Allwinner A31 DSI Encoder
=========================
The DSI pipeline consists of two separate blocks: the DSI controller
itself, and its associated D-PHY.
DSI Encoder
-----------
The DSI Encoder generates the DSI signal from the TCON's.
Required properties:
- compatible: value must be one of:
* allwinner,sun6i-a31-mipi-dsi
- reg: base address and size of memory-mapped region
- interrupts: interrupt associated to this IP
- clocks: phandles to the clocks feeding the DSI encoder
* bus: the DSI interface clock
* mod: the DSI module clock
- clock-names: the clock names mentioned above
- phys: phandle to the D-PHY
- phy-names: must be "dphy"
- resets: phandle to the reset controller driving the encoder
- ports: A ports node with endpoint definitions as defined in
Documentation/devicetree/bindings/media/video-interfaces.txt. The
first port should be the input endpoint, usually coming from the
associated TCON.
Any MIPI-DSI device attached to this should be described according to
the bindings defined in ../mipi-dsi-bus.txt
D-PHY
-----
Required properties:
- compatible: value must be one of:
* allwinner,sun6i-a31-mipi-dphy
- reg: base address and size of memory-mapped region
- clocks: phandles to the clocks feeding the DSI encoder
* bus: the DSI interface clock
* mod: the DSI module clock
- clock-names: the clock names mentioned above
- resets: phandle to the reset controller driving the encoder
Example:
dsi0: dsi@1ca0000 {
compatible = "allwinner,sun6i-a31-mipi-dsi";
reg = <0x01ca0000 0x1000>;
interrupts = <GIC_SPI 89 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&ccu CLK_BUS_MIPI_DSI>,
<&ccu CLK_DSI_SCLK>;
clock-names = "bus", "mod";
resets = <&ccu RST_BUS_MIPI_DSI>;
phys = <&dphy0>;
phy-names = "dphy";
#address-cells = <1>;
#size-cells = <0>;
panel@0 {
compatible = "bananapi,lhr050h41", "ilitek,ili9881c";
reg = <0>;
power-gpios = <&pio 1 7 GPIO_ACTIVE_HIGH>; /* PB07 */
reset-gpios = <&r_pio 0 5 GPIO_ACTIVE_LOW>; /* PL05 */
backlight = <&pwm_bl>;
};
ports {
#address-cells = <1>;
#size-cells = <0>;
port@0 {
#address-cells = <1>;
#size-cells = <0>;
reg = <0>;
dsi0_in_tcon0: endpoint {
remote-endpoint = <&tcon0_out_dsi0>;
};
};
};
};
dphy0: d-phy@1ca1000 {
compatible = "allwinner,sun6i-a31-mipi-dphy";
reg = <0x01ca1000 0x1000>;
clocks = <&ccu CLK_BUS_MIPI_DSI>,
<&ccu CLK_DSI_DPHY>;
clock-names = "bus", "mod";
resets = <&ccu RST_BUS_MIPI_DSI>;
#phy-cells = <0>;
};
