-/* Nokia 6100 Configuration Settings:
- *
- * CONFIG_NOKIA6100_SPIMODE - Controls the SPI mode
- * CONFIG_NOKIA6100_FREQUENCY - Define to use a different bus frequency
- * CONFIG_NOKIA6100_NINTERFACES - Specifies the number of physical Nokia
- * 6100 devices that will be supported.
- * CONFIG_NOKIA6100_BPP - Device supports 8, 12, and 16 bits per pixel.
- * CONFIG_NOKIA6100_S1D15G10 - Selects the Epson S1D15G10 display controller
- * CONFIG_NOKIA6100_PCF8833 - Selects the Phillips PCF8833 display controller
- * CONFIG_NOKIA6100_BLINIT - Initial backlight setting
- *
- * The following may need to be tuned for your hardware:
- * CONFIG_NOKIA6100_INVERT - Display inversion, 0 or 1, Default: 1
- * CONFIG_NOKIA6100_MY - Display row direction, 0 or 1, Default: 0
- * CONFIG_NOKIA6100_MX - Display column direction, 0 or 1, Default: 1
- * CONFIG_NOKIA6100_V - Display address direction, 0 or 1, Default: 0
- * CONFIG_NOKIA6100_ML - Display scan direction, 0 or 1, Default: 0
- * CONFIG_NOKIA6100_RGBORD - Display RGB order, 0 or 1, Default: 0
- *
- * Required LCD driver settings:
- * CONFIG_LCD_NOKIA6100 - Enable Nokia 6100 support
- * CONFIG_LCD_MAXCONTRAST - must be 63 with the Epson controller and 127 with
- * the Phillips controller.
- * CONFIG_LCD_MAXPOWER - Maximum value of backlight setting. The backlight
- * control is managed outside of the 6100 driver so this value has no
- * meaning to the driver. Board-specific logic may place restrictions on
- * this value.

- * Name: nokia_lcdinitialize
- *
- * Description:
- * Initialize the NOKIA6100 video hardware. The initial state of the LCD is fully
- * initialized, display memory cleared, and the LCD ready to use, but with the power
- * setting at 0 (full off == sleep mode).
- *
- * Input Parameters:
- *
- * spi - A reference to the SPI driver instance.
- * devno - A value in the range of 0 throuh CONFIG_NOKIA6100_NINTERFACES-1. This
- * allows support for multiple LCD devices.
- *
- * Returned Value:
- *
- * On success, this function returns a reference to the LCD object for the specified
- * LCD. NULL is returned on any failure.
