Add Goodix GT5663 capacitive touch controller node on Amarula A64-Relic board. The CTP connected to board with, - SDA, SCK from i2c1 - GPIO-LD0 as AVDD28 supply - PH4 gpio as interrupt pin - PH8 gpio as reset pin - X axis is inverted - Y axis is inverted Signed-off-by: Jagan Teki <jagan@amarulasolutions.com> --- Changes for v4: - drop i2c1 pinctrl Changes for v3: - Use 2.8v for reg_ldo_io0 Changes for v2: - drop i2c1, bias-pull-up .../allwinner/sun50i-a64-amarula-relic.dts | 23 +++++++++++++++++++ 1 file changed, 23 insertions(+)
