BROADCOM Cygnus Audio I2S/TDM/SPDIF controller
|
||||
|
||||
Required properties:
|
||||
- compatible : "brcm,cygnus-audio"
|
||||
- #address-cells: 32bit valued, 1 cell.
|
||||
- #size-cells: 32bit valued, 0 cell.
|
||||
- reg : Should contain audio registers location and length
|
||||
- reg-names: names of the registers listed in "reg" property
|
||||
Valid names are "aud" and "i2s_in". "aud" contains a
|
||||
set of DMA, I2S_OUT and SPDIF registers. "i2s_in" contains
|
||||
a set of I2S_IN registers.
|
||||
- clocks: PLL and leaf clocks used by audio ports
|
||||
- assigned-clocks: PLL and leaf clocks
|
||||
- assigned-clock-parents: parent clocks of the assigned clocks
|
||||
(usually the PLL)
|
||||
- assigned-clock-rates: List of clock frequencies of the
|
||||
assigned clocks
|
||||
- clock-names: names of 3 leaf clocks used by audio ports
|
||||
Valid names are "ch0_audio", "ch1_audio", "ch2_audio"
|
||||
- interrupts: audio DMA interrupt number
|
||||
|
||||
SSP Subnode properties:
|
||||
- reg: The index of ssp port interface to use
|
||||
Valid value are 0, 1, 2, or 3 (for spdif)
|
||||
|
||||
Example:
|
||||
cygnus_audio: audio@180ae000 {
|

#size-cells = <0>;
|
||||
reg = <0x180ae000 0xafd>, <0x180aec00 0x1f8>;
|
||||
reg-names = "aud", "i2s_in";
|
||||
clocks = <&audiopll BCM_CYGNUS_AUDIOPLL_CH0>,
|
||||
<&audiopll BCM_CYGNUS_AUDIOPLL_CH1>,
|
||||
<&audiopll BCM_CYGNUS_AUDIOPLL_CH2>;
|

|

|
||||
assigned-clock-rates = <1769470191>,
|
||||
<0>,
|
||||
<0>,
|
||||
<0>;
|
||||
clock-names = "ch0_audio", "ch1_audio", "ch2_audio";
|
||||
interrupts = <GIC_SPI 143 IRQ_TYPE_LEVEL_HIGH>;
|
||||
|
||||
ssp0: ssp_port@0 {
|
||||
reg = <0>;
|
||||
status = "okay";

ssp1: ssp_port@1 {
|
||||
reg = <1>;
|

status = "disabled";

ssp2: ssp_port@2 {
|
||||
reg = <2>;
|
||||
status = "disabled";
|
