mb/ocp/tiogapass/gpio: undo set trig and bufdis for NF pads
According to the documentation [1], RX Level/Edge Configuration (trig) and GPIO Tx/Rx Buffer Disable (bufdis) [2] settings are not applicable in native mode and BIOS does not need to configure them. Therefore, there is no need to configure this in gpio.h using PAD_CFG_NF_BUF_TRIG macros. Use PAD_CFG_NF instead and set these fields to 0. [1] Intel document #549921 [2] Intel document #336067-007US This is part of the patch set "src/mb/*, src/soc/intel/common/gpio: Remove PAD_CFG_NF_BUF_TRIG ": CB:43455 - cedarisland: undo set trig and bufdis for NF pads CB:43454 - tiogapass: undo set trig and bufdis for NF pads CB:43561 - h110m: undo set trig and bufdis for NF pads CB:43569 - soc/intel/common/gpio_defs: Remove PAD_CFG_NF_BUF_TRIG Change-Id: Icdb6cb39934548e125461929701b33477a74f2a2 Signed-off-by: Maxim Polyakov <max.senia.poliak@gmail.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/43454 Reviewed-by: Michael Niewöhner Reviewed-by: Lance Zhao Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
