Tudor Ambarus 80a38bfbbd spi: dt-bindings: introduce FIFO depth properties ... There are SPI IPs that can be configured by the integrator with a specific FIFO depth depending on the system's capabilities. For example, the samsung USI SPI IP can be configured by the integrator with a TX/RX FIFO from 8 byte to 256 bytes. Introduce the ``fifo-depth`` property for such instances of IPs where the same FIFO depth is used for both RX and TX. Introduce ``rx-fifo-depth`` and ``tx-fifo-depth`` properties for cases where the RX FIFO depth is different from the TX FIFO depth. Make the dedicated RX/TX properties dependent on each other and mutual exclusive with the other.
