bool "NPCX clock controller driver"
depends on SOC_FAMILY_NPCX
help
Enable support for NPCX clock controller driver.
config CLOCK_CONTROL_NPCX_EXTERNAL_SRC
bool "Generate LFCLK by on-chip Crystal Oscillator"
depends on CLOCK_CONTROL_NPCX
help
When this option is enabled, the internal 32.768 KHz clock (LFCLK)
is generated by the on-chip Crystal Oscillator (XTOSC).
This includes an on-chip oscillator, to which an external crystal
and the related passive components are connected.
