This commit adds a new Kconfig option CLOCK_CONTROL_NPCX_EXTERNAL_SRC. With this option enabled, the internal 32.768 KHz clock (LFCLK) is generated by the on-chip Crystal Oscillator (XTOSC). Otherwise, the LFCLK is generated by the Low-Frequency Clock Generator (LFCG). Signed-off-by: Jun Lin <CHLin56@nuvoton.com>

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.
