spi based seps525 framebuffer display driver
|
|
|
|
Driver for seps525 display controller (in spi mode), This binding supports selection
|
|
of spi chipselect, spi max frequency, gpio to drive dc and reset pin of seps525
|
|
controller and spi transaction bit length.
|
|
|
|
Required properties:
|
|
- compatible: "syncoam,seps525"
|
|
- reg: Specifies the chip-select the seps525 is connected to on the spi bus
|
|
- reset-gpios: gpio connected to reset pin of seps525 controller.
|
|
- dc-gpios: gpio connected to dc pin of seps525 controller:
|
|
- buswidth: bitlength of each spi transaction
|
|
|
|
Example:
|
|
displayspi@0 {
|
|
compatible = "syncoam,seps525";
|
|
reg = <0>;
|
|
spi-max-frequency = <10000000>;
|
|
spi-cpol;
|
|
spi-cpha;
|
|
buswidth = <8>;
|
|
reset-gpios = <&gpio 0x1c GPIO_ACTIVE_LOW>;
|
|
dc-gpios = <&gpio 0x1b GPIO_ACTIVE_HIGH>;
|
|
};
