It is used in the Seeed RGB Backlight LCD [0] which has the LCD at the I2C address 0x3e. (A PCA9633 is also available at 0x62, to control the RGB backlight) This series introduces a new Vendor prefix for JHD, and introduces bindings for the LCD controller. A driver for the JHD1313 is added to the auxdisplay subsystem providing a charlcd to control the display. [0] http://wiki.seeedstudio.com/Grove-LCD_RGB_Backlight/ Because this interface is quite common, and generic - this could be potentially extended to other similar devices later, possibly with optional bindings to configure the display width and height. If so - perhaps a more generic naming for the binding/driver might be appropriate at that time.
