Add refclock and tcxoclock as clock providers in WiLink. These clocks
|
|
are not accesible outside the WiLink module, but they are registered
|
|
in the clock framework anyway. Only the WiLink chip consumes these
|
|
clocks.
|
|
|
|
In theory, the WiLink chip could be connected to external clocks
|
|
instead of using these internal clocks, so make the clock consumer
|
|
code generic enough. If external clocks are used, then the internal
|
|
clock device tree nodes are not necessary, but the external ones must
|
|
be specified.
