---help---
Number of additional nanoseconds to wait in PM_SLEEP before going to PM_STANDBY mode.
config STM32F429I_DISCO_ILI9341
bool "LCD driver for ILI9341 Liquid Crystal Display Controller"

---help---
Enables support for a connected display based on ili9341 LCD Single Chip
Driver. This sub driver supports only communication with the display driver
connected via 4-wire serial (spi) mcu interface.

---help---
This enables faster 16-bit spi mode for transmitting or receiving pixel data
to or from the display gram. But uses default 8-bit spi mode for all other
display operations.

---help---
Define the lcd interface which should be used. This must be
corresponding to the configured ili9341 lcd device in the driver
section.
