan Williams
Convert the raw unsigned long 'pfn' argument to pfn_t for the purpose of evaluating the PFN_MAP and PFN_DEV flags. When both are set it triggers _PAGE_DEVMAP to be set in the resulting pte. There are no functional changes to the gpu drivers as a result of this conversion.
