+Samsung S6E3HA2 5.7" 1440x2560 AMOLED panel
+
+Required properties:
+  - compatible: "samsung,s6e3ha2"
+  - reg: the virtual channel number of a DSI peripheral
+  - vdd3-supply: I/O voltage supply
+  - vci-supply: voltage supply for analog circuits
+  - reset-gpios: a GPIO spec for the reset pin (active low)
+  - enable-gpios: a GPIO spec for the panel enable pin (active high)
+
+Optional properties:
+  - te-gpios: a GPIO spec for the tearing effect synchronization signal
+    gpio pin (active high)
+
+Example:
+&dsi {
+        ...
+
+        panel@0 {
+                compatible = "samsung,s6e3ha2";
