mb/google/brya/var/xol: Change touchpad I2C interrupt type to GPIO_INT
If user continues to use the touchpad for over 3 minutes on Xol, the pointer movement is stuttering. Touchpad I2C transaction should appear during the interrupt signal level is low, but we could see some more I2C transaction after the interrupt signal(GPP_F14) went to high. We found experimentally that changing the interrupt type to GPIO_INT from APIC_IRQ improved this issue. We are still investigating, would like to apply this change first for Xol's dogfooding. BUG=b:350609957 BRANCH=brya TEST=built and verified there's no stuttering issue on touchpad movement Change-Id: Ie1b59355a694e5a42367a20e03f6c5f93225e79c Signed-off-by: Seunghwan Kim <sh_.kim@samsung.corp-partner.google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/83346 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Subrata Banik <subratabanik@google.com> Reviewed-by: YH Lin <yueherngl@google.com>
