This patch adds DT bindings for s6e3fa0 panel.
The bindings describes panel resources, display timings and cpu timings.
Changelog v2:
- Adds unit address (commented by Sachin Kamat)
Changelog v3:
- Removes optional delay, size properties (commented by Laurent Pinchart)
- Adds OLED detection, TE gpio properties
Changelog v4:
- Moves CPU timings relevant properties from FIMD DT

+Samsung S6E3FA0 AMOLED LCD 5.7 inch panel
+
+Required properties:
+ - compatible: "samsung,s6e3fa0"
+ - reg: the virtual channel number of a DSI peripheral
+ - vdd3-supply: core voltage supply
+ - vci-supply: voltage supply for analog circuits
+ - reset-gpio: a GPIO spec for the reset pin
+ - det-gpio: a GPIO spec for the OLED detection pin
+ - te-gpio: a GPIO spec for the TE pin
+ - display-timings: timings for the connected panel as described by [1]
+ - cpu-timings: CPU interface timings for the connected panel, and it contains
+ following optional properties.
+ - cs-setup: clock cycles for the active period of address signal
+ enable until chip select is enable in CPU interface
+ - wr-setup: clock cycles for the active period of CS signal enable
+ until write signal is enable in CPU interface
+ - wr-act: clock cycles for the active period of CS enable in CPU
+ interface
+ - wr-hold: clock cycles for the active period of CS disable until
+ write signal is disable in CPU interface
+
+Optional properties:
+
+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.
