arm64: dts: allwinner: a64-oceanic-5205-5inmfd: Enable GT911 CTP
Goodix GT911 CTP is bound with Oceanic 5205 5inMFD board. The CTP connected to board with, - SDA, SCK from i2c0 - GPIO-LD0 as AVDD28 supply - PH4 gpio as interrupt pin - PH11 gpio as reset pin - X axis is inverted - Y axis is inverted Signed-off-by: Jagan Teki <jagan@amarulasolutions.com> Signed-off-by: Maxime Ripard <maxime.ripard@bootlin.com>
