Renesas FSI
|
||||
|
||||
Required properties:
|
||||
- compatible : "renesas,fsi2-<soctype>",
|
||||
"renesas,sh_fsi2" or "renesas,sh_fsi" as
|
||||
fallback.
|
||||
Examples with soctypes are:
|
||||
- "renesas,fsi2-r8a7740" (R-Mobile A1)
|
||||
- "renesas,fsi2-sh73a0" (SH-Mobile AG5)
|
||||
- reg : Should contain the register physical address and length
|
||||
- interrupts : Should contain FSI interrupt
|
||||
|
||||
- fsia,spdif-connection : FSI is connected by S/PDIF
|
||||
- fsia,stream-mode-support : FSI supports 16bit stream mode.
|
||||
- fsia,use-internal-clock : FSI uses internal clock when master mode.
|
||||
|
||||
- fsib,spdif-connection : same as fsia
|
||||
- fsib,stream-mode-support : same as fsia
|
||||
- fsib,use-internal-clock : same as fsia
|
||||
|
||||
Example:
|
||||
|
||||
sh_fsi2: sh_fsi2@ec230000 {
|
||||
compatible = "renesas,sh_fsi2";
|
||||
reg = <0xec230000 0x400>;
|
||||
interrupts = <0 146 0x4>;
|
||||
|
||||
fsia,spdif-connection;
|
||||
fsia,stream-mode-support;
|
||||
fsia,use-internal-clock;
|
||||
};
