+ * CONFIG_UG2864AMBAG01_NINTERFACES - Specifies the number of physical UG-2864AMBAG01
+ *   devices that will be supported.
+ * CONFIG_UG2864AMBAG01_FRAMEBUFFER - If defined, accesses will be performed using an
+ *   in-memory copy of the OLEDs GDDRAM.  This cost of this buffer is 128 * 64 / 8 =
+ *   1Kb.
+ *
+ *   If CONFIG_UG2864AMBAG01_FRAMEBUFFER is not defined and the LCD is a LANDSCAPE mode,
+ *   then a 128 byte buffer is still required.

+ * Required LCD driver settings:
+ *
+ * CONFIG_LCD_UG28AMBAG01 - Enable UG-2864AMBAG01 support
+ * CONFIG_LCD_MAXCONTRAST should be 255, but any value >0 and <=255 will be accepted.
+ * CONFIG_LCD_MAXPOWER must be 1
+ *
+ * Option LCD driver settings:
+ * CONFIG_LCD_LANDSCAPE, CONFIG_LCD_PORTRAIT, CONFIG_LCD_RLANDSCAPE, and
+ *   CONFIG_LCD_RPORTRAIT - Display orientation.
+ *
+ * Required SPI driver settings:
+ * CONFIG_SPI_CMDDATA - Include support for cmd/data selection.
