2020-11-24soc/intel/skylake: Support NHLT 1ch DMICBenjamin Doron
Allows advertising support for a 1ch array DMIC in the NHLT table. Boards use the NHLT if a microphone is connected to the DSP. Tested on an Acer Aspire VN7-572G (Skylake-U) on Windows 10. A custom ALSA topology will be required for Linux.

2020-11-24soc/intel/skylake: Use correct NHLT_PDM_DEV definitionBenjamin Doron
According to the NHLT specification[1], PDM_DEV is defined as "1" on Kabylake based platforms. coreboot currently sets it to "0" on all platforms. Add an entry to the enum and use it to define NHLT_PDM_DEV for Kabylake. "Device Type" will resume from "2" on all platforms, but entries are currently reserved. Tested on an Acer Aspire VN7-572G (Skylake-U), which has a 1ch array DMIC, on Windows 10. 1. https://01.org/sites/default/files/595976_intel_sst_nhlt.pdf Change-Id: Ifbc67228c9e7af7db5154d597ca8d67860cfd2ed Signed-off-by: Benjamin Doron <benjamin.doron00@gmail.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/45010 Reviewed-by: Angel Pons <th3fanbus@gmail.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>

2020-03-18soc: Remove copyright noticesPatrick Georgi
They're listed in AUTHORS and often incorrect anyway, for example: - What's a "Copyright $year-present"? - Which incarnation of Google (Inc, LLC, ...) is the current copyright holder? - People sometimes have their editor auto-add themselves to files even though they only deleted stuff - Or they let the editor automatically update the copyright year, because why not? - Who is the copyright holder "The coreboot project Authors"? - Or "Generated Code"? Sidestep all these issues by simply not putting these notices in individual files, let's list all copyright holders in AUTHORS instead and use the git history to deal with the rest.

2016-01-16intel/skylake: Fix uninitialized variable warningMartin Roth
I don't think the warning is valid, because we already verify that num_channels is 2 or 4 as soon as we enter the function. Adding the default case makes the compiler happy. Fixes warning: src/soc/intel/skylake/nhlt/dmic.c: In function 'nhlt_soc_add_dmic_array': src/soc/intel/skylake/nhlt/dmic.c:100:2: error: 'formats' may be used uninitialized in this function [-Werror=maybe-uninitialized] return nhlt_endpoint_add_formats(endp, formats, num_formats); ^ Change-Id: Idc22c8478ff666af8915d780d7553909c3163690 Signed-off-by: Martin Roth <martinroth@google.com> Reviewed-on: https://review.coreboot.org/13021 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>
2016-01-15intel/skylake: add nhlt supportAaron Durbin
The use of a NHLT table is required to make audio work on the skylake SoCs employing the internal DSP. The table describes the audo endpoints (render vs capture) along with their supported formats. These formats are not only dependent on the audio peripheral but also hardware interfaces. As such each format has an associated blob of DSP settings to make the peripheral work. Lastly, each of these settings are provided by Intel and need to be generated for each device's hardware connection plus mode/format it supports. This patch does not include the dsp setting blobs. The current supported connections: - digital mic array 2 channel - digital mic array 4 channel - Maxim 98357 amplifier - ADI ssm4567 - NAU88L25 headset codec BUG=chrome-os-partner:44481 BRANCH=None TEST=Built glados. Speakers, headphones, and mic on camera decently worked.
