Has Dmitry agreed to be the maintainer here? Traditionally when adding
a new file one lists themselves.

Why two blank lines between reset-gpios and vccio-supply?

I think you want "panel" as a required property too, right?

quoted hunk ↗ jump to hunk
+examples:
+  - |
+    #include <dt-bindings/gpio/gpio.h>
+    #include <dt-bindings/interrupt-controller/irq.h>
+
+    i2c {
+      #address-cells = <1>;
+      #size-cells = <0>;
+
+      touchscreen: touchscreen@41 {
+        compatible = "ilitek,ili9882t";
+        reg = <0x41>;
+
+        interrupt-parent = <&pio>;
+        interrupts = <12 IRQ_TYPE_LEVEL_LOW>;
+
+        reset-gpios = <&pio 60 GPIO_ACTIVE_LOW>;
+        vccio-supply = <&mt6366_vio18_reg>;
...and "panel" would also need to go in the above example.
