/****************************************************************************
* Name: sam_spi[n]select, sam_spi[n]status, and sam_spi[n]cmddata
*
* Description:
* These external functions must be provided by board-specific logic. They
* include:
*
* o sam_spi[n]select is a functions to manage the board-specific chip
* selects
* o sam_spi[n]status and sam_spi[n]cmddata: Implementations of the status
* and cmddata methods of the SPI interface defined by struct spi_ops_
* (see include/nuttx/spi/spi.h). All other methods including
* sam_spibus_initialize()) are provided by common SAMD/L logic.
*
* Where [n] is the SERCOM number for the SPI module.
*
* To use this common SPI logic on your board:
*
* 1. Provide logic in sam_boardinitialize() to configure SPI chip select
* pins.
* 2. Provide sam_spi[n]select() and sam_spi[n]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.
* 2. If CONFIG_SPI_CMDDATA is defined in the NuttX configuration, provide
* sam_spi[n]cmddata() functions in your board-specific logic. This
* function will perform cmd/data selection operations using GPIOs in
* the way your board is configured.
* 3. Add a call to sam_spibus_initialize() in your low level application
* initialization logic
* 4. The handle returned by sam_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).
*
****************************************************************************/
/****************************************************************************
* Name: sam_spi[n]select
*
* Description:
* PIO chip select pins may be programmed by the board specific logic in
* one of two different ways. First, the pins may be programmed as SPI
* peripherals. In that case, the pins are completely controlled by the
* SPI driver. This method still needs to be provided, but it may be only
* a stub.
*
* An alternative way to program the PIO chip select pins is as a normal
* GPIO output. In that case, the automatic control of the CS pins is
* bypassed and this function must provide control of the chip select.
* NOTE: In this case, the GPIO output pin does *not* have to be the
* same as the NPCS pin normal associated with the chip select number.
*
* Input Parameters:
* dev - SPI device info
* devid - Identifies the (logical) device
* selected - TRUE:Select the device, FALSE:De-select the device
*
* Returned Value:
* None

* Name: sam_spi[n]cmddata

* Description:
* Some SPI devices require an additional control to determine if the SPI

*
* This is often needed, for example, by LCD drivers. Some LCD hardware
* may be configured to use 9-bit data transfers with the 9th bit
* indicating command or data. That same hardware may be configurable,
* instead, to use 8-bit data but to require an additional, board-
* specific GPIO control to distinguish command and data. This function
* would be needed in that latter case.
*
* Input Parameters:
* dev - SPI device info
* devid - Identifies the (logical) device
*
* Returned Value:
* Zero on success; a negated errno on failure.
