> I used the following workaround. I created dummy nodes using the gpio-led
driver for the pins which requires pull up or pull down set. So my config
looks now like :
/ {
...
dummy_pullup {
compatible = "gpio-leds";
pinctrl-names = "default";
pinctrl-0 = <&pullup_pins>;
};
dummy_pulldown {
compatible = "gpio-leds";
pinctrl-names = "default";
pinctrl-0 = <&dogm162cs_pin>;
};
};
&pio {
...
pullup_pins: pullup_pins@0 {
pins = "PH20", "PH21","PI20", "PI21", "PI17", "PI18";
function = "gpio_in";
bias-pull-up;
};
/* CS PIN for LCD display */
dogm162cs_pin: dogm162cs_pin@0 {
pins = "PH0";
function = "gpio_in";
bias-pull-down;
};
};
