[PATCH v5] ASoC: cros_ec_codec: Reset I2S RX when probing
by Yu-Hsuan Hsu 13 Jan '21

13 Jan '21

It is not guaranteed that I2S RX is disabled when the kernel booting. For example, if the kernel crashes while it is enabled, it will keep enabled until the next time EC reboots. Reset I2S RX when probing to fix this issue. Signed-off-by: Yu-Hsuan Hsu <yuhsuan(a)chromium.org> --- This patch checks the return value. If it is -ENOPROTOOPT (EC_RES_INVALID_VERSION), it will ask clients to update EC firmware.

[PATCH v2 0/7] PinePhone BT audio bringup
by Samuel Holland 13 Jan '21

13 Jan '21

This series makes use of the additional DAIs recently added to the sun8i-codec driver to add hardware routing for BT SCO (headset) audio on the PinePhone. The BT audio connection is represented by the "dummy" bt-sco codec. The connection to the Quectel EG-25G modem via AIF2 works as well, but I do not include it here because there is no appropriate codec driver in tree. We have been using an out-of-tree "dummy" codec driver for the modem similar to bt-sco, and I'm not sure if such a driver would be desired upstream.

[PATCH v2 2/2] ASoC: rt715:add Mic Mute LED control support
by Perry Yuan 13 Jan '21

13 Jan '21

From: Perry Yuan <perry_yuan(a)dell.com> Some new Dell system is going to support audio internal micphone privacy setting from hardware level with micmute led state changing When micmute hotkey pressed by user, soft mute will need to be enabled firstly in case of pop noise, and codec driver need to react to mic mute event to EC notifying that SW mute is completed. Then EC will do the HW mute physically. This patch allow codec rt715 driver to ack EC when micmute key pressed through this micphone led control interface like hda_generic provided.

[PATCH 00/10] Remove support for TX49xx
by Thomas Bogendoerfer 13 Jan '21

13 Jan '21

I couldn't find any buyable product other than reference boards using TX49xx CPUs. And since nobody showed interest in keeping support for it, it's time to remove it. I've split up the removal into seperate parts for different maintainers. So if the patch fits your needs, please take it via your tree or give me an ack so I can apply them the mips-next tree.

[PATCH] ALSA: hda: fix SND_INTEL_DSP_CONFIG dependency
by Arnd Bergmann 12 Jan '21

12 Jan '21

From: Arnd Bergmann <arnd(a)arndb.de> The sof-pci-dev driver fails to link when built into the kernel and CONFIG_SND_INTEL_DSP_CONFIG is set to =m: arm-linux-gnueabi-ld: sound/soc/sof/sof-pci-dev.o: in function `sof_pci_probe': sof-pci-dev.c:(.text+0x1c): undefined reference to `snd_intel_dsp_driver_probe' All other drivers using this interface already use a 'select SND_INTEL_DSP_CONFIG' statement to force the it to be present, so it seems reasonable to do the same here. The stub implementation in the header makes the problem harder to find, as it avoids the link error when SND_INTEL_DSP_CONFIG is completely disabled, without any obvious upsides. Remove these stubs to make it clearer that the driver is in fact needed here.

[PATCH v3 1/4] ALSA: hda/realtek: Power up codec when setting LED via COEF and GPIO
by Kai-Heng Feng 12 Jan '21

System takes a very long time to suspend after commit 215a22ed31a1 ("ALSA: hda: Refactor codec PM to use direct-complete optimization"): [ 90.065964] PM: suspend entry (s2idle) [ 90.067337] Filesystems sync: 0.001 seconds [ 90.185758] Freezing user space processes ...

However, led_suspend() for mute and micmute led writes codec register, triggers a pending wake up. The wakeup is then handled in __device_suspend() by the following: - pm_runtime_disable() to handle the wakeup event. - device is no longer is suspended state, direct-complete isn't taken. - pm_runtime_enable() to balance disable_depth. if (dev->power.direct_complete) { if (pm_runtime_status_suspended(dev)) { pm_runtime_disable(dev); if (pm_runtime_status_suspended(dev)) { pm_dev_dbg(dev, state, "direct-complete "); goto Complete; } pm_runtime_enable(dev); } dev->power.direct_complete = false; } Since direct-complete doens't apply anymore, the codec's system suspend routine is used. This doesn't play well with SOF driver. When its runtime resume is called for system suspend, hda_codec_jack_check() schedules jackpoll_work which uses snd_hdac_is_power_on() to check whether codec is suspended. Because of the previous pm_runtime_enable(), snd_hdac_is_power_on() returns false and jackpoll continues to run, and snd_hda_power_up_pm() cannot power up an already suspended codec in multiple attempts, causes the long delay on system suspend. When direct-complete path is taken, snd_hdac_is_power_on() returns true and hda_jackpoll_work() is skipped by accident. This is still not correct, and it will be addressed by later patch. Explicitly runtime resume codec on setting LED to solve the issue.

[PATCH v3 0/3] Dell hardware privacy implementation for dell laptop
by Perry Yuan 12 Jan '21

12 Jan '21

From: Perry Yuan <perry_yuan(a)dell.com> Hi All, This patch set is a new driver for dell mobile platform ,which has the hardware privacy feature. For micmute led control, the hotkey is Fn + F4, it is a hardware based mute state, and new privacy will prevent micphone void input from hardware layer, any application cannot get voice data when micmute activated. Camera mute use a new hardware design to control the camrea shutter. When video is muted, no OS application should be functionally able to capture images of the person/environment in front of the system Older history: [1]https://patchwork.kernel.org/project/platform-driver-x86/patch/2020122813… [2]https://patchwork.kernel.org/project/alsa-devel/patch/20201103125859.8759… [3]https://www.spinics.net/lists/alsa-devel/msg120537.html [4]https://github.com/thesofproject/linux/pull/2660 Perry Yuan (3): platform/x86: dell-privacy: Add support for Dell hardware privacy x86/platform/dell-privacy-wmi: add document for dell privacy driver ASoC: rt715:add micmute led state control supports .../testing/sysfs-platform-dell-privacy-wmi | 31 ++ drivers/platform/x86/Kconfig | 17 + drivers/platform/x86/Makefile | 4 +- drivers/platform/x86/dell-laptop.c | 25 +- drivers/platform/x86/dell-privacy-acpi.c | 167 +++++++++ drivers/platform/x86/dell-privacy-wmi.c | 320 ++++++++++++++++++ drivers/platform/x86/dell-privacy-wmi.h | 33 ++ drivers/platform/x86/dell-wmi.c | 37 +- sound/soc/codecs/rt715-sdca.c | 16 + sound/soc/codecs/rt715-sdca.h | 1 + sound/soc/codecs/rt715.c | 14 + sound/soc/codecs/rt715.h | 1 + 12 files changed, 650 insertions(+), 16 deletions(-) create mode 100644 Documentation/ABI/testing/sysfs-platform-dell-privacy-wmi create mode 100644 drivers/platform/x86/dell-privacy-acpi.c create mode 100644 drivers/platform/x86/dell-privacy-wmi.c create mode 100644 drivers/platform/x86/dell-privacy-wmi.h -- 2.25.1
