-King Display KD035G6-54NT 3.5" (320x240 pixels) 24-bit TFT LCD panel

-Required properties:
-- compatible: should be "kingdisplay,kd035g6-54nt"
-- power-supply: See panel-common.txt
-- reset-gpios: See panel-common.txt
-
-Optional properties:
-- backlight: see panel-common.txt
-
-The generic bindings for the SPI slaves documented in [1] also apply.
-
-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.
