anomaly-58-workaround:
type: boolean
description: |
Enables the workaround for the nRF52832 SoC SPIM PAN 58 anomaly.
Must be used in conjunction with
CONFIG_SOC_NRF52832_ALLOW_SPIM_DESPITE_PAN_58=y
rx-delay-supported:
type: boolean
description: |
Indicates if the SPIM instance has the capability of delaying MISO
sampling. This property needs to be defined at SoC level DTS files.
rx-delay:
type: int

- 0
- 1
- 2
- 3
- 4
- 5
- 6
- 7
description: |
Number of 64 MHz clock cycles (15.625 ns) delay from the sampling edge
of SCK (leading or trailing, depending on the CPHA setting used) until
the input serial data on MISO is actually sampled. This property does
not have any effect if the rx-delay-supported property is not set.
