4 # Common fields for SPI devices
8 on-bus: spi
13 spi-max-frequency:
16 description: Maximum clock frequency of device's SPI interface in Hz
24 list (see dt-bindings/spi/spi.h)
37 list (see dt-bindings/spi/spi.h)
43 spi-cpol:
46 SPI clock polarity which indicates the clock idle state.
48 spi-cpha:
51 SPI clock phase that indicates on which edge data is sampled.
53 spi-hold-cs:
56 In some cases, it is necessary for the master to manage SPI chip select
57 under software control, so that multiple spi transactions can be performed
58 without releasing it. A typical use case is variable length SPI packets
59 where the first spi transaction reads the length and the second spi transaction
