From 83670c517694de4803e5bf00348e303092155326 Mon Sep 17 00:00:00 2001 From: Naveen Manohar Date: Sat, 4 Nov 2017 02:55:09 +0530 Subject: soc/intel/kabylake: Add Dialog da7219 NHLT blob support Add APIs and required parameters for creating Dialog da7219 SSP endpoints in NHLT table. The use of a NHLT table is required to make audio work on the kabylake SoCs employing the internal DSP. The table describes the audio endpoints (render vs capture) along with their supported formats. BUG=b:68686020 TEST=check that NHLT table for da7219 is created properly Change-Id: I57b88873f1c59c8aadf8eec3c80a9d95165a2cc3 Signed-off-by: Naveen Manohar Signed-off-by: Rizwan Qureshi Reviewed-on: https://review.coreboot.org/22324 Tested-by: build bot (Jenkins) Reviewed-by: Furquan Shaikh --- src/soc/intel/skylake/Kconfig | 6 +++ src/soc/intel/skylake/include/soc/nhlt.h | 6 +++ src/soc/intel/skylake/nhlt/Makefile.inc | 6 +++ src/soc/intel/skylake/nhlt/da7219.c | 69 ++++++++++++++++++++++++++++++++ 4 files changed, 87 insertions(+) create mode 100644 src/soc/intel/skylake/nhlt/da7219.c (limited to 'src/soc/intel/skylake') diff --git a/src/soc/intel/skylake/Kconfig b/src/soc/intel/skylake/Kconfig index f830f540d5..f9431701a1 100644 --- a/src/soc/intel/skylake/Kconfig +++ b/src/soc/intel/skylake/Kconfig @@ -272,6 +272,12 @@ config NHLT_MAX98927 help Include DSP firmware settings for max98927 amplifier. +config NHLT_DA7219 + bool + default n + help + Include DSP firmware settings for DA7219 headset codec. + choice prompt "Cache-as-ram implementation" default CAR_NEM_ENHANCED diff --git a/src/soc/intel/skylake/include/soc/nhlt.h b/src/soc/intel/skylake/include/soc/nhlt.h index d3e4568d29..1af27e8d5c 100644 --- a/src/soc/intel/skylake/include/soc/nhlt.h +++ b/src/soc/intel/skylake/include/soc/nhlt.h @@ -77,4 +77,10 @@ int nhlt_soc_add_rt5663(struct nhlt *nhlt, int hwlink); */ int nhlt_soc_add_max98927(struct nhlt *nhlt, int hwlink); +/* + * Add da7219 headset codec on provided SSP link.
