| Device driver initialization priority. |
| Device is connected to SPI bus, it has to |
| be initialized after SPI driver. |

| config SPI_FLASH_W25QXXDV_SPI_FREQ_0 |
| int "SPI system frequency" |
| default 8000000 |
| help |
| This option sets the SPI controller's frequency. Beware this value |
| depends on the SPI controller being used and also on the system |
| clock. |

| config SPI_FLASH_W25QXXDV_SPI_SLAVE |
| int "SPI slave linked to SPI flash" |
| help |
| This option sets the SPI slave number the SPI controller has to switch |
| to when dealing with WinBond SPI flash chip. |

| config SPI_FLASH_W25QXXDV_GPIO_SPI_CS |
| bool "Manage SPI CS through a GPIO pin" |
| help |
| This option is useful if one needs to manage SPI CS through a GPIO |
| pin to by-pass the SPI controller's CS logic. |

| string "GPIO driver's name to use to drive SPI CS through" |
| depends on SPI_FLASH_W25QXXDV_GPIO_SPI_CS |
| help |
| This option is mandatory to set which GPIO controller to use in order |
| to actually emulate the SPI CS. |

| This is the device ID of the flash chip to use, which is 0x00ef4015 for |
| the W25QXXDV |
