| |
The devices supported by adis16475 driver require a stall period between SPI transactions (during which the chip select is inactive), with a minimum value equal to 16 microseconds, thus adding 'spi-cs-inactive-delay-ns' property, which should indicate the stall time between consecutive SPI transactions. The specified minimum time may not be sufficient for all configurations.
