bool "Nuvoton NPCX raw-keyboard-scan driver for the Zephyr shim"
depends on SOC_FAMILY_NPCX
default y
help
This option enables a driver for providing raw access to the
keyboard-scan peripheral in the chip. This is used instead of the
kscan interface so we can continue to use most of the existing
keyboard-scanning code in ECOS.
if CROS_KB_RAW_NPCX
config CROS_KB_RAW_NPCX_KSO_HIGH_DRIVE
bool "Enable quasi-bidirectional buffers for KSO pins"
help
This option enables quasi-bidirectional buffers for KSO pins. The
low-impedance high drive is active when ec changes the output data
buffers from 0 to 1, thereby reducing the low-to-high transition time.
