Before 160ms After 460ms(met spec min=400ms) BUG=b:295277868 TEST=emerge coreboot EE measured power sequence met spec boot to system and check wifi connection is fine Change-Id: Ifb909a55b36f2366132c3e20021c4bde4bc87a05 Signed-off-by: Tony Huang Reviewed-on: https://review.coreboot.org/c/coreboot/+/77117 Tested-by: build bot (Jenkins) Reviewed-by: Derek Huang --- src/mainboard/google/brya/variants/yavilla/gpio.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/mainboard/google/brya/variants/yavilla/gpio.c b/src/mainboard/google/brya/variants/yavilla/gpio.c index fb7577f06c..d33e588ce3 100644 --- a/src/mainboard/google/brya/variants/yavilla/gpio.c +++ b/src/mainboard/google/brya/variants/yavilla/gpio.c @@ -52,7 +52,7 @@ static const struct pad_config early_gpio_table[] = { /* D6 : WWAN_EN */ PAD_CFG_GPO(GPP_D6, 0, DEEP), /* H20 : IMGCLKOUT1 ==> WLAN_PERST_L */ - PAD_CFG_GPO(GPP_H20, 0, DEEP), + PAD_CFG_GPO(GPP_H20, 1, DEEP), /* A13 : GPP_A13 ==> GSC_SOC_INT_ODL */ PAD_CFG_GPI_APIC(GPP_A13, NONE, PLTRST, LEVEL, INVERT), /* E12 : THC0_SPI1_IO1 ==> SOC_WP_OD */
