13       SPI Duplex mode, full or half. By default it's always full duplex thus 0
14       as this is, by far, the most common mode.
15       Selecting half duplex allows to use SPI MOSI as a bidirectional line,

21   mipi-cpol:
24       SPI clock polarity which indicates the clock idle state.
25       If it is used, the clock idle state is logic high; otherwise, low.
26   mipi-cpha:
29       SPI clock phase that indicates on which edge data is sampled.
31   mipi-hold-cs:
34       In some cases, it is necessary for the master to manage SPI chip select
35       under software control, so that multiple spi transactions can be performed
36       without releasing it. A typical use case is variable length SPI packets
37       where the first spi transaction reads the length and the second spi transaction
