2016-06-29soc/intel/skylake: refactor nhlt supportAaron Durbin
Utilize the new NHLT helper functions by driving the NHLT endpoints through data descriptors.

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.
