dt-bindings: display: convert samsung,ld9040 to DT Schema
v2: - drop use of spi-slave.yaml (Maxime) - added unevaluatedProperties (Maxime) - added type to width/height properties (Rob) Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Reviewed-by: Rob Herring <robh@kernel.org> Cc: Maxime Ripard <mripard@kernel.org> Cc: Rob Herring <robh@kernel.org> Cc: Andrzej Hajda <a.hajda@samsung.com> Cc: Thierry Reding <thierry.reding@gmail.com> Cc: Sam Ravnborg <sam@ravnborg.org> Link: https://patchwork.freedesktop.org/patch/msgid/20200408195109.32692-23-sam@ravnborg.org

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.
