    ARM: dts: sun5i: Add dts file for the Empire Electronix D709 tablet · 12ec9384
    Hans de Goede authored
    The Empire Electronix D709 tablet is a fairly standard 7" A13 tablet,
    featuring usb-wifi, a micro-sd slot, micro-usb otg and headphone jack.
    
    Empire Electronix is written on the back of the tablet, the D709 model
    info can be found in the about tablet menu in android.
    
    The PCB has no markings to speak of.
    
    This dts file does not add support for the ft5x touchscreen found at
    i2c bus 1, addr 0x38, irq PG11, because it does not work out of the box.
    It seems it has been flashed with the wrong firmware and needs to have
    alternative firmware uploaded at boot to make the touchscreen work
    properly, when hot-booting from android into an upstream kernel the
    touchscreen does work.
    
    The Memsic MXC622X accelerometer at i2c bus 1, addr 0x15 also is not
    enabled as there is no driver for it.
