[PATCH v8 00/11] Add DRM for stih4xx platforms

by Benjamin Gaignard

This series of patches add the support of DRM/KMS drivers for STMicroelectronics chipsets stih416 and stih407. version 8: - Allow driver to be build as kernel module. - Use Universal Plane instead of legacy code. patches could be found here: git://git.linaro.org/people/benjamin.gaignard/kernel.git on branch: drm_kms_for_next-v8 version 7: - rebased on top of drm-next (2014-07-24) patches could be found here: git://git.linaro.org/people/benjamin.gaignard/kernel.git on branch: drm_kms_for_next-v7 version 6: - rebased on top of new component framework API. patches could be found here: git://git.linaro.org/people/benjamin.gaignard/kernel.git on branch: drm_kms_for_next-v6 version 5: - Rework sti_drm_drv probes functions to support deferred probe. This allow hdmi to delayed framebuffer creation until I2C is available. - Add ops functions in sti_layer structure to simpify GDP and VID code. - Add NOTES file to describe how the DRM concepts are mapped on hardware. patches could be found here: git://git.linaro.org/people/benjamin.gaignard/kernel.git on branch: drm_kms_for_next-v5 version 4: - Remove depency between TVout it subdevices HDMI and HDA - Rework and simplify VTG and VTAC code - Fix numbers of typo and indentation - Remove debug (will be push in separate patches) - Fix remarks done in previous patcheset patches could be found here: git://git.linaro.org/people/benjamin.gaignard/kernel.git on branch: drm_kms_for_next-v4 version 3: - Correctly split code between probe and bind funtions - Squash some commits - remove HQ-VDP device code to have a smaller patcheset, we will introduce it later. patches could be found here: git://git.linaro.org/people/benjamin.gaignard/kernel.git on branch: drm_kms_for_next-v3 version 2: - Use componentized device instead of register sub-devices in master driver probe function - Fix Makefile and Kconfig to only allow built-in compilation patches could be found here: git://git.linaro.org/people/benjamin.gaignard/kernel.git on branch: drm_kms_for_next-v2 version 1: - First path submission Hardware is split in two main blocks: Compositor and TVout. Each of them includes specific hardware IPs and the display timing are controlled by a specific Video Timing Generator hardware IP (VTG). Compositor is made of the follow hardware IPs: - GDP (Generic Display Pipeline) which is an entry point for graphic (RGB) buffers - VDP (Video Diplay Pipeline) which is an entry point for video (YUV) buffers - HQVDP (High Quality Video Display Processor) that supports scaling, deinterlacing and some miscellaneous image quality improvements. It fetches the Video decoded buffers from memory, processes them and pushes them to the Compositor through a HW dedicated bus. - Mixer is responsible of mixing all the entries depending of their respective z-order and layout TVout is divided in 3 parts: - HDMI to generate HDMI signals, depending of chipset version HDMI phy can change. - HDA to generate signals for HD analog TV - VIP to control/switch data path coming from Compositor On stih416 compositor and Tvout are on different dies so a Video Trafic Advance inter-die Communication mechanism (VTAC) is needed. +---------------------------------------------+ +----------------------------------------+ | +-------------------------------+ +----+ | | +----+ +--------------------------+ | | | | | | | | | | | +---------+ +----+ | | | | +----+ +------+ | | | | | | | | | VIP |---->|HDMI| | | | | |GPD +------------->| | | | | | | | | | | | +----+ | | | | +----+ |Mixer |--|-->| | | | | |---|->| switcher| | | | | | | | | | | | | | | | | +----+ | | | | | | | | | | | | | | | |---->|HDA | | | | | +------+ | |VTAC|========>|VTAC| | +---------+ +----+ | | | | | | | | | | | | | | | | Compositor | | | | | | | | TVout | | | +-------------------------------+ | | | | | | +--------------------------+ | | ^ | | | | | | ^ | | | | | | | | | | | | +--------------+ | | | | | | +-------------+ | | | VTG (master) |----->| | | | | |----->| VTG (slave) | | | +--------------+ +----+ | | +----+ +-------------+ | |Digital die | | Analog Die| +---------------------------------------------+ +----------------------------------------+ On stih407 Compositor and Tvout are on the same die +-----------------------------------------------------------------+ | +-------------------------------+ +--------------------------+ | | | | | +---------+ +----+ | | | | +----+ +------+ | | | VIP |---->|HDMI| | | | | |GPD +------------->| | | | | | +----+ | | | | +----+ |Mixer |--|--|->| switcher| | | | | +----+ +-----+ | | | | | | +----+ | | | | |VDP +-->+HQVDP+--->| | | | | |---->|HDA | | | | | +----+ +-----+ +------+ | | +---------+ +----+ | | | | | | | | | | Compositor | | TVout | | | +-------------------------------+ +--------------------------+ | | ^ ^ | | | | | | +--------------+ | | | VTG | | | +--------------+ | |Digital die | +-----------------------------------------------------------------+ In addition of the drivers for the IPs listed before a thin I2C driver (hdmiddc) is used by HDMI driver to retrieve EDID for monitor.

[RFCv3 1/2] device: add dma_params->max_segment_count

by Sumit Semwal

From: Rob Clark <robdclark(a)gmail.com> For devices which have constraints about maximum number of segments in an sglist. For example, a device which could only deal with contiguous buffers would set max_segment_count to 1. The initial motivation is for devices sharing buffers via dma-buf, to allow the buffer exporter to know the constraints of other devices which have attached to the buffer. The dma_mask and fields in 'struct device_dma_parameters' tell the exporter everything else that is needed, except whether the importer has constraints about maximum number of segments.

[PATCH v5 00/18] Exynos SYSMMU (IOMMU) integration with DT and DMA-mapping subsystem

by Marek Szyprowski

Hello Everyone, This is yet another attempt to get Exynos SYSMMU driver with integrated with IOMMU & DMA-mapping subsystems. The main change from previous version is a rebase onto some more pending Exynos DTS patches and minor fixes of the reported issues. Merge plan for this patchset: 1. All iommu related patches (with 'iommu: exynos') can be merged to iommu tree. They don't have any direct dependencies on the DTS, DRM and power domain initialization change - without them the driver will simply not initialize, when no exynos,sysmmu nodes are provided in device tree. Joerg, could you merge those patches? 2. DTS and power domain patches should go to Samsung Exynos tree. Those patches depends on earlier DTS patches for Exynos SoCs, which make this patchset really complete: - 'ARM: DTS: Exynos: convert to generic power domain bindings' (http://www.spinics.net/lists/linux-samsung-soc/msg40584.html) - '[PATCH v4 0/7] Enable HDMI support on Exynos platforms' (http://www.spinics.net/lists/arm-kernel/msg391148.html) - '[PATCH 0/2] Add HDMI support for Exynos5420 platform' (http://www.spinics.net/lists/linux-samsung-soc/msg41364.html) Kukjin, could you merge those patches? 3. Exynos DRM fix. This patch in my opinion should go Exynos DRM tree. Inki, could you merge it? Best regards Marek Szyprowski Samsung R&D Institute Poland Changelog: v5: - rebased onto 'Add HDMI support for Exynos5420 platform' patchset - fixed 'const' issue in 'iommu: exynos: init from dt-specific callback instead of initcall' patch, thanks to Tobias Jakobi for reporting it - fixed copy-paste typo in exynos5250 dts patch v4: http://www.spinics.net/lists/linux-samsung-soc/msg41177.html - rebased onto v3.19-rc4 and other Exynos DTS queued patches - added DTS patch for Exynos 5250 & 5420/5422/5800 v3: http://www.spinics.net/lists/linux-samsung-soc/msg39168.html - rebased onto "[RFC PATCH v4 0/8] Introduce automatic DMA configuration for IOMMU masters" - added some minor fixes for iommu and dma-mapping frameworks v2: http://thread.gmane.org/gmane.linux.kernel.iommu/6472/ - rebased onto "[RFC PATCH v3 0/7] Introduce automatic DMA configuration for IOMMU masters" patches: http://www.spinics.net/lists/arm-kernel/msg362076.html - changed initialization from bus notifiers to DT related callbacks - removed support for separate IO address spaces - this will be discussed separately after the basic support gets merged - removed support for power domain notifier-based runtime power management - this also will be discussed separately later v1: https://lkml.org/lkml/2014/8/5/183 - initial version, feature complete, completely rewrote integration approach Patch summary: Marek Szyprowski (18): drm: exynos: detach from default dma-mapping domain on init arm: exynos: pm_domains: add support for devices registered before arch_initcall ARM: dts: exynos4: add sysmmu nodes ARM: dts: exynos5250: add sysmmu nodes ARM: dts: exynos5420: add sysmmu nodes iommu: exynos: don't read version register on every tlb operation iommu: exynos: remove unused functions iommu: exynos: remove useless spinlock iommu: exynos: refactor function parameters to simplify code iommu: exynos: remove unused functions, part 2 iommu: exynos: remove useless device_add/remove callbacks iommu: exynos: add support for binding more than one sysmmu to master device iommu: exynos: add support for runtime_pm iommu: exynos: rename variables to reflect their purpose iommu: exynos: document internal structures iommu: exynos: remove excessive includes and sort others alphabetically iommu: exynos: init from dt-specific callback instead of initcall iommu: exynos: add callback for initializing devices from device tree arch/arm/boot/dts/exynos4.dtsi | 118 +++++++ arch/arm/boot/dts/exynos4210.dtsi | 23 ++ arch/arm/boot/dts/exynos4x12.dtsi | 82 +++++ arch/arm/boot/dts/exynos5250.dtsi | 250 +++++++++++++++ arch/arm/boot/dts/exynos5420.dtsi | 181 +++++++++++ arch/arm/mach-exynos/pm_domains.c | 9 +- drivers/gpu/drm/exynos/exynos_drm_iommu.c | 3 + drivers/iommu/exynos-iommu.c | 492 ++++++++++++++---------------- 8 files changed, 888 insertions(+), 270 deletions(-) -- 1.9.2
