/* UG-9664HSWAG01 Configuration Settings:
*
* CONFIG_UG9664HSWAG01_SPIMODE - Controls the SPI mode
* CONFIG_UG9664HSWAG01_FREQUENCY - Define to use a different bus frequency
* CONFIG_UG9664HSWAG01_NINTERFACES - Specifies the number of physical
* UG-9664HSWAG01 devices that will be supported. NOTE: At present, this
* must be undefined or defined to be 1.
* CONFIG_UG9664HSWAG01_POWER
* If the hardware supports a controllable OLED a power supply, this
* configuration should be defined. (See ug_power() below).
*
* Required LCD driver settings:
* CONFIG_LCD_UG9664HSWAG01 - Enable UG-9664HSWAG01 support
* CONFIG_LCD_MAXCONTRAST should be 255, but any value >0 and <=255 will be
* accepted.
* CONFIG_LCD_MAXPOWER should be 2: 0=off, 1=dim, 2=normal
*
* Required SPI driver settings:
* CONFIG_SPI_CMDDATA - Include support for cmd/data selection.

* Name: ug_initialize
*
* Description:
* Initialize the UG-9664HSWAG01 video hardware. The initial state of the
* OLED is fully initialized, display memory cleared, and the OLED 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 through
* CONFIG_UG9664HSWAG01_NINTERFACES-1.
* This allows support for multiple OLED devices.
*
* Returned Value:
*
* On success, this function returns a reference to the LCD object for
* the specified OLED. NULL is returned on any failure.
