| | * | drm/exynos: simplify sleep PM opsAndrzej Hajda2015-12-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PM ops in exynos_drm_drv were split into two separate function as they were used also by drm device. Since PM ops have been removed from drm device, the functions can be merged together. Signed-off-by: Andrzej Hajda <a.hajda@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com>
| | * | drm/exynos: dsi: add runtime pm supportInki Dae2015-12-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds runtime pm interfaces to dsi driver. Each sub driver should control not only its own clocks and regulator but also its power domain. For this, it removes existing exynos_dsi_poweron/poweroff interfaces and uses runtime pm interfaces instead. Signed-off-by: Inki Dae <inki.dae@samsung.com>

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 ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Exynos GEM objects contains an array of pointers to the pages, which the allocated buffer consists of. Till now the code used some hacks (like relying on DMA-mapping internal structures or using ARM-specific dma_to_pfn helper) to build this array. This patch fixes this by adding proper call to dma_get_sgtable_attrs() and using the acquired scatter-list to construct needed array. This approach is more portable (work also for ARM64) and finally fixes the layering violation that was present in this code.

* | drm/exynos: cleanup name of gem object for exynos_drmJoonyoung Shim2015-10-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Struct of gem object in exynos_drm driver is struct exynos_drm_gem_obj. It's too long and we can know its meaning of name without _obj postfix. We use several names to variable name of gem object for exynos_drm - exynos_gem_obj, gem_obj and obj. Especially "obj" name can cause misunderstanding with variable name "obj" of struct drm_gem_object. This will clean about name of gem object for exynos_drm as follows. s/struct exynos_drm_gem_obj/struct exynos_drm_gem s/exynos_gem_obj or gem_obj or obj/exynos_gem Signed-off-by: Joonyoung Shim <jy0922.shim@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com>
* | drm/exynos: fix to detach device of iommuJoonyoung Shim2015-10-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The arm_iommu_detach_device() is a function to detach device of iommu attached by arm_iommu_attach_device(). The exynos-drm uses arm_iommu_attach_device() so it should use arm_iommu_detach_device() to detach device of iommu, not iommu_detach_device(). The drm_release_iommu_mapping() is a function to release mapping of iommu created by arm_iommu_create_mapping(). It is called by exynos_drm_unload() so shouldn't be called by drm_iommu_detach_device(). Signed-off-by: Joonyoung Shim <jy0922.shim@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com>

| | | | | | | | | | | | | | | | | | Define DEFAULT_WIN as zero to help set the primary plane on all CRTCs. Some CRTCs were defining a variable to store the default window, but that is not necessary as the default (primary) window is always the window zero.

Waiting in atomic context is not the best idea in general. Hopefully, waiting occurs only when Video Processor fails to reset correctly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently driver tries to set specific HDMI-PHY registers in three situations: - before reset, - before power off, - after applying HDMI-PHY configuration. First two cases seems to be unnecessary - register contents will be lost anyway. The third case can be merged with HDMI-PHY configuration by fixing the last byte of configuration data. The patch has been tested with following platforms: - exynos4210-universal_c210, - exynos4412-odroidu3, - exynos5422-odroidxu3.
