This patch removes the 1 milliseconds sleep and replace it with a 1 microseconds udelay which should be also okay for the reset pulse width. To change the state from RESET -> TRX_OFF the at86rf230 device needs 120 microseconds, this is a worst case of all at86rf* chips. Signed-off-by: Alexander Aring Signed-off-by: David S.
