| 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. |
