+* "data" points to an array of pixels that define the cursor; each row should
+* be a multiple of 32-bit values (i.e. 16 pixels). Each pixel is two bits,
+* where the values are:
+*
+* 00 => transparent 01 => invert 10 => color1 11 => color2
+*
+* The data is arranged as follows (per word):
+*
+* bits: |31-30|29-28|27-26|25-24|23-22|21-20|19-18|17-16|

+* bits: |15-14|13-12|11-10| 9-8 | 7-6 | 5-4 | 3-2 | 1-0 |
+* pixel: | 4 | 5 | 6 | 7 | 0 | 1 | 2 | 3 |
+*
+* Regardless of the frame buffer color depth, "color1", "color2",
+* "blinkcolor1", and "blinkcolor2" are 24-bit colors since the cursor is
+* injected into the data stream right before the video DAC.
+*
+* When "blinkrate" is not zero, pixel value 10 will alternate between "color1"
+* and "blinkcolor1" (similar for pixel value 11 and "color2"/"blinkcolor2").
+*
+* "blinkrate" ranges between 0 and 255. When 0, blinking is disabled. 255 is
+* the fastest blink rate and 1 is the slowest.
+*
+* Both "width" and "height" must be between 1 and 64; it is preferable to have
+* "width" a multiple of 16.

+* (as pattern length - 1). So, for example, "0xf00ff" defines a 16 bit
+* with the first 8 pixels in the foreground color and the next 8 pixels in the
+* background color or transparent.
+*
+* LINE_PRECISE is used to apply angularly corrected patterns to line. It
+* should only be used when LINE_PATTERN is also set. The pattern will be
+* applied along the length of the line, instead of along the length of the

+ * This driver works for the following two LCD:
+ * SHARP LM121VB1T01 - A dual scan 640x480 monochrome LCD.
+ * HOSIDEN HLM6323 - A single scan 320x240 monochrome LCD.
+ *
+ * And support two gray modes:
+ * 8 levels of gray - Actually is 7 levels of gray. Two of the levels
+ * have the same gray.
+ * 16 levels of gray - Extending the gray levels by switching the LUT
+ * for each frame.
+ *
