-Samsung LD9040 AMOLED LCD parallel RGB panel with SPI control bus
-
-Required properties:
- - compatible: "samsung,ld9040"
- - reg: address of the panel on SPI bus
- - vdd3-supply: core voltage supply
- - vci-supply: voltage supply for analog circuits
- - reset-gpios: a GPIO spec for the reset pin
- - display-timings: timings for the connected panel according to [1]
-
-The panel must obey rules for SPI slave device specified in document [2].
-
-Optional properties:
- - power-on-delay: delay after turning regulators on [ms]
- - reset-delay: delay after reset sequence [ms]
- - 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 [3]. This
-node should describe panel's video bus.
