23       - const: sifive,spi0
26       Should be "sifive,<chip>-spi" and "sifive,spi<version>".
27       Supported compatible strings are -
28       "sifive,fu540-c000-spi" and "sifive,fu740-c000-spi" for the SiFive SPI v0
29       as integrated onto the SiFive FU540 and FU740 chip resp, and "sifive,spi0"
30       for the SiFive SPI v0 IP block with no chip integration tweaks.
31       Please refer to sifive-blocks-ip-versioning.txt for details
