spi-sck-cs-delay:
type: int
description: |
A delay in nanoseconds between the stop of clock signal and
deactivating Chip Select at the stop of transfer. If CS remains
asserted between transfer, this delay will be inserted between transfer.
If not set, the minimum supported delay is used.
This value will affect to all inner CS signals of SPI module when active.
This value will not be applied for CS lines controlled by GPIO.
spi-cs-sck-delay:
type: int
description: |
A delay in nanoseconds between activating Chip Select and the start
of clock signal at the start of transfer. If CS remains asserted
between transfer, this delay will be inserted between transfer.
If not set, the minimum supported delay is used.
This value will affect to all inner CS signals of SPI module when active.
This value will not be applied for CS lines controlled by GPIO.
spi-cs-cs-delay:
type: int
description: |
A delay in nanoseconds between deactivating Chip Select at the stop
of previous transfer and activating Chip Select at the start of
next transfer. If CS remains asserted between transfer, this delay
will not be inserted.
If not set, the minimum supported delay is used.
This value will affect to all inner CS signals of SPI module when active.
This value will not be applied for CS lines controlled by GPIO.
