    Subject[PATCH 2/2] fbdev: ssd1307fb: add ssd1309 support
    Date
    The ssd1307fb driver supports a lot of chips from the ssd130xfb series.
    This patch adds the ssd1309 chip, a 128x64 OLED driver chip. It is very
    similar to the other chips and only has some definitions added to
    support it.
