The fref and the tcxo clocks settings are optional in some platforms.
|
|
WiLink8 doesn't need either, so we don't check the values. WiLink 6
|
|
only needs the fref clock, so we check that it is valid or return with
|
|
an error. WiLink7 needs both clocks, if either is not available we
|
|
return with an error.
