Read the clock nodes from the device tree and use them to set the
|
|
frequency for the refclock and the tcxo clock.
|
|
|
|
Also, call sdio_set_drvdata() earlier, so the glue is already set in
|
|
the driver data when we call wlcore_get_pdata_from_of() and we don't
|
|
need to pass it as a parameter.
