[PATCH 0/7] Add I2S-MCC support for Microchip's SAMA7G5
by Codrin Ciubotariu 01 Mar '21

01 Mar '21

SAMA7G5 includes an updated version of I2S-MCC, found previously on SAM9X60. This controller includes 8 data pins, 4 for playback and 4 for capture. For I2S and LEFT_J formats, these pins can be used to send/receive up to 8 audio channels. For DSP_A, with TDM, any pins pair (DIN/DOUT) from these 4 can be selected to send/receive data. This version also includes 2 FIFOs (send and receive). This patch set starts by moving the driver's bindings to yaml and continues with adding a new compatible for the SAMA7G5 variant, followed by the changes needed for I2S/LEFT_J support, TDM pin pair selection and FIFO support, exclusively for SAMA7G5.

[PATCH] sound/usb generate midi streaming substream names from jack names
by George Harker 01 Mar '21

01 Mar '21

A number of devices have named substreams which are hard to remember / decypher from <device> MIDI n names. Eg. Korg puts a pass through on one substream and iConnectivity devices name the connections. This makes it easier to connect to the correct device. Devices which handle naming through quirks are unaffected by this change.

[PATCH v2] ALSA: hda/hdmi: let new platforms assign the pcm slot dynamically
by Hui Wang 01 Mar '21

01 Mar '21

If the platform set the dyn_pcm_assign to true, it will call hdmi_find_pcm_slot() to find a pcm slot when hdmi/dp monitor is connected and need to create a pcm. So far only intel_hsw_common_init() and patch_nvhdmi() set the dyn_pcm_assign to true, here we let tgl platforms assign the pcm slot dynamically first, if the driver runs for a period of time and there is no regression reported, we could set no_fixed_assgin to true in the intel_hsw_common_init(), and then set it to true in the patch_nvhdmi(). This change comes from the discussion between Takashi and Kai Vehmanen. Please refer to: https://github.com/alsa-project/alsa-lib/pull/118 Signed-off-by: Hui Wang <hui.wang(a)canonical.com> --- Did the test with this patch on 2 TGL machines, and with both legacy HDA driver and sof driver, plug 1 monitor into the machine, plug 2 monitors into the machine and plug 2 monitors into a dp-mst hub, they all worked as expcted, the first 2 pcm slots was assigned to monitors, and playback worked well. sound/pci/hda/patch_hdmi.c | 18 +++++++++++++++++- 1 file changed, 17 insertions(+), 1 deletion(-) diff --git a/sound/pci/hda/patch_hdmi.c b/sound/pci/hda/patch_hdmi.c index 97adff0cbcab..1aca815b920d 100644 --- a/sound/pci/hda/patch_hdmi.c +++ b/sound/pci/hda/patch_hdmi.c @@ -157,6 +157,7 @@ struct hdmi_spec { bool dyn_pin_out; bool dyn_pcm_assign; + bool no_fixed_assign; bool intel_hsw_fixup; /* apply Intel platform-specific fixups */ /* * Non-generic VIA/NVIDIA specific @@ -1345,6 +1346,12 @@ static int hdmi_find_pcm_slot(struct hdmi_spec *spec, { int i; + /* on the new machines, try to assign the pcm slot dynamically, + * not use the preferred fixed map anymore. + */ + if (spec->no_fixed_assign) + goto last_try; + /* * generic_hdmi_build_pcms() may allocate extra PCMs on some * platforms (with maximum of 'num_nids + dev_num - 1') @@ -1374,6 +1381,7 @@ static int hdmi_find_pcm_slot(struct hdmi_spec *spec, return i; } + last_try: /* the last try; check the empty slots in pins */ for (i = 0; i < spec->num_nids; i++) { if (!test_bit(i, &spec->pcm_bitmap)) @@ -2988,8 +2996,16 @@ static int patch_i915_tgl_hdmi(struct hda_codec *codec) * the index indicate the port number. */ static const int map[] = {0x4, 0x6, 0x8, 0xa, 0xb, 0xc, 0xd, 0xe, 0xf}; + int ret; - return intel_hsw_common_init(codec, 0x02, map, ARRAY_SIZE(map)); + ret = intel_hsw_common_init(codec, 0x02, map, ARRAY_SIZE(map)); + if (!ret) { + struct hdmi_spec *spec = codec->spec; + + spec->no_fixed_assign = true; + } + + return ret; } /* Intel Baytrail and Braswell; with eld notifier */ -- 2.25.1

Turning an external amplifier on or off when audio is played
by Amr Bekhit 28 Feb '21

28 Feb '21

Hello, I'm working with an embedded system that uses the SGTL5000 to play audio. We have an amplifier connected to the DAC output, which we can turn off using a GPIO pin. I'd like to automatically enable the amplifier before playing a sound and disable it after playback has completed. Are there any hooks that would allow me to do that in userspace? If not, is there something in kernel-space that would allow me to accomplish this? Thanks, Amr
