From eba8952de13987ee070f914b2e84ffa97f414d7e Mon Sep 17 00:00:00 2001 From: Seunghwan Kim Date: Mon, 21 Aug 2023 14:23:15 +0900 Subject: mb/google/nissa/var/pirrha: Use GpioInt instead of GPE for digitizer pen Currently pirrha's digitizer pen uses GPP_F12 for I2C HID interrupt signal. But its IRQ number is the same as GPD2, which is used as EC_SYNC_IRQ. It caused EC driver loading error from dmesg: cros_ec_lpcs GOOG0004:00: Failed to request IRQ 98: -16 cros_ec_lpcs GOOG0004:00: couldn't register ec_dev (-16) cros_ec_lpcs: probe of GOOG0004:00 failed with error -16 So change the digitizer pen interrupt type to GpioInt to prevent the conflict. BUG=b:292134655 TEST=Verified EC driver reported no error and pen device worked Change-Id: Ieb88e87fcfb06544a4b5b5133b752aa821fab76a Signed-off-by: Seunghwan Kim Reviewed-on: https://review.coreboot.org/c/coreboot/+/77346 Reviewed-by: Paul Menzel Reviewed-by: Martin L Roth Tested-by: build bot (Jenkins) --- src/mainboard/google/brya/variants/pirrha/gpio.c | 2 +- src/mainboard/google/brya/variants/pirrha/overridetree.cb | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) (limited to 'src/mainboard') diff --git a/src/mainboard/google/brya/variants/pirrha/gpio.c b/src/mainboard/google/brya/variants/pirrha/gpio.c index d0a114fe3c..431b613c0a 100644 --- a/src/mainboard/google/brya/variants/pirrha/gpio.c +++ b/src/mainboard/google/brya/variants/pirrha/gpio.c @@ -36,7 +36,7 @@ static const struct pad_config override_gpio_table[] = { /* F6 : NC */ PAD_NC(GPP_F6, NONE), /* F12 : GSXDOUT ==> EMR_INT_ODL */ - PAD_CFG_GPI_APIC(GPP_F12, NONE, PLTRST, LEVEL, INVERT), + PAD_CFG_GPI_INT(GPP_F12, NONE, PLTRST, LEVEL), /* F13 : SOC_PEN_DETECT_R_ODL ==> NC */ PAD_NC(GPP_F13, NONE), /* F15 : SOC_PEN_DETECT_OEL ==> NC */ diff --git a/src/mainboard/google/brya/variants/pirrha/overridetree.cb b/src/mainboard/google/brya/variants/pirrha/overridetree.cb index 50f37ba188..62b5a0a60c 100644 --- a/src/mainboard/google/brya/variants/pirrha/overridetree.cb +++ b/src/mainboard/google/brya/variants/pirrha/overridetree.cb @@ -391,7 +391,7 @@ chip soc/intel/alderlake chip drivers/i2c/hid register "generic.hid" = ""WCOM014B"" register "generic.desc" = ""WCOM Digitizer"" - register "generic.irq" = "ACPI_IRQ_LEVEL_LOW(GPP_F12_IRQ)" + register "generic.irq_gpio" = "ACPI_GPIO_IRQ_LEVEL_LOW(GPP_F12)" register "generic.enable_gpio" = "ACPI_GPIO_OUTPUT_ACTIVE_HIGH(GPP_C0)" register "generic.enable_delay_ms" = "20" register "generic.reset_gpio" = "ACPI_GPIO_OUTPUT_ACTIVE_LOW(GPP_F16)" -- cgit v1.2.3
