1498 bool "Use external clock signal as a source of main clock for AT91 platforms"
1499 depends on ARCH_AT91

1501 help
1502 Use external 8 to 24 Mhz clock signal as source of main clock instead
1503 of an external crystal oscillator.
1504 This option disables the internal driving on the XOUT pin.
1505 The external source has to provide a stable clock on the XIN pin.
1506 If this option is disabled, the SoC expects a crystal oscillator
1507 that needs driving on both XIN and XOUT lines.
