* Name: nrf53_spi0/1/...select and nrf53_spi0/1/...status

|

* Description:
|
||||
* The external functions, nrf53_spi0/1/...select, nrf53_spi0/1/...status,
|
||||
* and nrf53_spi0/1/...cmddata must be provided by board-specific logic.
|
||||
* These are implementations of the select, status, and cmddata methods of
|
||||
* the SPI interface defined by struct spi_ops_s (include/nuttx/spi/spi.h).
|
||||
* All other methods (including nrf53_spibus_initialize()) are provided by
|
||||
* common NRF53 logic. To use this common SPI logic on your board:
|
||||
*
|
||||
* 1. Provide logic in nrf53_boardinitialize() to configure SPI chip select
|
||||
* pins.
|
||||
* 2. Provide nrf53_spi0/1/...select() and nrf53_spi0/1/...status()
|
||||
* functions in your board-specific logic. These functions will perform
|
||||
* chip selection and status operations using GPIOs in the way your
|
||||
* board is configured.
|
||||
* 3. If CONFIG_SPI_CMDDATA is defined in your NuttX configuration file,
|
||||
* then provide nrf53_spi0/1/...cmddata() functions in your
|
||||
* board-specific logic. These functions will perform cmd/data selection
|
||||
* operations using GPIOs in the way your board is configured.
|
||||
* 4. Add a calls to nrf53_spibus_initialize() in your low level
|
||||
* application initialization logic.
|
||||
* 5. The handle returned by nrf53_spibus_initialize() may then be used to
|
||||
* bind the SPI driver to higher level logic (e.g., calling
|
||||
* mmcsd_spislotinitialize(), for example, will bind the SPI driver to
|
||||
* the SPI MMC/SD driver).
