From 5b3063802eeff8ff0dfbe40051b7a158448b489d Mon Sep 17 00:00:00 2001 From: Ivy Jian Date: Wed, 9 Jul 2025 10:42:34 +0800 Subject: [PATCH] mb/google/fatcat/var/kinmen: Fix touchscreen IRQ setting Previously, the touchscreen IRQ pin was not correctly configured to GPP_F18_IRQ, which caused an unexpected interrupt storm and led to the touchscreen becoming unresponsive. This change sets it to the correct configuration. (schematics version 20250611_v31) BUG=b:430200649 TEST= Ensure the touchscreen is working properly. Ensure the interrupt count increases only when the screen is touched via 'cat /proc/interrupts | grep ELAN' Change-Id: I20cc9632df76acdfafd2968ece0dde8ee95cc791 Signed-off-by: Ivy Jian Reviewed-on: https://review.coreboot.org/c/coreboot/+/88360 Tested-by: build bot (Jenkins) Reviewed-by: Subrata Banik Reviewed-by: Kapil Porwal --- src/mainboard/google/fatcat/variants/kinmen/overridetree.cb | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/mainboard/google/fatcat/variants/kinmen/overridetree.cb b/src/mainboard/google/fatcat/variants/kinmen/overridetree.cb index edf70986e9..aeda394cbf 100644 --- a/src/mainboard/google/fatcat/variants/kinmen/overridetree.cb +++ b/src/mainboard/google/fatcat/variants/kinmen/overridetree.cb @@ -251,7 +251,7 @@ chip soc/intel/pantherlake chip drivers/i2c/hid register "generic.hid" = ""ELAN9004"" register "generic.desc" = ""ELAN Touchscreen"" - register "generic.irq" = "ACPI_IRQ_LEVEL_LOW(GPP_F18)" + register "generic.irq" = "ACPI_IRQ_LEVEL_LOW(GPP_F18_IRQ)" register "generic.detect" = "1" register "generic.reset_gpio" = "ACPI_GPIO_OUTPUT_ACTIVE_LOW(GPP_F16)" register "generic.reset_delay_ms" = "150"
