    Subject[PATCH v3 11/11] ARM: dts: at91: sama5d2: Add resistive touch device
    Date
    Add generic resistive touch device which is connected to ADC block
    inside the SAMA5D2 SoC

    Signed-off-by: Eugen Hristev <eugen.hristev@microchip.com>
    ---
    Changes in v3:
    - modified compatible and threshold to adapt to changed bindings

    Changes in v2:
    - now added a generic resistive touchscreen node instead of architecture
    specific
