From 35446d5551934e313c1eed15459430a3fe1a9a34 Mon Sep 17 00:00:00 2001 From: Jianeng Ceng Date: Fri, 19 Jan 2024 09:40:50 +0800 Subject: [PATCH] mb/google/nissa/var/anraggar: Enable BT audio offload This patch enables Cnvi BT Audio Offload feature and also configures the virtual GPIO for CNVi Bluetooth I2S pads. BUG=b:303157827 TEST=Build and boot to anraggar. Verify the config from serial logs. w/o this CL - ``` [SPEW ] -- CNVi Config -- [SPEW ] CNVi Mode= 1 [SPEW ] Wi-Fi Core= 1 [SPEW ] BT Core= 1 [SPEW ] BT Audio Offload= 0 [SPEW ] Pin Muxing ``` w/ this CL - ``` [SPEW ] -- CNVi Config -- [SPEW ] CNVi Mode= 1 [SPEW ] Wi-Fi Core= 1 [SPEW ] BT Core= 1 [SPEW ] BT Audio Offload= 1 [SPEW ] Pin Muxing ``` Change-Id: I9e6731c8ceaad6ee58b525d4246fa769bfe1b0c7 Signed-off-by: Jianeng Ceng Reviewed-on: https://review.coreboot.org/c/coreboot/+/80001 Reviewed-by: Weimin Wu Reviewed-by: Eric Lai Reviewed-by: Subrata Banik Tested-by: build bot (Jenkins) --- .../google/brya/variants/anraggar/gpio.c | 18 ++++++++++++++++++ .../brya/variants/anraggar/overridetree.cb | 3 +++ 2 files changed, 21 insertions(+) diff --git a/src/mainboard/google/brya/variants/anraggar/gpio.c b/src/mainboard/google/brya/variants/anraggar/gpio.c index 8e0b76b778..8bc3f6b351 100644 --- a/src/mainboard/google/brya/variants/anraggar/gpio.c +++ b/src/mainboard/google/brya/variants/anraggar/gpio.c @@ -69,6 +69,24 @@ static const struct pad_config override_gpio_table[] = { PAD_NC_LOCK(GPP_R6, NONE, LOCK_CONFIG), /* R7 : DMIC_DATA_1A ==> NC */ PAD_NC_LOCK(GPP_R7, NONE, LOCK_CONFIG), + + /* Configure the virtual CNVi Bluetooth I2S GPIO pads */ + /* BT_I2S_BCLK */ + PAD_CFG_NF(GPP_VGPIO_30, NONE, DEEP, NF3), + /* BT_I2S_SYNC */ + PAD_CFG_NF(GPP_VGPIO_31, NONE, DEEP, NF3), + /* BT_I2S_SDO */ + PAD_CFG_NF(GPP_VGPIO_32, NONE, DEEP, NF3), + /* BT_I2S_SDI */ + PAD_CFG_NF(GPP_VGPIO_33, NONE, DEEP, NF3), + /* SSP2_SCLK */ + PAD_CFG_NF(GPP_VGPIO_34, NONE, DEEP, NF1), + /* SSP2_SFRM */ + PAD_CFG_NF(GPP_VGPIO_35, NONE, DEEP, NF1), + /* SSP_TXD */ + PAD_CFG_NF(GPP_VGPIO_36, NONE, DEEP, NF1), + /* SSP_RXD */ + PAD_CFG_NF(GPP_VGPIO_37, NONE, DEEP, NF1), }; /* Early pad configuration in bootblock */ diff --git a/src/mainboard/google/brya/variants/anraggar/overridetree.cb b/src/mainboard/google/brya/variants/anraggar/overridetree.cb index ca9c655194..9646f29a60 100644 --- a/src/mainboard/google/brya/variants/anraggar/overridetree.cb +++ b/src/mainboard/google/brya/variants/anraggar/overridetree.cb @@ -81,6 +81,9 @@ chip soc/intel/alderlake .configure_ext_fivr = 0, }" + # Enable the Cnvi BT Audio Offload + register "cnvi_bt_audio_offload" = "1" + # Intel Common SoC Config #+-------------+------------------------------+ #| Field | Value |
