From aa832c19b2c3e4f1be6b917abd962a7d664be7a3 Mon Sep 17 00:00:00 2001 From: Maulik V Vaghela Date: Fri, 27 Mar 2020 17:38:15 +0530 Subject: mb/intel/jasperlake_rvp: Configure WWAN GPIOs M.2 WWAN interface has GPIOs which requires coreboot to configure all related GPIOs as per board schematics. BUG=None BRANCH=None TEST=code compiles and WWAN device is detected in OS Change-Id: I8ad978a619b50e16ad754177f1eb05cf7670b79f Signed-off-by: Maulik V Vaghela Reviewed-on: https://review.coreboot.org/c/coreboot/+/39877 Tested-by: build bot (Jenkins) Reviewed-by: Ronak Kanabar Reviewed-by: Aamir Bohra Reviewed-by: Subrata Banik --- .../intel/jasperlake_rvp/variants/jslrvp/gpio.c | 29 +++++++++++++++------- 1 file changed, 20 insertions(+), 9 deletions(-) (limited to 'src/mainboard') diff --git a/src/mainboard/intel/jasperlake_rvp/variants/jslrvp/gpio.c b/src/mainboard/intel/jasperlake_rvp/variants/jslrvp/gpio.c index 726417a8cc..744a299af9 100644 --- a/src/mainboard/intel/jasperlake_rvp/variants/jslrvp/gpio.c +++ b/src/mainboard/intel/jasperlake_rvp/variants/jslrvp/gpio.c @@ -9,7 +9,18 @@ static const struct pad_config gpio_table[] = { /* ToDo: Fill other gpio configuration */ - /* Audio related GPIOs */ + /* WWAN_WAKE_N */ + PAD_CFG_GPI_SCI(GPP_A10, NONE, DEEP, LEVEL, INVERT), + + /* M.2_WWAN_DISABLE_N */ + PAD_CFG_GPO(GPP_A19, 1, PLTRST), + + /* WWAN_PERST_N */ + PAD_CFG_GPO(GPP_C0, 0, PLTRST), + + /* M2_WWAN_SSD_SKT2_CFG2 */ + PAD_CFG_GPI(GPP_C3, NONE, PLTRST), + /* I2C0_SDA */ PAD_CFG_NF(GPP_C16, UP_2K, DEEP, NF1), @@ -19,14 +30,11 @@ static const struct pad_config gpio_table[] = { /* I2S_MCLK */ PAD_CFG_NF(GPP_D18, NONE, DEEP, NF1), - /* SD_CD# */ - PAD_CFG_NF(GPP_G5, UP_20K, PWROK, NF1), - - /* SD_WP */ - PAD_CFG_NF(GPP_G7, DN_20K, PWROK, NF1), + /* WWAN_FCP_OFF_N */ + PAD_CFG_GPO(GPP_E3, 1, PLTRST), - /* virtual GPIO for SD card detect */ - PAD_CFG_GPI_GPIO_DRIVER(VGPIO_39, NONE, DEEP), + /* WWAN EN GPIO */ + PAD_CFG_GPO(GPP_H7, 1, PLTRST), /* I2S1_SCLK */ PAD_CFG_NF(GPP_H15, NONE, DEEP, NF1), @@ -55,6 +63,9 @@ static const struct pad_config gpio_table[] = { /* I2S1_TXD */ PAD_CFG_NF(GPP_R7, NONE, DEEP, NF2), + /* WWAN RST_N */ + PAD_CFG_GPO(GPP_S0, 1, DEEP), + /* DMIC_CLK_1 */ PAD_CFG_NF(GPP_S2, UP_20K, DEEP, NF2), @@ -71,7 +82,7 @@ static const struct pad_config gpio_table[] = { /* Early pad configuration in bootblock */ static const struct pad_config early_gpio_table[] = { -/* ToDo: Fill early gpio configurations for TPM and WWAN */ + /* ToDo: Fill early gpio configurations for TPM */ }; const struct pad_config *variant_gpio_table(size_t *num) -- cgit v1.2.3
