1826 +*
1827 +* "data" points to an array of pixels that define the cursor; each row should
1828 +* be a multiple of 32-bit values (i.e. 16 pixels). Each pixel is two bits,
1829 +* where the values are:
1830 +*
1831 +* 00 => transparent 01 => invert 10 => color1 11 => color2
1832 +*
1833 +* The data is arranged as follows (per word):
1834 +*
1835 +* bits: |31-30|29-28|27-26|25-24|23-22|21-20|19-18|17-16|
1836 +* pixel: | 12 | 13 | 14 | 15 | 8 | 9 | 10 | 11 |
1837 +* bits: |15-14|13-12|11-10| 9-8 | 7-6 | 5-4 | 3-2 | 1-0 |
1838 +* pixel: | 4 | 5 | 6 | 7 | 0 | 1 | 2 | 3 |
1839 +*
1840 +* Regardless of the frame buffer color depth, "color1", "color2",
1841 +* "blinkcolor1", and "blinkcolor2" are 24-bit colors since the cursor is
1842 +* injected into the data stream right before the video DAC.
1843 +*
1844 +* When "blinkrate" is not zero, pixel value 10 will alternate between "color1"
1845 +* and "blinkcolor1" (similar for pixel value 11 and "color2"/"blinkcolor2").
1846 +*
1847 +* "blinkrate" ranges between 0 and 255. When 0, blinking is disabled. 255 is
1848 +* the fastest blink rate and 1 is the slowest.
1849 +*
1850 +* Both "width" and "height" must be between 1 and 64; it is preferable to have
1851 +* "width" a multiple of 16.

1874 +* The line starts at ("x1","y1") and ends at ("x2","y2"). This means that
1875 +* when using a pattern, the two coordinates are not transitive (i.e. swapping
1876 +* ("x1","y1") with ("x2","y2") will not necessarily draw the exact same line,
1877 +* pattern-wise).
1878 +*
1879 +* "pattern" is a 2 to 16 bit pattern (since a 1 bit pattern isn't much of a
1880 +* pattern). The lower 16 bits define the pattern (1 being foreground, 0 being
1881 +* background or transparent), and bits 19-16 define the length of the pattern
1882 +* (as pattern length - 1). So, for example, "0xf00ff" defines a 16 bit
1883 +* with the first 8 pixels in the foreground color and the next 8 pixels in the
1884 +* background color or transparent.
1885 +*
1886 +* LINE_PRECISE is used to apply angularly corrected patterns to line. It
1887 +* should only be used when LINE_PATTERN is also set. The pattern will be
1888 +* applied along the length of the line, instead of along the length of the
1889 +* major axis. This may result in the loss of fine details in the pattern, and

1923 + * This driver works for the following two LCD:
1924 + * SHARP LM121VB1T01 - A dual scan 640x480 monochrome LCD.
1925 + * HOSIDEN HLM6323 - A single scan 320x240 monochrome LCD.
1926 + *
1927 + * And support two gray modes:
1928 + * 8 levels of gray - Actually is 7 levels of gray. Two of the levels
1929 + * have the same gray.
1930 + * 16 levels of gray - Extending the gray levels by switching the LUT
1931 + * for each frame.
