dmaengine: tegra-adma: Add support for Tegra210 ADMA

2016-05-13T09:26:24+00:00

Add support for the Tegra210 Audio DMA controller that is used for transferring data between system memory and the Audio sub-system. The driver only supports cyclic transfers because this is being solely used for audio. This driver is based upon the work by Dara Ramesh . Signed-off-by: Jon Hunter Signed-off-by: Vinod Koul

dmaengine: mv_xor: Allow selecting mv_xor for mvebu only compatible SoC

2016-05-03T06:57:47+00:00

Armada 3700 SoC uses the mv_xor driver but don't select anymore the PLAT_ORION symbol. This commit extends the dependency of the mv_xor driver to the more modern SoCs only compatible with ARCH_MVEBU, which allows using it with the Armada 3700 SoC. In the same time it also add the COMPILE_TEST dependency allowing a wider test coverage. Signed-off-by: Gregory CLEMENT Signed-off-by: Vinod Koul

dmaengine: vdma: Add 64 bit addressing support to the driver

2016-04-06T15:41:14+00:00

This VDMA is a soft ip, which can be programmed to support 32 bit addressing or greater than 32 bit addressing. When the VDMA ip is configured for 32 bit address space the buffer address is specified by a single register (0x5C for MM2S and 0xAC for S2MM channel). When the VDMA core is configured for an address space greater than 32 then each buffer address is specified by a combination of two registers. The first register specifies the LSB 32 bits of address, while the next register specifies the MSB 32 bits of address. For example, 5Ch will specify the LSB 32 bits while 60h will specify the MSB 32 bits of the first start address. So we need to program two registers at a time. This patch adds the 64 bit addressing support to the vdma driver. Signed-off-by: Anurag Kumar Vulisha Signed-off-by: Kedareswara rao Appana Signed-off-by: Vinod Koul

Merge tag 'sound-4.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

2016-01-17T20:05:31+00:00

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 ...

ASoC: samsung: pass filter function as pointer

2015-11-21T13:27:22+00:00

As we are now passing the filter data as pointers to the drivers, we can take the final step and also pass the filter function the same way. I'm keeping this change separate, as there it's less obvious that this is a net win. Upsides of this are: - The ASoC drivers are completely independent from the DMA engine implementation, which simplifies the Kconfig logic and in theory allows the same sound drivers to be built in a kernel that supports different kinds of dmaengine drivers. - Consistency with other subsystems and drivers On the other hand, we have a few downsides: - The s3c24xx-dma driver now needs to be built-in for the ac97 platform device to be instantiated on s3c2440. - samsung_dmaengine_pcm_config cannot be marked 'const' any more because the filter function pointer needs to be set at runtime. This is safe as long we don't have multiple different DMA engines in thet same system at runtime, but is nonetheless ugly.
