device-tree bindings for rockchip Transport Stream Processing Module (TSP)
|
|
|
|
TSP is designed for processing Transport Stream Packets,
|
|
including receiving TS packets, PID filtering, TS descrambling,
|
|
De-multiplexing and TS outputting.Processed data are transferred to
|
|
memory buffer which are continued to be processing by software.
|
|
|
|
Required properties:
|
|
- compatible: value should be one of the following
|
|
"rockchip,rk312x-tsp";
|
|
"rockchip,rk3228-tsp";
|
|
"rockchip,rk3288-tsp";
|
|
"rockchip,rk3328-tsp";
|
|
"rockchip,rk3368-tsp";
|
|
|
|
- reg : offset and length of the register set for the device.
|
|
|
|
- interrupts: TSP interrupt specifier.
|
|
|
|
- interrupts-name: should be "irq_tsp".
|
|
|
|
- clocks: phandle to TSP sclk/hclk/aclk clocks
|
|
|
|
- clock-names: should be "clk_tsp", "hclk_tsp" and "aclk_tsp"
|
|
|
|
- pinctrl-names: use "default"
|
|
|
|
- pinctrl-0: pin config for iomux
|
|
|
|
Example:
|
|
SoC-specific DT entry:
|
|
tsp: tsp@ff050000 {
|
|
compatible = "rockchip,rk3328-tsp";
|
|
reg = <0x0 0xff050000 0x0 0x10000>;
|
|
rockchip,grf = <&grf>;
|
|
interrupts = <GIC_SPI 72 IRQ_TYPE_LEVEL_HIGH>;
|
|
interrupt-names = "irq_tsp";
|
|
clocks = <&cru SCLK_TSP>, <&cru ACLK_TSP>, <&cru HCLK_TSP>;
|
|
clock-names = "clk_tsp", "aclk_tsp", "hclk_tsp";
|
|
pinctrl-names = "default";
|
|
pinctrl-0 = <&tsp_d0
