/* 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.

|
*
|
|
* 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 powersetting 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.
