Samsung S6E3HA2 5.7" 1440x2560 AMOLED panel

Required properties:
  - compatible: "samsung,s6e3ha2"
  - reg: the virtual channel number of a DSI peripheral
  - vdd3-supply: core voltage supply
  - vci-supply: voltage supply for analog circuits
  - reset-gpios: a GPIO spec for the reset pin
  - panel-en-gpios: a GPIO spec for the panel enable pin
  - te-gpios: a GPIO spec for the tearing effect synchronization signal gpio pin

Optional properties:
  - display-timings: timings for the connected panel as described by [1]
  - panel-width-mm: physical panel width [mm]
  - panel-height-mm: physical panel height [mm]

The device node can contain one 'port' child node with one child
'endpoint' node, according to the bindings defined in [2]. This
node should describe panel's video bus.
