Fields

name: String

The user-visible name of the SPI controller port.

mode: Option<TransferMode>

bits_per_word: Option<u32>

Number of bits in each SPI transmissiong “word”.

bits_per_sec: Option<u32>

Data communication rate in bits/second.

serial_clock: Option<String>

Which GPIO pin should be used for clock.

host_out_device_in: Option<String>

Which GPIO pin should be used for signal from debugger to OpenTitan.

host_in_device_out: Option<String>

Which GPIO pin should be used for signal from OpenTitan to debugger.

chip_select: Option<String>

Which GPIO pin should be used for chip select.

alias_of: Option<String>

Name of the SPI controller as defined by the transport.
