Subject[PATCH v2 2/3] dt-bindings: adis16475: Add 'spi-cs-inactive-delay-ns' property
Date
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.
