A delay is needed each time the chip selected becomes inactive, even after burst data readings are performed. Currently, there is no delay added after a burst reading and in case a new SPI transfer is performed before the needed delay, the adis device becomes unresponsive until reset. First patch adds the spi cs inactive delay in case it is not set and removes the additional chip select change delay present in adis APIs (to avoid a double delay). Second and third patch updates dt-bindings for the drivers which are affected by the first patch.
