[alsa-devel] [PATCH] ASoC: rt286: fix headphone click/crack noise on Dell XPS 9343 I2S mode
by Kai-Heng Feng 13 Mar '17

13 Mar '17

HDA mode does not have these issues because necessary workarounds in linux/sound/pci/hda/patch_realtek.c are already applied. So we can leverage these workaournds into rt286. When jack is plugged, it rapidly generates I2C interrupts, which triggers rt286_irq() and rt286_jack_detect(), which causes the noise. alc_fixup_dell_xps13() in patch_realtek.c sets up a pin that can stop the frantic interrupts, hence fixes the click noise. When rt286 is under powersaving state, play a sound with headphone or plug a headphone in will produce a loud crack sound. alc_shutup_dell_xps13() patch_realtek.c mutes the headphone at plugging. Apply the same workaround to LDO2 power event can make the loud crack sound to a more tolerable pop sound. I found that unconditionally apply the workaround to all related power event can help a little further.

[alsa-devel] New platform CherryTrail/ES8316 audio output is silent
by Daniel Drake 20 Feb '17

20 Feb '17

Hi, I'm trying to get audio working on the Weibu F3C miniPC which has a 3.5mm headphone jack and 3.5mm mic jack. The SoC is Intel Cherry Trail x5-Z8300. The ES8316 codec included is not supported by Linux at the moment. I'd like to fix that and upstream the driver but so far am I stuck with no audio output, only silence. I do have a working Windows setup that I can poke at for more info. I would appreciate any suggestions or ideas. Here is a description of my efforts so far, followed by the work in progress code: I started with the Cherry Trail ES8316 platform driver + ES8316 codec driver which I found in https://github.com/JideTechnology/remixos-kernel/tree/jide_chuwi_vi10_plus_… First I did the required updates to get it building on Linux 4.9 including adding the driver for the codec's MCLK input which is done with some patches currently under review: clk: x86: Add Atom PMC platform clocks arch/x86/platform/atom: Move pmc_atom to drivers/platform/x86 platform/x86: Enable Atom PMC platform clocks I confirmed that I am manipulating the right clock by disabling it under Windows and observing that audio output suddenly stops. I created an audio loop within the codec itself, by enabling MIC1 as an input to the Left HP Mux, enabling the LLIN Switch, and enabling Left HP Mux as an input to Left Hp Mixer. Now when I make noise in the microphone, I can hear it on the headphone. This verifies that most of the audio path through the codec is working fine, and also that it is clocked. I used asoc debugfs to trace the path through the DAI, platform and codec DAPM graphs. Everything is On and active as expected. I confirmed that it is basically the same as another Cherry Trail platform I have here (except for the codec which is rt5645 on the other platform), including mixer levels. I also dumped the codec registers over I2C from Windows and set them to the exact same values on Linux. Still not working. At this point I am suspecting that this is likely a problem with the audio interface and its linkage to the codec (SSP/I2S). I modified the platform driver to use ssp1 instead of ssp2, because the device schematics say that I2S_1 is being used. Then I ran into send_ssp_cmd() complaining that ssp1 is not supported, and found a point of curiosity here. This code is basically to set the value of sst_cmd_sba_hw_set_ssp.selection which is documented as: /* 0:SSP0(def), 1:SSP1, 2:SSP2 */ But other platforms like cht_bsw_rt5645 use ssp2, for which send_ssp_cmd() will use SSP_CODEC, which has value 3. So it looks like the above comment is wrong? Either way, I tried selection values 0, 1, 2, and 3, and still no audio output. Here's the code, apologies that it is a bit unclean, I'll continue improving it once I get something working. Any suggestions, or do I need to get a hardware scope to diganose further? --- drivers/base/regmap/regmap-debugfs.c | 2 +- sound/soc/codecs/Kconfig | 4 + sound/soc/codecs/Makefile | 2 + sound/soc/codecs/es8316.c | 1386 ++++++++++++++++++++++++++++ sound/soc/codecs/es8316.h | 124 +++ sound/soc/intel/Kconfig | 12 + sound/soc/intel/atom/sst-atom-controls.c | 5 +- sound/soc/intel/atom/sst/sst_acpi.c | 2 + sound/soc/intel/boards/Makefile | 2 + sound/soc/intel/boards/cht_es8316.c | 1462 ++++++++++++++++++++++++++++++ 10 files changed, 2999 insertions(+), 2 deletions(-) create mode 100644 sound/soc/codecs/es8316.c create mode 100644 sound/soc/codecs/es8316.h create mode 100644 sound/soc/intel/boards/cht_es8316.c diff --git a/drivers/base/regmap/regmap-debugfs.c b/drivers/base/regmap/regmap-debugfs.c index 36ce351..6d3dc14 100644 --- a/drivers/base/regmap/regmap-debugfs.c +++ b/drivers/base/regmap/regmap-debugfs.c @@ -269,7 +269,7 @@ static ssize_t regmap_map_read_file(struct file *file, char __user *user_buf, count, ppos);

[alsa-devel] [PATCH v2 0/6] Move dell-led to drivers/platform/x86
by Michał Kępień 16 Feb '17

16 Feb '17

This patch series moves the dell-led driver from the LED subsystem to the x86 platform driver subsystem. The original motivation behind this effort was to move all code using the dell-smbios module to the x86 platform driver subsystem. While I was investigating the possibilities to do that, it quickly emerged that dell-led can and in fact should be moved to the x86 platform driver subsystem in its entirety. dell-led consists of two major parts: - the part exposing a microphone mute LED interface, introduced in db6d8cc00773 ("dell-led: add mic mute led interface"); this interface is used by sound/pci/hda/dell_wmi_helper.c; while the original implementation used a WMI interface, it was changed to use dell-smbios in cf0d7ea33596 ("dell-led: use dell_smbios_find_token() for finding mic DMI tokens") and 0c41a08e131d ("dell-led: use dell_smbios_send_request() for performing SMBIOS calls"), - the part handling an activity LED present in Dell Latitude 2100 netbooks, introduced in 72dcd8d08aca ("leds: Add Dell Business Class Netbook LED driver"); it binds to a specific WMI GUID and then registers a LED device which is controlled using WMI (i.e. it is essentially a WMI driver). Patches 1 and 2 clean up the microphone mute LED interface to minimize the amount of code moved around. Patch 3 updates a variable name in sound/pci/hda/dell_wmi_helper.c so that it better matches that variable's role. Patch 4 moves the microphone mute LED interface to drivers/platform/x86/dell-laptop.c, effectively causing sound/pci/hda/dell_wmi_helper.c to depend on CONFIG_DELL_LAPTOP instead of CONFIG_LEDS_DELL_NETBOOKS. Patch 5 reverts dell-led to the state it was in after its initial commit 72dcd8d08aca ("leds: Add Dell Business Class Netbook LED driver") by removing all remnants of the microphone mute LED handling code. Patch 6 moves all that is left of dell-led (i.e. the activity LED part, as originally implemented), to a new module which is placed in drivers/platform/x86/dell-wmi-led.c. As all patches except patch 3 in this series affect the LED subsystem, the series is based on linux-leds/for-4.11. Anthony, I would be grateful if you could test this patch series on the Dell machines you have access to that were previously supported by dell-led as Jacek needs a Tested-by from someone to sign off on these changes. Please note the Kconfig option rename done by the last patch. Thanks! Changes from v1: - Squash patches 2-4 from v1 into a single patch (#2 in v2). - Add patch 3. - Fix subject pattern in patch 4. - Slight commit message adjustments, including fixing a typo ("COFIG_LEDS_DELL_NETBOOKS") in patch 6. - Remove the name of the module's source file from the header comment in drivers/platform/x86/dell-wmi-led.c to avoid the need to update it in the future. drivers/leds/Kconfig | 9 --- drivers/leds/Makefile | 1 - drivers/platform/x86/Kconfig | 8 +++ drivers/platform/x86/Makefile | 1 + drivers/platform/x86/dell-laptop.c | 28 ++++++++ .../dell-led.c => platform/x86/dell-wmi-led.c} | 75 ++-------------------- include/linux/dell-led.h | 6 +- sound/pci/hda/dell_wmi_helper.c | 30 ++++----- 8 files changed, 60 insertions(+), 98 deletions(-) rename drivers/{leds/dell-led.c => platform/x86/dell-wmi-led.c} (73%) -- 2.11.0

[alsa-devel] [PATCH v7 0/4] DMA Engine: switch PL330 driver to non-irq-safe runtime PM
by Marek Szyprowski 09 Feb '17

09 Feb '17

Hello, This patchset changes the way the runtime PM is implemented in the PL330 DMA engine driver. The main goal of such change is to add support for the audio power domain to Exynos5 SoCs (5250, 542x, 5433, probably others) and let it to be properly turned off, when no audio is being used. Switching to non-irq-safe runtime PM is required to properly let power domain to be turned off (irq-safe runtime PM keeps power domain turned on all the time) and to integrate with clock controller's runtime PM (this cannot be workarounded any other way, PL330 uses clocks from the controller, which belongs to the same power domain). For more details of the proposed change to the PL330 driver see patch #4. Audio power domain on Exynos5 SoCs contains following hardware modules: 1. clock controller 2. pin controller 3. PL330 DMA controller 4. I2S audio controller Patches for adding or fixing runtime PM for each of the above devices is handled separately. Runtime PM patches for clock controllers is possible and has been proposed in the following thread (pending review): "[PATCH v4 0/4] Add runtime PM support for clocks (on Exynos SoC example)", http://www.spinics.net/lists/arm-kernel/msg550747.html Runtime PM support for Exynos pin controller has been posted in the following thread: "[PATCH 0/9] Runtime PM for Exynos pin controller driver", http://www.spinics.net/lists/arm-kernel/msg550161.html Exynos I2S driver supports runtime PM, but some fixes were needed for it and they are already queued to linux-next. This patchset is based on linux-next from 25th January 2017 with "dmaengine: pl330: fix double lock" patch applied. Best regards Marek Szyprowski Samsung R&D Institute Poland Changelog: v7: - added missing of_dma_request_slave_channel API change to sound/soc/sh/rcar driver - extended commit message with information about drawbacks of irq-safe runtime pm - added Ulf's reviewed-by tags v6: https://www.spinics.net/lists/arm-kernel/msg557377.html - fixed pl330 system sleep suspend/resume callbacks, previous implementation incorrectly tried to unprepare clocks unconditionally - after a fix pl330 suspend/resume callbacks can be simply replaced by generic pm_runtime_force_{suspend,resume} helpers, what simplifies code even more v5: https://www.spinics.net/lists/arm-kernel/msg555001.html - added Acks - additional mutex is indeed not needed, rely on dma_list_mutex in dmaengine core, added comment about locking v4: http://www.spinics.net/lists/dmaengine/msg12329.html - rebased onto "dmaengine: pl330: fix double lock" patch: http://www.spinics.net/lists/dmaengine/msg12289.html - added a mutex to protect runtime PM links creation/removal to avoid races - moved mem2mem channel case handing to pl330_{add,del}_slave_pm_link functions to simplify code and error paths v3: http://www.spinics.net/lists/dmaengine/msg12245.html - removed pl330_filter function as suggested by Arnd Bergmann - removed pl330.h from arch/arm/plat-samsung/devs.c - fixes some minor style issues pointed by Krzysztof Kozlowski v2: https://www.spinics.net/lists/arm-kernel/msg552772.html - rebased onto linux next-20170109 - improved patch description - separated patch #3 from #4 (storing a pointer to slave device for each DMA channel) as requested by Krzysztof Kozlowski v1: https://www.spinics.net/lists/arm-kernel/msg550008.html - initial version Patch summary: Marek Szyprowski (4): dmaengine: pl330: remove pdata based initialization dmaengine: Forward slave device pointer to of_xlate callback dmaengine: pl330: Store pointer to slave device dmaengine: pl330: Don't require irq-safe runtime PM arch/arm/plat-samsung/devs.c | 1 - drivers/dma/amba-pl08x.c | 2 +- drivers/dma/at_hdmac.c | 4 +- drivers/dma/at_xdmac.c | 2 +- drivers/dma/bcm2835-dma.c | 2 +- drivers/dma/coh901318.c | 2 +- drivers/dma/cppi41.c | 2 +- drivers/dma/dma-jz4780.c | 2 +- drivers/dma/dmaengine.c | 2 +- drivers/dma/dw/platform.c | 2 +- drivers/dma/edma.c | 4 +- drivers/dma/fsl-edma.c | 2 +- drivers/dma/img-mdc-dma.c | 2 +- drivers/dma/imx-dma.c | 2 +- drivers/dma/imx-sdma.c | 2 +- drivers/dma/k3dma.c | 2 +- drivers/dma/lpc18xx-dmamux.c | 2 +- drivers/dma/mmp_pdma.c | 2 +- drivers/dma/mmp_tdma.c | 2 +- drivers/dma/moxart-dma.c | 2 +- drivers/dma/mxs-dma.c | 2 +- drivers/dma/nbpfaxi.c | 2 +- drivers/dma/of-dma.c | 19 ++-- drivers/dma/pl330.c | 220 ++++++++++++++++------------------------ drivers/dma/pxa_dma.c | 2 +- drivers/dma/qcom/bam_dma.c | 2 +- drivers/dma/sh/rcar-dmac.c | 2 +- drivers/dma/sh/shdma-of.c | 2 +- drivers/dma/sh/usb-dmac.c | 2 +- drivers/dma/sirf-dma.c | 2 +- drivers/dma/st_fdma.c | 2 +- drivers/dma/ste_dma40.c | 2 +- drivers/dma/stm32-dma.c | 2 +- drivers/dma/sun4i-dma.c | 2 +- drivers/dma/sun6i-dma.c | 2 +- drivers/dma/tegra20-apb-dma.c | 2 +- drivers/dma/tegra210-adma.c | 2 +- drivers/dma/xilinx/xilinx_dma.c | 2 +- drivers/dma/xilinx/zynqmp_dma.c | 2 +- drivers/dma/zx_dma.c | 2 +- include/linux/amba/pl330.h | 35 ------- include/linux/of_dma.h | 19 ++-- sound/soc/sh/rcar/dma.c | 5 +- sound/soc/sh/rcar/dvc.c | 3 +- sound/soc/sh/rcar/rsnd.h | 3 +- sound/soc/sh/rcar/src.c | 3 +- sound/soc/sh/rcar/ssi.c | 3 +- 47 files changed, 158 insertions(+), 231 deletions(-) delete mode 100644 include/linux/amba/pl330.h -- 1.9.1

[alsa-devel] [RFC 00/16] ASoC: hdac_hdmi: Add Support to Enable MST Audio
by jeeja.kp＠intel.com 08 Feb '17

08 Feb '17

From: Jeeja KP <jeeja.kp(a)intel.com> Display port 1.2 introduces new capability Multi-stream transport (MST) which will allow multiple stream to route to single display port where multiple monitors are connected. Multiple monitors will be connected by a MST Hub or a monitor capable of daisy-chaining. With MST support, a pin can support multiple ports and on each port a monitor can be connected. This patch series enables DP MST Audio by extending the current design from pin to port. 1. With MST, Pin mux for CVT selection will be used to select CVT for Pin-port instead of Pin. So create the pin muxes accordingly. 2. Pin is marked as MST capable when connect event reports pipe as valid. if pipe is -1, then pin is not MST capable and default to port 0. if pipe is valid, then pin is MST capable and port = pipe. 3. For MST capable pin, select the device entry before configuring the pin widget verbs controlling the sink device operations. 4. Add support to handle multiple Port mapped to same converter by enabling all the ports and configuring the port when stream is prepared. 5. i915 acomp APIs are now used to read the ELD info and support is extended for MST port as well Notes: 1. When Mutiple ports are mapped to same PCM, currenlty stream constrains will applied based on first port mapped.
