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

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 ... (elapsed 0.002 seconds) done. [ 90.188713] OOM killer disabled. [ 90.188714] Freezing remaining freezable tasks ... (elapsed 0.001 seconds) done. [ 90.190024] printk: Suspending console(s) (use no_console_suspend to debug) [ 90.904912] intel_pch_thermal 0000:00:12.0: CPU-PCH is cool [49C], continue to suspend [ 321.262505] snd_hda_codec_realtek ehdaudio0D0: Unable to sync register 0x2b8000. -5 [ 328.426919] snd_hda_codec_realtek ehdaudio0D0: Unable to sync register 0x2b8000. -5 [ 329.490933] ACPI: EC: interrupt blocked That commit keeps the codec suspended during the system suspend. 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.

[PATCH] ASoC: es8316: Fix possible NULL pointer deref in es8316_disable_jack_detect()
by Hans de Goede 12 Jan '21

12 Jan '21

sound/soc/soc-core.c: soc_remove_component() unconditionally calls snd_soc_component_set_jack(component, NULL, NULL); on any components being removed. This means that on machines where the machine-driver does not provide a jack through snd_soc_component_set_jack() es8316_disable_jack_detect() will still get called and at this time es8316->jack will be NULL and the es8316->jack->status check in es8316_disable_jack_detect() will lead to a NULL pointer deref. Fix this by checking for es8316->jack bein NULL at the start of es8316_disable_jack_detect() and turn the function into a no-op in that case.

[PATCH 0/3] ASoC: Intel: bytcr_rt5640: Add support for devices with only a headphone jack (no speakers/mic)
by Hans de Goede 12 Jan '21

12 Jan '21

Hi All, This series adds support for devices with only a headphone jack (no speakers/internal mic). Specifically this adds support for the Mele PCG03 Mini PC. But the new no-speakers and no-internal-mic quirks will likely be useful on other devices too. Regards, Hans

[PATCH] ASoC: Intel: cht_bsw_nau8824: Move snd_soc_dai_set_tdm_slot call to cht_codec_fixup
by Hans de Goede 12 Jan '21

12 Jan '21

Move the snd_soc_dai_set_tdm_slot() call from cht_codec_init() to cht_codec_fixup(). There are 2 reasons for doing this: 1. This aligns the cht_bsw_nau8824 with all the other BYT/CHT machine drivers which also do this from their codec_fixup function. 2. When using the SOF driver, things like the TDM info is set from the topology file. Moving the call to the codec_fixup function, which gets skipped when using the SOF driver avoids the call interfering with the settings when using the SOF driver.

[PATCH v2 0/2] fix tegra-hda on tegra30 devices
by Peter Geis 12 Jan '21

12 Jan '21

The following patches fix tegra-hda on legacy tegra devices. Two issues were discovered preventing tegra-hda from functioning: -The hda clocks on tegra30 were assigned to clk_m and running at too low of a rate to function. -The tegra-hda encounters an input/output error when opening a stream. Since the only mainline device that used tegra-hda until recently was the t124, it is unknown exactly when this was broken. Fortunately a recent patch was submitted that fixed the issue only on t194 devices. We can apply it to the tegra30-hda device to resolve the issue across the board. Note that downstream devices used the spdif device instead of hda for hdmi audio. The spdif device lacks a driver on mainline. -Checkpatch seems to have issues finding [1], but git show has no issue.
